Japan quake felt in Virginia water well

The big earthquake this morning in Japan sent seismic waves around the planet, and, as so often happens with big quakes, those waves triggered a reacting in an especially quake-sensitive monitoring well in Christiansburg, Va. Take a look at the seismic tracing below.

The quake caused the 2.5-foot rise and fall in the water level in the USGS well, visible in the blue spike on the right. And sizable tremors continue to rattle the epicenter off the coast on Honshu.
