another earthquake in the east Java / Timor region of Indonesia

Posted on: February 28, 2015 Last updated on: February 28, 2015 Written by: Jay Patton Comments: 5
We had another earthquake in this region today. This is an interesting area of the world since this is a place where there is a transition between subduction to the west and collision to the east. The Island of Timor…

Indonesia Strikes Again

Posted on: February 27, 2015 Last updated on: February 27, 2015 Written by: Jay Patton Comments: 2
A deep earthquake has occurred probably within the downgoing Indo-Australia plate. The moment tensor shows oblique extension (part strike-slip, part normal). The depth aligns with the depth of the plate given the Hayes et al. (2012) slab models (which ends…

another northeast Japan earthquake in the Tohoku-Oki earthquake region

Posted on: February 25, 2015 Last updated on: February 25, 2015 Written by: Jay Patton Comments: 2
We have had another small aftershock. Here is the USGS web page for this earthquake. This time it is in a different region than the swarm of the past couple of weeks. There are several report updates, listed here: 2015.02.16…

Gorda plate earthquake 2015.02.24

Posted on: February 24, 2015 Last updated on: February 24, 2015 Written by: Jay Patton Comments: 1
Where else would we get a focal mechanism or moment tensor for an earthquake of such a small magnitude! We are so lucky. This is the USGS web page for the earthquake. We get Gorda plate earthquakes frequently and most…

Tohoku-Oki aftershocks are in a region of low slip during main events in 2011

Posted on: February 21, 2015 Last updated on: February 21, 2015 Written by: Jay Patton Comments: 1
Here is what I was getting at in my last post. I have taken the Ammon et al. (2011) slip model and placed it into a real world reference frame (rubbersheeted it in ArcGIS). Then I exported it as a…

Tohoku-Oki Aftershocks Continue

Posted on: February 20, 2015 Last updated on: February 20, 2015 Written by: Jay Patton Comments: 3
The aftershocks continue offshore northeast Japan. The recent swarm appear to align along a northwesterly strike (trend). Here is the USGS web page for the earthquake from today. This is the USGS web page for the largest magnitude earthquakes in…

Japan earthquake may be aftershock to 2011 Tohoku-Oki earthquake

Posted on: February 16, 2015 Last updated on: February 16, 2015 Written by: Jay Patton Comments: 4
The USGS depth has been updated to 23.3 km. Now we may interpret this to be an interface earthquake. Here is my first post about this earthquake and here is a post about some aftershocks. There are several report updates,…

NE Japan aftershocks continue offshore the Sanriku coast

Posted on: February 16, 2015 Last updated on: February 16, 2015 Written by: Jay Patton Comments: 4
There continue to be aftershocks in the M 4-5 range. These are aftershocks and triggered earthquakes (if they are generally on different faults) from the Mw 6.7 earthquake. Here is my page on this mainshock and here is the USGS…

Sandwich Earthquakes in Scotia, mmmmm

Posted on: February 16, 2015 Last updated on: February 16, 2015 Written by: Jay Patton Comments: 2
We have had a swarm of earthquakes near the Sandwich Islands along the Scotia subduction zone, an oceanic subduction zone. Here is the USGS web page for this earthquake. Here is a map showing the regional tectonic setting with relative…

Earthquake offshore of the Sanriku Coast

Posted on: February 16, 2015 Last updated on: February 16, 2015 Written by: Jay Patton Comments: 6
We just had a good sized shallow compressional earthquake in the northern part of the 2011 Tohoku-Oki earthquake slip region. The USGS web page lists the magnitude at Mw 6.7. Here is a great summary of the tectonics of this…
