Pair of seismologists publicly wonder if it might be possible to predict largest earthquakes
New model of Earth's interior reveals clues to hotspot volcanoes
Scientists at the University of California, Berkeley, have detected previously unknown channels of slow-moving seismic waves in Earth's upper mantle, a discovery that helps explain "hotspot volcanoes" that ...
Distant quakes trigger tremors at US waste-injection sites, says study
Large earthquakes from distant parts of the globe are setting off tremors around waste-fluid injection wells in the central United States, says a new study. Furthermore, such triggering of minor quakes by ...
Scientists find odd twist in slow 'earthquakes': Tremor running backwards
Earthquake scientists trying to unravel the mysteries of an unfelt, weeks-long seismic phenomenon called episodic tremor and slip have discovered a strange twist. The tremor can suddenly reverse direction ...
Geophysicists claim conventional understanding of Earth's deep water cycle needs revision
A popular view among geophysicists is that large amounts of water are carried from the oceans to the deep mantle in "subduction zones," which are boundaries where the Earth's crustal plates converge, with ...
Shaking the Earth: How Water Helps Tectonic Plates Slide in New Zealand
(PhysOrg.com) -- New Zealand is the site of one of the world’s youngest subduction zones, where the Pacific Plate of Earth’s crust dives beneath the Australian Plate. Now, a University of Utah study shows ...
In Mediterranean marble, secrets of the global carbon cycle
(Phys.org) —Scientists at Yale University have clarified how carbon dioxide escapes minerals deep inside Earth and seeps into the planet's atmosphere, a significant step in the planet's natural carbon cycle. ...
Is there an ocean beneath our feet?
(Phys.org) —Scientists at the University of Liverpool have shown that deep sea fault zones could transport much larger amounts of water from the Earth's oceans to the upper mantle than previously thought.
Vancouver: Nearby Georgia basin may amplify ground shaking from next quake
Tall buildings, bridges and other long-period structures in Greater Vancouver may experience greater shaking from large (M 6.8 +) earthquakes than previously thought due to the amplification of surface waves ...
Does a planet need life to create continents?
If not for life, Earth may not have possessed the continents it does now, instead becoming a planet covered nearly entirely in ocean, researchers say.
Scientists anticipated size and location of 2012 Costa Rica earthquake
Scientists using GPS to study changes in the Earth's shape accurately forecasted the size and location of the magnitude 7.6 Nicoya earthquake that occurred in 2012 in Costa Rica.
Mega-quakes caused volcanoes to sink, research finds
Massive earthquakes can cause distant volcanoes to sink, according to research in Japan and Chile published on Sunday.
New 'embryonic' subduction zone found
(Phys.org) —A new subduction zone forming off the coast of Portugal heralds the beginning of a cycle that will see the Atlantic Ocean close as continental Europe moves closer to America.
Earthquake acoustics offer hint that a tsunami is imminent, researchers find
(Phys.org) —On March 11, 2011, a magnitude 9.0 undersea earthquake occurred 43 miles off the shore of Japan. The earthquake generated an unexpectedly massive tsunami that washed over eastern Japan roughly 30 minutes later, ...
