Mount Pelée on Martinique has shown renewed unrest, with 124 earthquakes between July 24–31 and 331 for the month, plus ground deformation near the summit; scientists have raised the alert to yellow and caution that while the short-term eruption probability is low, a future eruption cannot be ruled out and could threaten Martinique’s 400,000 residents, recalling the 1902 eruption that killed about 30,000.
During the USA men’s World Cup match against Australia in Seattle, fans’ cheers triggered actual ground movement at Lumen Field, with the Pacific Northwest Seismic Network recording spikes on nearby seismometers as the U.S. took a 2-0 lead, a moment recalled alongside Marshawn Lynch’s famous “Beast Quake.”
A preliminary magnitude 7.3 earthquake struck near Vanuatu in the South Pacific Ocean, with the update timestamp noted; the excerpt does not provide details on damage or casualties.
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.
