Another Quake!

Posted by Dan Satterfield

Sumatra was hit by a magnitude 7.7 quake at 10:18 GMT this Wednesday morning. This quake was on a different fault zone and was likely not related to yesterday’s quake in Samoa.

Here is a seismogram from Washington State in the USA. The seismograph picked up the quake from half a world away.
