A strong magnitude 6.8 earthquake occurred near Yamada, Japan, on November 9, 2025, with light to moderate shaking felt in the region, but it is not expected to cause significant damage or fatalities, and the risk level is low.
A strong magnitude 6.0 earthquake occurred in the Philippine Sea near Tandag, Philippines, at a depth of 59 km, felt by numerous people with minimal risk of casualties or significant damage, and an alert level of green indicating low danger.
A magnitude 6.4 earthquake struck near Molina, Chile, at a depth of 111 km, causing moderate shaking in nearby areas including Talca and Curico. The quake was felt by over 7.5 million people across Chile and Argentina, but due to its depth, significant damage is unlikely. The US Geological Survey has issued a green alert, indicating a low risk of casualties and economic losses.
India's Chandrayaan-3 mission has detected unexpected subsurface movement at the moon's South Pole using the Pragyan rover's Instrument for Lunar Seismic Activity (ILSA). This discovery, recorded on August 25 and 26, 2023, suggests potential geological activity beneath the moon's surface, raising questions about its dynamics. The movements could be due to natural lunar quakes or impact-related shifts, and ISRO is investigating these unusual vibrations to understand their origins.
A magnitude-4.2 earthquake struck the San Bernardino County community of Lytle Creek in the mountains east of Los Angeles, causing widespread shaking across Southern California, including Long Beach, the San Fernando Valley, Riverside, and Orange County. There were no immediate reports of damage or injuries. The quake occurred near the convergence of the San Andreas and San Jacinto faults, an area with a history of seismic activity.
Southern California experienced a 4.1-magnitude earthquake with its epicenter north of Rancho Cucamonga in the San Gabriel Mountains, felt across various parts of the region including Los Angeles County. Initially reported as a 4.6-magnitude quake, it was downgraded and resulted in no immediate reports of injuries or damage. The area is known for seismic activity, with this being the second earthquake above magnitude 4.0 in the region since the start of the year.
Southern California experienced a 4.2 magnitude earthquake with its epicenter near Lytle Creek, north of San Bernardino. The tremor occurred on Friday morning with no reported injuries or significant damage in Los Angeles or San Bernardino County. This event follows a 4.1 magnitude quake earlier in the week off the coast near Rancho Palos Verdes. Local authorities have not reported any calls for service related to the earthquake.
A 4.1 magnitude earthquake hit the Lytle Creek area in California, with its epicenter at the Cajon Pass, a location known for seismic activity due to the convergence of the San Andreas and San Jacinto faults. Initially reported as a 4.6 magnitude quake, it was later downgraded by the USGS. Residents across various cities felt the tremor, but there were no immediate reports of injuries or significant damage. The event has prompted reminders about the importance of having an earthquake kit prepared.
The fishing town of Wajima, Japan, has been severely affected by the country's most powerful earthquake in 12 years, resulting in fires, destruction of homes, and at least 73 fatalities. Rescue efforts are being hampered by damaged infrastructure, with sniffer dogs searching through the debris for survivors. The quake has caused widespread damage across the Noto Peninsula, with many areas isolated and in need of aid. Prime Minister Fumio Kishida has announced an increase in military and rescue personnel to assist in relief efforts. The earthquake has reignited fears of seismic activity in a region that has experienced numerous tremors in recent years.
A minor 1.7-magnitude earthquake struck near Astoria in Queens, NYC, coinciding with reports of small explosions on Roosevelt Island, which officials suspect were caused by the quake. No injuries or damage were reported. Earlier, a 2.3-magnitude earthquake occurred near Rockville, Maryland, felt across several states. While less common than in the west, East Coast earthquakes can affect larger areas due to older, denser rocks that transmit seismic waves more efficiently.
Early Tuesday, a minor 1.7 magnitude earthquake struck under Astoria, Queens, causing confusion and concern on Roosevelt Island as residents mistook the tremor for an explosion. The quake led to a significant FDNY response, but no damage, injuries, or power outages were reported. This event was notable as earthquakes are rare in New York City, with this being only the eighth since 1970. The USGS clarified that the unusual nature of the event for locals likely contributed to the initial confusion.
A 1.7 magnitude earthquake centered near Astoria, Queens in New York City was felt early Tuesday morning, causing residents in parts of NYC and several areas of northern New Jersey to experience weak shaking. The tremor, which occurred around 5:45 a.m., also led to power outages in some areas and was reported as far away as Connecticut and Maine. Despite being a minor quake, it was enough to jolt some residents awake with what felt like an explosion.
A 2.3-magnitude earthquake struck near Rockville, Maryland, in the early hours of Tuesday, with residents reporting sounds and vibrations akin to a heavy truck passing or a low roar. The quake was minor, with no damage or injuries reported, but it was widely felt in Montgomery County and parts of Northern Virginia and D.C. The USGS received over 850 reports within an hour of the event, highlighting the community's surprise and uncertainty regarding the unusual seismic activity.
