This Simulation Shows What Would Happen If an Earthquake Caused a Mega-Tsunami
The
last megathrust earthquake that created an ocean-crossing tsunami was
recorded along the 600-mile-long fault of the Cascadia Subduction Zone
in the Northwest on January 26 in 1700. In fact, on Friday, the Pacific
Tsunami Warning Center published a re-enactment of the massive waves in a
model animation. Such an earthquake would have ruptured the earth along
the entire length of the 1000 km (600 mi)-long fault of the Cascadia
Subduction Zone and severe shaking could have lasted for 5 minutes or
longer. Its tsunami would cross the Pacific Ocean and reach Japan in
about 9 hours, so the earthquake must have occurred around 9 o'clock at
night in Cascadia on January 26, 1700 (05:00 January 27 UTC).
