An M7.7 earthquake struck near Mandalay, Myanmar, on March 28, 2025, killing more than 5 000 people and injuring at least 11 400. The shallow, high-magnitude event ruptured a long section of the Sagaing Fault, prompting seismologists to investigate its complex rupture dynamics and evidence of supershear propagation.
M5.2 earthquake that struck San Diego County near Julian on April 14, 2025, occurred along the Elsinore Fault Zone, a major strike-slip fault in Southern California capable of producing earthquakes up to magnitude 7.8. The fault runs near densely populated areas including Los Angeles, Long Beach, and Riverside, and its long period of limited activity may indicate an increased potential for a significant seismic event, according to recent research.
A shallow earthquake registered by the USGS as M6.6 hit the southeast Indian Ridge at 01:42 UTC on April 16, 2025. The agency is reporting a depth of 10 km (6.2 miles).
Researchers at the 10th Delphi Economic Forum on April 13, 2025, revealed that the use of advanced machine learning technology enabled them to detect over 50 000 earthquakes in Santorini, some of which occurred before the intense earthquake swarm in February 2025. This early detection enhanced earthquake forecasting and improved warning procedures during the crisis.
A shallow earthquake registered by the USGS as M5.2 struck near Julian, San Diego County, at 17:08 UTC (10:08 local time) on April 14, 2025, shaking large areas of Southern California. The agency reports a depth of 14.3 km (9 miles).
A deep earthquake registered by the USGS as M6.5 hit south of Fiji Islands at 20:03 UTC on April 13, 2025. The agency is reporting a depth of 270 km (168 miles). EMSC is reporting M6.5 at a depth of 262 km (163 miles).
A strong earthquake registered by the USGS as M6.1 struck near the New Ireland Region, Papua New Guinea, at 03:47 UTC (13:47 local time) on April 12, 2025. The agency is reporting a depth of 62 km (38 miles). ESMC is reporting the same depth and magnitude.
A very strong earthquake registered by the USGS as M6.9 hit New Britain region of Papua New Guinea at 20:05 UTC on April 4, 2025 (06:05 LT, April 5). The agency is reporting a depth of 10 km (6.2 miles). EMSC is reporting the same magnitude and depth.
A strong and shallow earthquake registered by the USGS as M6.9 hit Reykjanes Ridge, Atlantic Ocean at 14:09 UTC on April 3, 2025. The agency is reporting a depth of 10 km (6.2 miles). EMSC is reporting M6.8 at a depth of 7 km (4.3 miles).
A strong earthquake registered by the Japan Meteorological Agency (JMA) as M6.0 struck off the east coast of Osumi Peninsula, Kyushu at around 23:04 JST (14:04 UTC) on April 2, 2025. The USGS is reporting M6.2 at a depth of 26 km (16 miles).
