It is theoretically possible that the world could see a quake with a magnitude of around 10, a researcher at Tohoku University told the government’s Coordinating Committee for Earthquake Prediction, Japan. […]
“The estimate does not mean that a magnitude 10 quake will inevitably happen,” said Toru Matsuzawa, a professor at [Tohoku] university’s Research Center for Prediction of Earthquakes and Volcanic Eruptions. “If it happens, it would take place around once every 10,000 years.” […]
A magnitude 10 quake would likely cause ground motions for up to an hour, with tsunami hitting while the shaking was still going on, according to the research. Tsunami would continue for several days, causing damage to several Pacific Rim nations.
