Pair of seismologists publicly wonder if it might be possible to predict largest earthquakes
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. ...
Great Alaska Earthquake shook Alaska 50 years ago
Electric clocks on walls in Anchorage shut down at 5:36 p.m. on March 27, 1964. Time stopped at the start of the '64 Great Alaska Earthquake, the second largest ever recorded at magnitude 9.2.
Subduction zones reveal sulphur cycle and mineral potential
Reasearch led by West Australian scientists into 'subduction' during tectonic plate collisions has provided new insights into the global sulphur cycle.
Systematic shifts in subducting slab behavior with depth
When tectonic plates collide, the less buoyant plate will, in some cases, be forced beneath the other. At such subduction zones the sinking tectonic plate, known as a slab, does not follow a simple path from the surface to ...
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.
Global map to predict giant earthquakes
A team of international researchers, led by Monash University's Associate Professor Wouter Schellart, have developed a new global map of subduction zones, illustrating which ones are predicted to be capable of generating ...
Understanding the forces that shape the Earth
Subduction is the process occurring where the Earth's tectonic plates meet - and one plate slides beneath the other, taking surface material to its interior. This process leads to a large variety of phenomena ...
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 ...
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.
