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...

New map shows where fracking-induced earthquakes could hit in Canada

Scientists from the University of Waterloo have developed a map showing which regions and population centers of Western Canada are likely to experience earthquakes...

Earthquake shakes Ecuador’s coast, teen killed by power line

An earthquake of preliminary magnitude 5.7 shook Ecuador's coast Thursday, causing one death when a teenager was electrocuted by a fallen power line, authorities...
