New Animation!  “Japan: Overview of Earthquakes & Tectonics”

Japan has more measurable earthquakes than any other country and has over 100 active volcanoes. The tectonics are complicated, but in this animation we look at the basic mechanics of the region as we focus on two famous earthquakes: the 1995 Kobe earthquake and the 2011 Tohoku-Oki earthquake.
