Earthquake Report: Bayside (northern California): Update #1
So, I put together another map with today’s earthquake in context with the historic seismicity and some other factors. Now the USGS magnitude is M = 4.7 and there is a moment tensor for this earthquake (that looks very similar…
Earthquake Report: East Pacific Rise and Middle America Trench
Yesterday we had an earthquake along the Clipperton fracture zone (CFZ), a transform plate boundary that offsets the northern East Pacific Rise (EPR). I was busy grading so did not get to this until today. Here are the four large…

Earthquake Report: Vanuatu!
We just had another M 6.9 earthquake about 40 km from another M 6.9 earthquake from a few days ago. Here is my earthquake report from that earlier earthquake. They are both about the same depth. While the depths probably…
Earthquake Report: Vanuatu!
We just had an earthquake along the New Hebrides Trench in the western Pacific. Here is the USGS webpage for this M 6.9 earthquake. Below is my interpretive earthquake report poster. I plot the epicenters for earthquakes from the past…
