Deep mission: Japan takes aim at the source of megaquakes

Even in port, it's easy to see how the research vessel Chikyu got its nickname. From the waterline to the top of its drilling derrick, the vessel also known as "Godzilla-Maru" towers nearly 30 stories tall.

Researchers find evidence of super-fast deep earthquake

As scientists learn more about earthquakes that rupture at fault zones near the planet's surface—and the mechanisms that trigger them—an even more intriguing earthquake mystery lies deeper in the planet.

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.

Scientists calculate friction of Japan's 9.0 earthquake in 2011

An international team of scientists that installed a borehole temperature observatory following the 2011 Tohoku-Oki earthquake in Japan has been able to measure the "frictional heat" generated during the rupture of the fault ...

Slow earthquakes may foretell larger events

Monitoring slow earthquakes may provide a basis for reliable prediction in areas where slow quakes trigger normal earthquakes, according to Penn State geoscientists.
