Drilling into the mysteries of seismic activity

An international expedition aims to better understand seismic activity through samples collected from one of the most geologically active areas in Europe. More than 30...

Database eyes human role in earthquakes

A new database showcasing hundreds of examples of human-triggered earthquakes should shake up policy-makers, regulators and industry executives looking to mitigate these unacceptable hazards...

2011 Tohoku-oki earthquake: Results from seismic reflection data

A striking finding of the 2011 Tohoku-oki earthquake (Mw 9.0) is that more than 50 meters of coseismic fault slip reached the trench axis....

Researchers produce new map of seismic hazards in Brazil

Researchers are working on a new national map of seismic hazards for Brazil. In preparing the seismic hazard map, the researchers first conducted a...

Study details evidence for past large earthquakes in the Eastern Tennessee...

The Eastern Tennessee Seismic Zone (ETSZ), a zone of small earthquakes stretching from northeastern Alabama to southwestern Virginia, may have generated earthquakes of magnitude...

Hydraulic fracturing rarely linked to felt seismic tremors

New research suggests hydraulic fracturing and saltwater disposal has limited impact on seismic events. For the past two years, UAlberta geophysicist Mirko Van der Baan...

A seismic mapping milestone

Because of Earth's layered composition, scientists have often compared the basic arrangement of its interior to that of an onion. There's the familiar thin...

Release of water shakes Pacific Plate at depth

Tonga is a seismologists' paradise, and not just because of the white-sand beaches. The subduction zone off the east coast of the archipelago racks...

Seismically active Katmandu region in store for larger earthquake

An earthquake much more powerful and damaging than last year's 7.8 magnitude quake could rock Katmandu and the Himalayan Frontal Fault, an international team...

Fault curvature may control where big earthquakes occur

Major earthquakes -- magnitude 8.5 and stronger -- occur where faults are mostly flat, say University of Oregon and French geologists. Curvier faults, they...
