On December 7, 2012, at 6:18pm Japanese Time, a magnitude 7.3 earthquake struck 152 miles southeast of Kamaishi, Japan. Seismic Strength 5- was recorded in Aomori, Iwate, and Miyagi Prefectures. Luckily, the epicenter was so far from the coast, that the shaking strength was far weaker than if the epicenter was nearer to shore.
The Earthquake Early Warning System warned people in Tokyo, over 72 seconds in advance of strong shaking. This amount of warning is similar to that of a possible warning time to the city of Los Angeles in the event of a large earthquake on the San Andreas Fault. How would you respond to such a warning?
A video of the multiple online warning systems in Japan, as well as an webcam video of the earthquake can be seen above.
