Rumbling from ocean trenches could be sign that Japan faces mega earthquake
Researchers in Japan have for the first time detected and traced shallow tremors under the ocean that could be a sign that the country is heading towards a huge earthquake. But the technique itself may one day ...
Seafloor sensors record possible eruption of underwater volcano
If a volcano erupts at the bottom of the sea, does anybody see it? If that volcano is Axial Seamount, about 300 miles offshore and 1 mile deep, the answer is now: yes.
Can sound help us detect 'earthquakes' on Venus?
Detecting an "earthquake" on Venus would seem to be an impossible task. The planet's surface is a hostile zone of crushing pressure and scorching temperatures—about 874 degrees F, hot enough to melt lead—that ...
The 2011 Tohoku-Oki earthquake—felt from space
For the first time, a natural source of infrasonic waves of Earth has been measured directly from space—450 kilometers above the planet's surface. The source was the massive 2011 Tohoku-Oki earthquake in ...
Seismic study aims to map Earth's interior in 3-D
When a 7.9-magnitude earthquake struck central China's Sichuan province in 2008, seismic waves rippled through the region, toppling apartment houses in the city of Chengdu and swaying office buildings 1,000 ...
Fracking confirmed as cause of rare 'felt' earthquake in Ohio
A new study links the March 2014 earthquakes in Poland Township, Ohio to hydraulic fracturing that activated a previously unknown fault. The induced seismic sequence included a rare felt earthquake of magnitude ...
Volcano in south Japan erupts, disrupting flights
A volcano in southern Japan is blasting out chunks of magma in the first such eruption in 22 years, causing flight cancellations and prompting warnings to stay away from its crater.
Japan police: Volcanic rocks killed most victims
Doctors have determined that almost all of the dozens of people killed on a Japanese volcano died of injuries from being hit by rocks that flew out during its eruption, police said Thursday.
New tremors raise concern at Japan's Mount Ontake
Increased seismic activity raised concern Tuesday about the possibility of another eruption at a Japanese volcano where 36 people were killed, forcing rescuers to suspend plans to try to recover at least ...
Tourists evacuated amid Iceland volcano concerns
Authorities have evacuated tourists from an area north of Iceland's largest glacier amid increased seismic activity around a volcano in the past few days.
Network for tracking earthquakes exposes glacier activity
Alaska's seismic network records thousands of quakes produced by glaciers, capturing valuable data that scientists could use to better understand their behavior, but instead their seismic signals are set aside as oddities. ...
Dynamic stressing of a global system of faults results in rare seismic silence
In the global aftershock zone that followed the major April 2012 Indian Ocean earthquake, seismologists noticed an unusual pattern – a dynamic "stress shadow," or period of seismic silence when some faults near failure ...
Seismic activity felt on Spanish volcanic island
Spain's National Geographical Institute says the Canary Island of El Hierro has been rocked by more than 50 tremors in 24 hours, two years after a new volcano began to appear off its southern coast.
Spain sees 'limited risk' of big quake linked to gas
Spain's government said Friday there is a limited risk of a big earthquake shaking the eastern coast after a string of small tremors linked to a vast offshore gas storage plant.
