Magnitude 6.3 – Central Italy – April 6, 2009

April 21, 2009

The BC-ESP recorded the devastating magnitude 6.3 earthquake that occurred in Central Italy on April 6th at 01:32:42 UTC. Although this earthquake was very destructive, magnitude 6.3 is too small for us to get a strong recording here in the Boston area from an earthquake in Italy. However, you can still see a small signal of the quake here (see arrow on seismogram).
