Today we had a M 8.2 subduction zone earthquake in northern Chile. I have placed some records of this tsunami here. Here is the National Tsunami Warning Center tusnami travel time map for this tsunami. Here is the National Tsunami…
M 8.2 earthquake in northern Chile
Alright. Lets hope not many people are harmed as a result of this earthquake and likely large tsunami. We all know what to do. Drop, duck, cover, and hold on. Run to high ground. Stay there. Check back here for…
Fault Model 3-D Animation for La Habra EQ Swarm
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…
Oso, WA landslide 2014/03/22 Historical Animations
Here are a few animations I made based on historical aerial imagery. There are four animations that run the years 1989, 2003, 2005, 2006, 2007, 2009, 2011, and 2013. I used the historic imagery available from google earth. There could…
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…
