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...

Geophysicist Helps Develop High-Res Map of Earth’s Magnetic Field

A University of Kentucky geophysicist is helping an international team of scientists reveal dramatic new information about the Earth's magnetic field. Two years ago, Dhananjay...

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...

Old rocks, biased data: Overcoming challenges studying the geodynamo

Gleaning data from old rocks may result in bias. Now, geophysicists have a way to improve their methods to overcome challenges in studying the...

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...

Seismologists warn of more quakes in New Zealand

Seismologists in New Zealand said Friday that this week's 7.8 earthquake was one of the most complex ever recorded and warned there was a...

Study reveals two seismic processes by which hydraulic fracturing induces tremors

In some parts of western Canada, small-to-moderate earthquakes have been induced by oil and gas hydraulic fracturing operations. In Alberta, this type of induced...
