EARTHQUAKES

6.8 magnitude earthquake shakes Mexico, 1 dead

A powerful earthquake with a preliminary magnitude of 6.8 struck Mexico early Thursday, causing buildings to sway and leaving at least one person dead...

Strong earthquakes shake part of Indonesia’s West Papua

A series of strong inland earthquakes shook Indonesia's easternmost province Saturday, but there were no immediate reports of serious damage or casualties. The Indonesian Meteorology,...

Months of gravity changes preceded the Tōhoku earthquake

Earthquakes caused by subducting tectonic plates can be highly destructive events. The 2011 Tōhoku earthquake caused immense damage to population centers in eastern Japan. Constant...

Hidden microearthquakes illuminate large earthquake-hosting faults in Oklahoma and Kansas

Using machine learning to sift through a decade's worth of seismic data, researchers have identified hundreds of thousands of microearthquakes along some previously unknown...

A swarm of 85,000 earthquakes at the Antarctic Orca submarine volcano

Volcanoes can be found even off the coast of Antarctica. At the deep-sea volcano Orca, which has been inactive for a long time, a...

Magnitude 5.7 earthquake shakes part of eastern Indonesia

An undersea earthquake shook part of eastern Indonesia on Sunday, but there were no immediate reports of serious damage or casualties. The U.S. Geological Survey...

New ground motion model more accurately simulates earthquakes, explosions

Lawrence Livermore National Laboratory (LLNL) scientists have created a new adjoint waveform tomography model that more accurately simulates earthquake and explosion ground motions. The...

Deep earthquakes suggest well-hydrated Mariana subduction zone

On the surface, subduction zones manifest as oceanic trenches, the deepest of which is the Mariana Trench in the Pacific Ocean. One notable feature...

Nanoscale observations simplify how scientists describe earthquake movement

Using single calcite crystals with varying surface roughness allows engineers to simplify the complex physics that describes fault movement. In a new study from...

Balloon fleet senses earthquakes from stratosphere

A new study in AGU's Geophysical Research Letters reports on the first detection of a large, distant earthquake in a network of balloon-bound pressure sensors in...

The physics of snow slab avalanches similar to that of earthquakes

Scientists from EPFL and the WSL Institute for Snow and Avalanche Research SLF have gained deeper insight into how snow slab avalanches form, paving...

Strong quake kills 4, injures dozens in northern Philippines

A strong earthquake set off landslides and damaged buildings in the northern Philippines in Wednesday, killing at least four people and injuring dozens. In...
