Seismic Network Sees Nepal Quake Waves Cross U.S.

world_eventsby WBOC Chief Meteorologist Dan Satterfield

A big hat tip to IRIS and my friend Seismologist John Taber for this. Keep in mind that the shortest distance to Nepal from the U.S. is over the North Pole, so the seismic waves come from that direction.

 

From IRIS: IRIS Ground Motion Visualization for the M7.9 earthquake in Nepal April 15, 2015. The visualization shows EarthScope seismic stations picking up the seismic waves generated from the earthquake. Red stations mean the station is moving up vertically and blue means the station is moving down vertically. Teachers the IRIS site has great materials for teaching your students about earthquakes and geology. New material regarding the Nepal quake is now available here
