Powerful earthquakes that have jolted Asia recently do not presage a disaster, although it is only a matter of time before the next catastrophe befalls the quake-prone region, seismologists say.

In 1923, a magnitude 7.9 earthquake devastated the Tokyo area, resulting in more than 100,000 deaths. About 200 years earlier, in 1703, a magnitude 8.2 earthquake struck the same region, causing more than 10,000 deaths.

The 11 March 2011 Tohoku-Oki earthquake was the largest and most destructive in the history of Japan. Japanese researchers—and their Norwegian partners—are hard at work trying to understand just what made it so devastating.

While metamorphic reactions in subducting slabs liberate large amounts of fluids, low-frequency earthquakes (LFE) largely occur beneath the impermeable, un-metamorphosed overlying plate, and are rarely found beneath metamorphosed ...

Megathrust earthquakes are the most powerful type of earthquake, occurring at subduction zones where one tectonic plate is pushed beneath another. By contrast, slow slip events (SSEs) release seismic stress at a lower rate ...
