Puerto Rico tsunami deposit could have come from pre-Columbian megathrust earthquake
Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench that occurred between 1470 and 1530, according to research reported at the Seismological Society of.....»»
Japan"s "megaquake" warning explained
Japan's earthquake scientists say the country should prepare for a possible "megaquake" one day that could kill hundreds of thousands of people—although they stress the warning does not mean a colossal tremor is imminent......»»

Sichuan Province earthquake offers lessons for landslide prediction from GNSS observations
Using data collected from a 2022 magnitude 6.8 earthquake in Luding County in China's Sichuan Province, researchers have tested whether Global Navigation Satellite System (GNSS) observations could be used for rapid prediction of earthquake-triggered.....»»
Mantle upwelling may have triggered Morocco earthquake
On 8 September 2023, a magnitude 6.8 earthquake struck western Morocco, causing damage and destruction that claimed thousands of lives in rural communities in the High Atlas Mountains......»»
Tsunami sands help scientists assess Cascadia earthquake models
To better understand the scale of past earthquakes and tsunamis, scientists often use earthquake modeling or turn to evidence the tsunamis leave behind, such as sand deposits......»»
Tonga"s volcanic eruption could cause unusual weather for the rest of the decade, new study shows
Hunga Tonga-Hunga Ha'apai (Hunga Tonga for short) erupted on January 15 2022 in the Pacific Kingdom of Tonga. It created a tsunami which triggered warnings across the entire Pacific basin, and sent sound waves around the globe multiple times......»»
Researchers unveil the mechanisms for local amplification of 2024 tsunamis in Iida Bay, Japan
In 2024, a 7.5 magnitude earthquake struck the Noto Peninsula in Japan on New Year's Day, causing strong shaking, landslides, fire, liquefaction, land uplift, and devastating tsunamis. Ishikawa Prefecture, the hardest hit area, saw at least 241 fatal.....»»
"Dusty" archives inspire new story about 1886 Charleston earthquake
Late on August 31, 1886, while many people were asleep, a large quake rocked Charleston, South Carolina, and the surrounding region, toppling buildings, buckling railroad tracks, and causing sand to "boil" or bubble from liquefaction. By the time the.....»»
Improving the effectiveness of earthquake early warning systems
Mobile phones have become invaluable for receiving emergency alerts such as weather warnings, evacuation notices and notifications about missing persons. In Japan, where earthquakes are frequent, they are vital for delivering earthquake warnings and.....»»
Study demonstrates self-similar fractal stress is more suitable for destructive scenario earthquake simulation
Scenario earthquakes are useful in assessing earthquake hazards along active faults. However, determining the sources of destructive scenario earthquakes, particularly when dealing with heterogeneous stresses, can be challenging......»»
Study suggests heavy snowfall and rain may contribute to some earthquakes
When scientists look for an earthquake's cause, their search often starts underground. As centuries of seismic studies have made clear, it's the collision of tectonic plates and the movement of subsurface faults and fissures that primarily trigger a.....»»
