Today we had an earthquake with magnitude M 6.3 in the Gulf of California (GOC). The GOC is formed by transtension (extension along a strike-slip fault system) along the North-America-Pacific plate boundary. Transtension happens when the plate motion across a…

There was an earthquake in Burma today! The epicenter plotted very close to the Sagaing fault (SF), a major dextral (right-lateral) strike-slip fault system, part of the plate boundary between the India and Eurasia plates. This fault system accommodates much…

Earthquake Report: Caroline Ridge Update #1

Posted on: December 9, 2017 Last updated on: December 9, 2017 Written by: Jay Patton Comments: 0
Well, there was an earthquake this morning (my time) that may help us select a fault plane solution. Recall that these fault plane solutions (moment tensors and focal mechanisms) have two possible fault planes. We need additional information (like fault…
