All right! That was exciting and a little bit scary. Most all earthquakes scare me because I recognize they might get bigger or trigger a bigger one. This earthquake is most likely on a northeast striking strike-slip fault in the…
M7.7 in Pakistan
A very large earthquake in Pakistan today! As a result of collision of the Arabia plate into the Eurasia plate, thrust faults formed in Pakistan. This collision zone is the same basic convergence region that extends from Java/Sumatra, up through…

M 7.0 on the Aleutian subduction zone
Here is another pretty big earthquake. Those on the islands of Adak and Atka probably got shook pretty strongly. The moment tensor shows a compressional earthquake and this is consistent with this setting on a subduction zone. If this EQ…
This is a map of modeled tsunami sea surface elevations.
People have been promoting ignorance and I am exhausted at explaining to each of them regarding this. The ongoing nuclear disaster at Fukushima Power Plant in northeast Japan is horrible. However, we as a society could want to be the…

Update on Sumatra Correlations
Here are two figures that go together. The first figure displays some cores in the region of the 2004 Sumatra Andaman subduction zone earthquake. The map shows their locations. The core figure shows the correlations I made using green lines…
M 6.8 on the South Island of New Zealand
here is a big earthquake! M = 6.8, now a 6.5 depth = 10km pretty shallow (may change). it ruptured part of the Marlborough fault zone (part of the Alpine fault system). the moment tensor fits the fault map, a…
