Here is a short animation I made to visualize the fault geometry possibly associated with the earthquake swarm in La Habra this past week. I placed 2-D maps of these fault models here. Here is the animation. (~41 MB avi)
Fault Model in 3-D
Here are a couple maps that I put together to help me visualize a potential fault that may have ruptured in La Habra on 2014/03/29. This is a very quick, coarse, and precursory look. Others have better tools and will…
La Habra M 5.1 earthquake update
Well well. The faults in southern CA are large in number. Following Danielle’s lead, I looked into the tectonics of the region. The Shaw et al. (2002) paper has a really good summary of the tectonics of this region of…
M 5.1 earthquake in La Habra
All Right! A good sized shaker (nice and small) just happened near La Habra in southern CA. Here is the USGS web site for this earthquake. Here is some general information about earthquakes in southern CA. This is a really…
Interseismic Fault Coupling: the 2014 March Northern Chile Swarm
Given the paucity of great earthquakes in the region of the recent earthquake swarm along the subduction zone offshore or northern Chile, we are curious to know if there will be a large magnitude earthquake there. The seismologic record of…
Still kicking off some aftershocks in northern Chile
Here is the latest view of the seismicity associated with this earthquake swarm offshore northern Chile. I first mentioned this since I thought it was an interesting region to get some earthquakes. Read more about that on that first page.…
Indian Ocean M 5.4 2014/03/27
Good Morning! A very coolio M 5.4 earthquake in the northern Indian Ocean between the Ninetyeast Ridge and Sri Lanka. Here is the USGS webpage for this earthquake. This is interesting because it is northwest of a swarm of earthquakes…
Andaman Sea Swarm M 6.5
Here is a good sized earthquake swarm in the Andaman Sea. I am a little late posting this, I was otherwise detained. Here is the USGS webpage for the Mw 6.5 earthquake. The Andaman Sea is a region of back-arc…
Gorda plate earthquake animations
I have put together a couple animations of the earthquake epicenters preceding, during, and following the recent earthquake swarm in the Gorda plate. Here is the first page I put together for this M 6.8 earthquake. Here are some maps…
M 6.7 earthquake swarm in northern Chile! 2014/03/06
There was a really cool earthquake swarm in northern Chile. This swarm of earthquakes are at depths that places them near the subduction zone fault interface. This earthquake swarm is interesting for several reasons, the first of which is that…
