The aftershocks continue following the Mw 5.7 mainshock earthquake swarm along the Mendocino fault. Yesterday I plotted my interpretation for the location of the fault that this swarm may have ruptured upon. Some epicenters have been relocated and appear to…
Mendocino fault earthquake 1/28/15 1:08 PM local time
We just had a good sized shaker, probably on the Mendocino fault system. Today’s earthquake occurred on 1/28/2015 at 1:08 local time. The mainshock, an earthquake of magnitude Mw = 5.7, has an epicenter approximately 20 km due west of…
Cascadia’s 315th Birthday
On this morning, 315 years ago, the Cascadia subduction zone fault ruptured as a margin wide earthquake. I here commemorate this birthday with some figures that are in two USGS open source professional papers. The Atwater et al. (2005) paper…
Vancouver Isle M 6.6 Earthquake
Interesting little swarm here, on the coast of northwestern Vancouver Island. The convergence of these plates results in the Cascadia subduction zone (CSZ), that extends from Cape Mendocino in the South to at least Haida Gwaii in the North (there…
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 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…
Aftershocks from the M 6.8 Gorda plate earthquake
Here are some maps i have put together that show the accumulated aftershocks from the M 6.8 Gorda plate earthquake on Sunday night. There was one M 3.3 earthquake less than 30 minutes before the main shock. I draw the…
aftershocks from the M 6.8 Gorda plate earthquake from 2014/03/10
Here are some updated maps for this morning. There have been quite a few aftershocks. There are reports of landslides along the bluffs between Redway and Garberville. Here is a map that just shows these 22 earthquakes: Here is a…
