all right, another M 6.2 aftershock in Chile

Posted on: April 2, 2014 Last updated on: April 2, 2014 Written by: Jay Patton Comments: 5
While I was writing my post about the M 7.6 aftershock, we got a M 6.2 aftershock. A M 6.2, while still large, is much smaller than a M 7.6. Each step in earthquake magnitude (e.g. from M 5 to…

Fault Model 3-D Animation for La Habra EQ Swarm

Posted on: April 1, 2014 Last updated on: April 1, 2014 Written by: Jay Patton Comments: 9
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

Posted on: April 1, 2014 Last updated on: April 1, 2014 Written by: Jay Patton Comments: 1
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…
