1 + 2 = 3 (1) Tonight I was reviewing some core station sheets for some notes regarding over-penetration of the sea floor. This core station sheet was filled out with pertinent information about the core deploymnent. These are basically…

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…

Our paper has recently been published online and open source. Please find this here. This paper is part of a Natural Hazards and Earth System Sciences special issue on submarine paleoseismology. Spatially Limited Mud Turbidites on the Cascadia Margin: Segmented…
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…
M 4.7 Earthquake along Lake Toba, Sumatera
There was a M=4.7 earthquake today in central Sumatra along the Sumatra fault system. Interesting that it is following the 6.1 further to the north just a few days ago. in the map below, the earthquakes associated with the M…
M 6.1 in northern Sumatra
nice strike slip earthquake here in northern sumatra. pretty big, hope not many people were hurt. but, much smaller than could be observed on this fault system. the sumatra fault system is a right lateral strike slip fault system that…
Another large earthquake, along strike with the M8.3
here is an update to this series of interesting earthquakes. http://earthjay.com/earthquakes/20130523_sea_okhotsk/sea_okhostk_20130524_1000.PNG this one is along strike and at a similar depth to the M8.3. also an extensional earthquake, but with a more intermediate dip. it will be interesting to see…
