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...

Japan, Taiwan and New Zealand collaborate on seismic hazard models

In Japan, Taiwan and New Zealand, one of the largest driving forces behind earthquakes is the active convergence of tectonic plates at rates of...

Seismometers are giving scientists a clearer look at a giant scar...

When Doug Wiens approached Minnesota farmers to ask permission to install a seismometer on their land, he often got a puzzled look. "You could...

Seismic ‘CT scans’ reveal deep earth dynamics

A new look 100 miles beneath a massive tectonic plate as it dives under North America has helped clarify the subduction process that generates...

Japan scientists detect rare, deep-Earth tremor

Scientists who study earthquakes in Japan said Thursday they have detected a rare deep-Earth tremor for the first time and traced its location to...

Electrical conductivity of salt water in seismogenic zones theoretically determined

A joint research team consisting of Hiroshi Sakuma, senior researcher, Functional Geomaterials Group, Environment and Energy Materials Division, National Institute for Materials Science (NIMS),...
