1. 2. (Public domain.). Smaller magnitude earthquakes (M3.0+) may be felt by people close to the epicenters. This is compared to a peak of 54 earthquakes on August 10th, the day of the M4.6 mainshock, which remains the largest earthquake so far. Over the past 5 days, we have been carefully monitoring the earthquake swarm in the Salton Sea. Our updated probabilities for the following three scenarios reflect this reduction in activity; however, the risk of a large earthquake is still considerably elevated due to the swarm when compared to background levels. Earthquakes are continuing in the area of California's Salton Sea, and the U.S. Geological Survey says the event "significantly" raises the probability of a large quake in the region. Earthquakes of this size could cause damage around the area close to the earthquakes that have already occurred and would be followed by aftershocks that would increase the number of smaller earthquakes per day. (Public domain.). Environmental conditions are conducive for significant or even rapid strengthening before landfall on the evening of January 22 (LT) or the... A very bright fireball was spotted over Madrid at about 02:56 UTC on January 21, 2021, and recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN). Swarms recorded over the last 20 years have lasted between one and 20 days, with an average of a week, the U.S. Geological Survey (USGS) said in … This scenario occurred in a previous swarm in the area – in 1981, when a swarm in this region included a magnitude 5.8 earthquake. Southern California's Salton Sea, once a large natural lake fed by the Colorado River, may play an important role in the earthquake cycle of the southern San Andreas Fault and … During this earthquake swarm, the probability of larger earthquakes in this region is significantly greater than usual. During this earthquake swarm, the probability of larger earthquakes in this region is significantly greater than usual, the USGS said. The storm prompted more than 200 flood warnings, with five of them severe, and has... A powerful earthquake registered by PHIVOLCS as M7.1 hit off the coast of Mindanao, Philippines at 12:23 UTC (20:23 LT) on January 21, 2021. The swarm is centered just southeast of Salton Sea, near Westmorland in Imperial Valley, in an area with a history of intense swarms. If you value what we do here, please consider subscribing today. Some moderately sized earthquakes may occur (magnitude in the range M4.5-M5.4), which could cause localized damage, particularly in weak structures. There have now been about 115 total quakes in this … https://www.bing.com/covid/local/chinamainland Many Salton City residents said they did not feel the activity during the 24 swarm, but a gas station employee said she felt Saturday evening’s 3.5 magnitude earthquake. 2,216 earthquakes in the past 365 days. One uncertain aspect of this swarm is whether there will be any additional bursts of activity. The earthquake swarm that began on August 10th continues to quiet down, producing no earthquakes of magnitude 2 and larger in the last 24 hours (as of noon August 14th). Our updated probabilities for the following three scenarios reflect this reduction in activity; however, the risk of a large earthquake is still considerably elevated due to the swarm when compared to background levels. Circles are earthquake locations, red indicates an earthquake in the past hour, orange the past 24 hours, and yellow the past 7 days. While the swarm appears to have died down for the moment, this area may have future bursts of activity that will impact the probabilities discussed below. What is the difference between aftershocks and swarms. "They are in the Brawley Seismic Zone – a network of small faults that connect the San Andreas and Imperial faults. This was as of around 5:15pm Wednesday. In a typical week, there is approximately a 1 in 10,000 chance of a magnitude 7+ earthquake on the southernmost San Andreas Fault. Approximately 35 earthquakes have shook the area of Westmorland Wednesday in the span of 40 minutes. PALM SPRINGS, Calif. — Dr. Lucy Jones is a seismologist who is answering questions on what the swarm of earthquakes around the Salton Sea may mean for residents in Southern California. The southernmost section of the San Andreas Fault is capable of rupturing in large magnitude earthquakes (magnitude 7+), but the last earthquake that strong was more than 300 years ago. Massive earthquake swarm in Salton Sea could lead to major quake on the southern part of the san Andreas Fault. Geological evidence strongly indicates that it was tectonic movement through the ages that caused the region to subside hundreds of feet below sea level and create the basin the Salton Sea now occupies. Salton City has had: (M1.5 or greater) 2 earthquakes in the past 24 hours. — Steve Jobs, US computer engineer & industrialist, The Watchers — Watching the world evolve and transform, Except where otherwise noted, content on this site is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License, Rock avalanche with unusual runout pattern at Mount Darwin, New Zealand, Mongolia in the grip of one of its most extreme winters on record, Very dangerous Tropical Cyclone "Eloise" to make landfall near Beira, Mozambique, Large waterspout near the coast of Central Java, Indonesia, Slow-moving transient sparks vivid auroras around the Arctic circle, Unsettled to active geomagnetic field levels expected, G1 geomagnetic storm watch in effect, G1 - Minor geomagnetic storm watch in effect for December 23 and 24, AMS camera system detects meteor outburst of unknown origin, Bright fireball seen over wide areas of Japan, Researchers reconstruct 11-year solar cycles all the way back to year 969, Six Alaskan volcanoes may be part of one massive supervolcano, New map of Milky Way Galaxy shows Earth is 7 km/s faster and 2 000 LY closer to the galactic center, Scientists find 'superbolts' flashing 1 000 brighter than normal lightning, Heavy ashfall in Kozyrevsk after strong paroxysmal event at Klyuchevskoy volcano, Russia, Earthquake swarm in the vicinity of El Chichon volcano, Mexico, Slight rise in abnormal behavior at Mayon volcano, Philippines, Thousands evacuated as Storm Christoph hits UK with disruptive snow and historic flooding, Powerful M7.1 earthquake hits off the coast of Mindanao, Philippines, Asteroid 2021 BR2 flew past Earth at 0.19 LD, Increased activity at Raung volcano, Alert Level raised to 2 - Aviation Color Code to Orange, Indonesia, The Weekly Volcanic Activity Report: January 13 - 19, 2021, Sensors detect rare 'musical note' from magnetosphere over Norway, Earthquake swarm with magnitudes up to 6.0 near King George Island, Antarctica, Large fireball explodes over Galicia, loud boom reported, Spain, Heavy snowfall causes massive pileup of 130 vehicles in northeastern Japan, Earth is spinning faster than it has in 50 years, scientists reveal, Massive pyroclastic flow at Semeru volcano, Indonesia, 15 dead, 24 379 houses inundated as worst floods in 50 years hit South Kalimantan, Indonesia, Tropical Storm "Eloise" forecast to strike Madagascar and Mozambique, Large clay landslide leaves 26 people missing, 10 injured in Gjerdrum, Norway, Spectacular fireball explodes over China's Yushu City, the largest fireball event since December 2018, Major Sudden Stratospheric Warming (SSW) event expected as we enter 2021, Bright fireball explodes over Norway, ground impact recorded south of Løten, 2020 M6.4 Croatia earthquake aftershocks migrating north toward capital Zagreb, liquefaction, sinkholes reported, At least 81 people killed, hundreds injured as M6.2 earthquake hits West Sulawesi, Indonesia, Eloise makes landfall over Madagascar, conditions conducive for rapid re-intensification in the Mozambique Channel, Storm Christoph to bring widespread flooding to parts of UK and Ireland, major incident declared, Very strong and shallow M6.4 earthquake hits San Juan, Argentina, Severe floods and landslides damage more than 10 000 homes in West Java, death toll rises to 21 with 19 missing, Indonesia, Worst flooding in 50 years leaves 6 dead, 50 000 displaced in Malaysia, Powerful winter storm slams Japan with record snow, claims 10 lives and strands more than 1 200 vehicles, Intense cold waves bring rare snowfall to Taiwan, Historic snow engulfs capital Madrid just 2 days after Spain registered its coldest temperature on record, Yakutia sees longest cold spell in 14 years as Siberia quivers through abnormally harsh temperatures, New paroxysmal eruptive episode at Etna's Southeast Crater, Italy, Asteroid 2021 BO flew past Earth at 0.06 LD, Citizen scientists discover new, mysterious feature of aurora-like phenomenon STEVE, Research suggests water is naturally occurring on all rocky planets, CME impact detected, G3 - Strong geomagnetic storm watch remains but confidence diminishing, Long-duration C7.4 solar flare produces asymmetric full halo CME, impact expected on December 9, Moderately strong M4.4 solar flare erupts, CME produced, Study: Modern Grand Solar Minimum (2020 - 2053) leads to cooling, important implications for entire planet, Donald Scott: Parker Solar Probe and the Electric Sun, Quantum experiment shows objective reality does not exist, Forecasting earthquakes 5 days ahead, research, Creative Commons Attribution-NonCommercial 4.0 International License. The location of the geothermal field at the southern end of the San Andreas fault is cause for concern due to the … Five of the seven meteor paths intersected in an area just east of the 3rd magnitude star... An international team of researchers reconstructed the Sun's 11-year cycles all the way back to year 969 using measurements of radioactive carbon in tree rings. Only one of these scenarios will occur within the next week, USGS said. The U.S. Geological Survey advises everyone to be aware of the possibility of future earthquakes, especially when in or around vulnerable structures such as unreinforced masonry buildings. (adsbygoogle = window.adsbygoogle || []).push({}); According to the USGS, there is approximately a 3 in 10 000 chance of a magnitude 7+ earthquake in the vicinity of this swarm in a typical week. The rock avalanche was first spotted... A large waterspout formed in Gajah Mungkur Reservoir at Wonogiri, Central Java, Indonesia at around 16:30 LT on January 20, 2021. In the past 24 hours, we have been carefully monitoring the Salton Sea for ongoing earthquake activity. Dozens of minor earthquakes, ranging from 2.0 to 4.6, shook the Salton Sea Monday.The swarm of earthquakes were centered about 8 miles from the southern end of the San Andreas Fault. The largest earthquake in the region of the Salton Sea Geothermal Field during the 30-year study period was a magnitude 5.1 earthquake. Our updated probabilities for the following three scenarios reflect this reduction in activity. Salton Buttes volcano lava domes -40 m / -131 feet California, Canada and USA (mainland), 33.2°N / -115.62°W Current status: normal or dormant (1 out of 5) That probability is significantly elevated while swarm activity remains high. Since the swarm activity has subsided, we will no longer be updating this forecast; however, this does not mean the risk of a larger earthquake is gone. Scenario 2 (less likely): A larger earthquake (magnitude 5.5 to 6.9) could occur within the next 7 days. Historically, this area has seen swarms before – most recently in 2001, 2009, and 2016. The findings help scientists better understand the dynamics of the Sun, enabling more accurate dating... Mayon volcano in Albay, Philippines exhibited a slight increase in abnormal behavior over the past 48 hours, the Philippine Institute of Volcanology and Seismology (Phivolcs) Lignon Hill Observatory reported on Thursday, January 21, 2021. During the last swarm in 2016, there were three bursts of activity separated by relatively quiet periods before the swarm ended. 2. This swarm did not decrease the potential for a larger earthquake in the future and Southern California continues to be one of the most seismically active areas in the nation. Posted by Teo BlaÅ¡ković on October 1, 2020 at 07:41 UTC (3 months ago) Categories: Featured articles, Seismic activity. The agency is reporting a depth of 116 km (72 miles). Updated forecasts will be released on the USGS Earthquake Hazard Program website.For media inquires, please contact Paul Laustsen at plaustsen@usgs.gov. The nearby San Andreas fault, however, is capable of unleashing extremely destructive earthquakes of at least magnitude 8, Brodsky said. Most geologists believe the basin where the Salton Sea is now located was never part of the Gulf of California / Sea of Cortez and was actually far above sea level in the distant past. Monitoring of earthquake activity began in the 1930s, and the dense seismic network installed in the 1970s is operated by the USGS and the California Institute of … A swarm of small earthquakes in California, close to the Mexican border, is being closely monitored as to whether it might raise the chance of a much larger event on the San Andreas fault. We calculate this earthquake forecast using a statistical analysis based on past earthquakes. #California #Earthquake […] We are carefully monitoring activity throughout the region and will continue to provide information to help people stay safe and care for themselves and each other. Sam Rivera lives in Salton City and the first thing she noticed were her closet doors shaking, she said, “My house is a double trailer, so it kind of just moves a little bit like if there was wind, that is it.” The following three scenarios describe the possibilities of what could happen from September 30 to October 6, according to the USGS forecast released on September 30. "None of the earthquakes that have been happening in the Imperial Valley are anywhere near the San Andreas fault," Jones added. The current swarm is occurring about 40 kilometers (25 miles) to the south of the swarm that occurred near Bombay Beach in August 2020. The swarm is centered just southeast of Salton Sea, near Westmorland in Imperial Valley, in an area with a history of intense swarms. Earthquakes of this size could cause damage around the Salton Sea area and would be followed by aftershocks that would increase the number of smaller earthquakes per day. About half of the swarms in this area are over within a week. The volcano's... Around 2 300 homes have been evacuated overnight Thursday, January 21, 2021, amid widespread flooding and dangerous snow across parts of the United Kingdom brought by Storm Christoph. Over the past 48 hours, we have been carefully monitoring the Salton Sea for ongoing earthquake activity. “With earthquakes, it’s just like real estate and it's location, location, location. While this scenario has a very small probability of occurring, if such an earthquake were to occur, it would have serious impacts in the region and would be followed by its own aftershocks. For the next week, we estimate an elevated chance of such an earthquake to be about 1 in 1,000. The Salton Buttes are rhyolite volcanoes that lie in and along the Sea and may have erupted as recently as about 200 AD. A swarm of earthquakes has hit the Salton Sea area. Past swarms in this area have remained active for 1 to 20 days, with a typical duration of about a week, so this swarm may have future bursts of activity that will in turn impact the probabilities discussed below. The Brawley Seismic Zone has been interpreted as an "onshore spreading center" which runs diagonally across the Salton Trough. Map showing the Salton Sea, CA earthquake swarm of August 2020 (as of August 11, 2020). "[This is] one of the largest swarms we have had in the Imperial Valley," seismologist Dr. Lucy Jones said. The largest earthquake that has occurred, as of this release, is a magnitude 4.6 at 8:56 AM PDT on August 10. No one can predict the exact time or place of any earthquake, including aftershocks or events in swarms. It is not known whether this is related to possible magmatic activity of the Newberry caldera. Between 11:03 UTC on September 26 and 06:03 UTC on September 27, 2016, USGS registered a total of 143 earthquakes in a remote desert area around the Salton Sea in California. Credit: TW/SAM, Google. The activity of previous swarms in this region spun from 1 to 20 days with the average being around one week. While this is a very small probability, if such an earthquake were to occur, it would have serious impacts on communities nearby and would be followed by aftershocks that would increase the number of smaller earthquakes per day. "This area has also seen swarms in the past – notably the 1981 Westmorland swarm, which included a M5.8 earthquake, and the 2012 Brawley swarm, which included a M5.4 earthquake. Past swarms in this area have remained active for 1 to 20 days, with a typical duration of about a week. Some additional moderately sized earthquakes (M4.5 to 5.4) may occur, which could cause localized damage, particularly in weak structures. Past swarms have remained active for 1 to 20 days, with an average duration of about a week. And today’s Salton Sea earthquake swarm raises the probability of larger earthquakes in the San Andreas region. The American Meteor Society (AMS) camera system captured a swarm of 7 bright meteors of unknown origin within just 3 seconds of one another at 11:50 UTC on January 18, 2021. When there are more earthquakes, the chance of a large earthquake is greater, which means that the chance of damage is greater. The Salton Sea is a shallow, landlocked body of water that has a high concentration of salts in Riverside and Imperial counties. This swarm may lead to larger and potentially damaging earthquakes in the future, so remember to: Drop, Cover, and Hold on if you feel shaking or receive a ShakeAlert message. An intense earthquake swarm started near Salton Sea, California on September 30, 2020, with 421 earthquakes detected by 07:00 UTC on October 1. The bolide was generated by a rock from an asteroid that hit the... A rock avalanche with an impressive runout pattern has been spotted at Mount Darwin in New Zealand on January 16, 2021. New activity/unrest: Kilauea, Hawaiian Islands (USA) | Langila, New Britain (Papua New Guinea) | Merapi, Central... A rhythmic pattern sounding like a low-frequency musical note was detected from the magnetosphere over Lofoten, Norway, on Monday, January 18, 2021. There were dozens of quakes over a 24 hour period in and around Ocotillo Wells in Imperial County, according to the LA Times. Scenario 3 (least likely): A much larger earthquake (magnitude 7 or higher) could occur within the next 7 days. WESTMORLAND, Calif. (KABC) -- An earthquake swarm continued Thursday in desert communities near the Salton Sea, which has a history of such seismic activity, and … Subscribe to our newsletter and have our news updates delivered to your inbox daily. During the same period, ongoing activity was reported for 15 volcanoes. (Public domain.). Explosions sent ash up to 7.5 km (24 600 feet) a.s.l., with eruptive cloud drifting 500 km (310 miles) W of the volcano. The Chief Executive of the Wonogiri District Disaster Management Agency, Bambang Hariyadi, said the waterspout swirled over the... Mongolia is in the grip of one of its most extreme winters on record, according to the International Federation of Red Cross and Red Crescent Societies (IFRC), with temperatures forecast to plunge to -50 °C (-58 °F). Now, these earthquake swarms in 2012 and more recently are not connected to magma moving under the area, but it just shows how geologically active this area is. The Salton Buttes on the south shore of the Salton Sea are on the north margin of the Brawley Seismic Zone and are linked to volcanic and geothermal activity within the zone. There was quite a bit of shaking in the Salton Sea area has a swarm of earthquakes – including six larger than a three magnitude – were reported on Sunday. We are pleased to report that the earthquake activity has returned to typical pre-swarm levels. Only one of these scenarios will occur within the next week. Map showing the Bombay Beach swarm of August 2020 (as of August 10, 2020). At 00:30 UTC on January 21, ash was rising about 3.7 km (12 000 feet) above sea level and drifting... New/activity unrest was reported for 7 volcanoes from January 13 to 19, 2021. The chance of large earthquakes will remain elevated as long as the swarm continues. This is compared to a peak of 54 earthquakes on August 10th, the day of the M4.6 mainshock, which remains the largest earthquake so far. Historically largest Brawley event was M5.8.". Interesting to note no new cases no new deaths in C, The image that appears on your comment is your Gravatar. The most notable earthquakes in the region include M5.8 in 1981 and M5.4 in 2012. Located on the San Andreas Fault at the southern end of the U.S. state of California, it lies within the Salton Trough that stretches to the Gulf of California in Mexico. Using the parallelized version of the code, we have detected many missing earthquakes in the Salton Sea geothermal field in southern California following the 2010 Mw7.2 El Mayor- Cucapah earthquake in Baja California, Mexico. A less likely scenario is a somewhat larger earthquake (up to a M6.9). Hundreds of earthquakes have rattled an area about 100 miles east of San Diego just southeast of the Salton Sea since Wednesday afternoon, suggesting more activity will shake the region over the next week including a quake up to a 5.4 magnitude, the U.S. Geological Survey said. A much less likely scenario, compared with the previous two scenarios, is that the ongoing swarm could trigger an earthquake significantly larger than the M4.6 that occurred on the 10 August (i.e., M7.0 and above). In a typical week, there is approximately a 1 in 10,000 chance of a magnitude 7+ earthquake on the southernmost San Andreas Fault. This area has also seen swarms in the past – most recently, in 2001, 2009, and 2016. Circles are earthquake locations, red indicates an earthquake in the past hour, orange the past 24 hours, and yellow the past 7 days. The severe cold has killed more than 500... A strong paroxysmal event took place at Klyuchevskoy volcano on January 18, 2021. These scenarios include the possibility of earthquakes on and off the San Andreas Fault. The southernmost section of the San Andreas Fault is capable of rupturing in large magnitude earthquakes (magnitude 7+), the last of which occurred more than 300 years ago. A less likely scenario is a somewhat larger earthquake (up to a M6.9). The object was seen for several seconds over wide areas of Japan, including Kanto, Tokai, and Kinki. In a typical week, there is approximately a 1 in 10,000 chance of a magnitude 7+ earthquake on the southernmost San Andreas Fault. A swarm of earthquake activity is hitting the Salton Buttes area down in Southern California. Fujii Daichi, a curator who specializes in astronomy at the... A newly-discovered asteroid designated 2021 BR2 flew past Earth at 0.19 LD / 0.00049 AU (73 300 km / 45 550 miles) from the center of our planet at 02:25 UTC on January 16, 2021. Map showing the Salton Sea, CA earthquake swarm of August 2020 (as of August 13, 2020 12pm Pacific). Nevertheless, as the USGS did with the August Salton Sea swarm, they’ve issued an earthquake forecast that breaks down the probability of whether these small earthquakes might lead to bigger ones. An intense earthquake swarm started near Salton Sea, California on September 30, 2020, with 421 earthquakes detected by 07:00 UTC on October 1. The earthquake swarm that began on August 10th continues to quiet down, producing only 1 earthquake of magnitude 2 and larger in the last 24 hours (as of noon August 13th). An strong earthquake swarm with hundreds of quakes up to magnitude 5 occurred during 26-28 August near the southern shore of Salton Lake, under the town of Brawley. When an region undergoes stretching, the crust begins to thin, allowing the more-buoyant (less-dense) mantle to begin to rise up and occupy the newly created space! In this paper, we describe how GPU computing is implemented and present initial results from our study. A much less likely scenario, compared with the previous two scenarios, is a much larger earthquake (i.e., M7.0 and above). The last eruption of this volcano took place in 1982 (VEI 5). Moderately sized earthquakes may occur (magnitude in the range M4.5-M5.4), which could cause localized damage, particularly in weak structures. The USGS is reporting M7.0 at a depth of 96 km (60 miles), EMSC M7.1 at... A bright fireball was seen and recorded over Japan at 11:32 UTC on January 20, 2021 (20:32 JST). Smaller magnitude earthquakes (M3.0+) may be felt by people close to the epicenters. Map via USGS. The southernmost section of the San Andreas Fault is capable of rupturing in large magnitude earthquakes (magnitude 7+), the last of which occurred more than 300 years ago. Help Support my Channel https://www.gofundme.com/f/support-real-thing-tv Signs of Activity on Happening Salton SeaSwarms of earthquakes and contaminated water For the next week, we estimate an elevated chance of such an earthquake to be less than 1 in 1,000. Scenario 1 (most likely): Earthquakes continue, possibly including earthquakes up to magnitude 5.4. Three of them had magnitudes above 4. The largest was a shallow M4.3 at 14:31 UTC on September 26. You can reach me at teo [ at ] watchers.news. Data source: USGS. Geographic Names Information System (GNIS), Mapping, Remote Sensing, and Geospatial Data, magnitude 4.6 at 8:56 AM PDT on August 10. "This earthquake [M4.9] and the associated swarm are located in an area of diffuse seismic activity between the San Andreas fault in the north and the Imperial fault to the south," USGS seismologists said in a statement. The USGS registered a total of 440 earthquakes from 10:06 UTC on September 30 to 07:33 UTC on October 1, 2020, with the largest M4.9 at 00:31 UTC on October 1, followed by M4.5, M4.4, M4.2, and two M4.1. Remember, it's free and you can unsubscribe at any time! 3. One uncertain aspect of this swarm is how long the elevated earthquake activity will last. EARTHQUAKE SWARM: At least 240 small earthquakes, the largest measuring 4.9, shook desert communities near the Salton Sea Wednesday. These scenarios include the possibility of earthquakes on and off the Imperial and San Andreas Faults. It hit 6 km (3.7 miles) SSE of Bombay Beach, 19 km (11.8 miles) WNW of Niland and 23 km (14.3 miles) E of … The most likely scenario is that the rate of earthquakes in the swarm will decrease over the next 7 days. A much less likely scenario, compared with the previous two scenarios, is that the ongoing swarm could trigger an earthquake significantly larger than the M4.9 that occurred on September 30 (i.e., M7.0 and above). Our updated probabilities for the following three scenarios reflect this reduction in activity; however, the risk of a large earthquake remains elevated due to the swarm when compared to background levels. During the last swarm in 2016, there were three bursts of activity separated by relatively quiet periods before the swarm ended. Circles are earthquake locations, red indicates an earthquake in the past hour, orange the past 24 hours, and yellow the past 7 days. Our earthquake forecasts give us an understanding of the chances of having more earthquakes within a given time period in the affected area. Also consider that Salton Sea is part of the rifting region that is separating Baja California from the rest of Mexico (creating the Gulf of California). Tropical Cyclone "Eloise" is moving WSW over the Mozambique Channel, towards the central coast of Mozambique. In a typical week, there is approximately a 1 in 10,000 chance of a magnitude 7+ earthquake on the southernmost San Andreas Fault. Earthquakes of this size could cause damage around the Salton Sea area and would be followed by additional aftershocks. The swarm happening now south of the Salton Sea, near Westmoreland is over 30 km south of the end of the San Andreas. According to Yury Demianchuk from Russia's volcanological... Mexico's National Seismological Service (SSN) has registered a total of 22 earthquakes within 35 km (22 miles) of El Chichon (El Chichonal) volcano from December 24, 2020, to January 19, 2021.
