A series of strong earthquakes, including a magnitude 6.2 quake, struck western Japan's Shimane and Tottori prefectures, causing widespread shaking, power outages, and train delays, but no tsunami threat or nuclear plant damage has been reported.
A 6.5 magnitude earthquake struck southern and central Mexico, particularly near Acapulco and Mexico City, causing at least two deaths, injuries, and some landslides, but no major damage was reported.
A magnitude 6.5 earthquake struck southern and central Mexico near Guerrero, causing landslides and prompting residents and tourists to evacuate, but no serious damage was reported according to officials.
A magnitude 6.5 earthquake struck southern and central Mexico near Guerrero, causing landslides and prompting residents to evacuate, but initial reports indicate no serious damage.
A magnitude 4.7 earthquake shook Northern California near Susanville, causing moderate shaking locally and light shaking as far as Sacramento and Klamath Falls, with no reports of damage. The quake occurred at a depth of 3.4 miles and was part of the region's typical seismic activity.
A series of three earthquakes with magnitudes of 3.9, 2.8, and 3.0 struck San Ramon in the Bay Area on Saturday evening, felt in Oakland and San Francisco, but caused no injuries or damages. This follows a recent cluster of seismic activity in the area earlier in the week.
San Ramon experienced a series of at least nine earthquakes, with the largest being a 4.0 magnitude, due to complex fault interactions and fluid infiltration in the area, which has been hit by nearly 150 quakes in the past month.
A series of at least six earthquakes, including a magnitude 4.0 quake, struck the San Ramon area on Friday night, causing local alarm but no damage. The seismic activity is part of a larger swarm that has been ongoing for days, with experts noting that such swarms are usually not indicative of an imminent larger quake and are often caused by fluid interactions or slow fault slipping.
A 6.3-magnitude earthquake struck southeastern Afghanistan near Mazar-i-Sharif, with the USGS monitoring potential aftershocks and updating data as available.
A powerful 7.4-magnitude earthquake struck off the coast of Mindanao in southern Philippines, with the extent of damage still unclear.
Two powerful earthquakes with magnitudes of 7.4 and 6.7 struck off southern Philippines, causing at least six deaths, injuries, and damage, while triggering temporary tsunami warnings that were later lifted. The region experienced significant shaking, building damage, and evacuations, highlighting the Philippines' vulnerability to seismic activity on the Pacific Ring of Fire.
The 2025 volcanic crisis at Santorini and Kolumbo revealed a coupled magma system with a significant dike intrusion and seismic swarm, indicating complex interactions between the volcanoes' magmatic and tectonic systems, emphasizing the importance of integrated real-time monitoring for hazard assessment.
Scientists have identified and dated 245 recent boulder falls on the moon, revealing ongoing geological activity and challenging the belief that the moon is geologically dead. They used high-resolution images and impact ejecta analysis to determine the age of these events, which are linked to seismic faults and impact sites, providing new insights into lunar surface dynamics.
Europe's Campi Flegrei caldera, a supervolcano near Naples, has experienced increased seismic activity over the past two years, with thousands of tremors detected. However, recent AI analysis indicates that these quakes are shallow, localized, and not associated with magma movement, suggesting no imminent eruption is likely. The volcano remains monitored, but current data do not point to an impending disaster.
In September 2023, a mysterious, prolonged seismic signal was detected worldwide, caused by a massive landslide in Greenland's Dickson Fjord triggered by climate change-induced glacial melting, which generated a 200-meter-high tsunami and a unique seiche wave that traveled globally for nine days, highlighting complex climate and geological interactions.
