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…
large magnitude aftershock in northern Chile
There have been many aftershocks in the region of the 4/1/14 M 8.2 subduction zone earthquake offshore Iquique, Chile. There was a swarm of earthquakes up to M 6.7 in the weeks prior to the current main shock, here is…

Here are some plots from PMEL comparing model predictions with observations at several tide gages in the Pacific Basin. Crescent City, CA Los Angeles, CA Honolulu, HI Hilo, HI Kahului, HI
Tsunamis in the region of the M 8.2 northern Chile earthquake
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…
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.…
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…
M 5.2 Gorda plate earthquake 2014/03/13
This is a very cool earthquake! In the last few days, there was an earthquake swarm in the southeastern Gorda plate. This earthquake released accumulated strain along the faults in that region. A result of these earthquakes is that the…
