Earthquake near the Santa Cruz Islands (western Pacific)!

Posted on: August 16, 2015 Last updated on: August 16, 2015 Written by: Jay Patton Comments: 2
Yesterday we had a large magnitude earthquake along a plate boundary that connects the South Solomon trench with the New Hebrides trench. This region had a swarm of earthquakes in May. Here is the USGS website for the M 6.6…

New Guinea Earthquake Update #2

Posted on: July 28, 2015 Last updated on: July 28, 2015 Written by: Jay Patton Comments: 0
There have been a few more data products produced for this earthquake (that has not had any aftershocks). IRIS has produced some educational material, called “teaching moments” (or, could be called, learning moments, heheh). However, their data are often poorly…

Errata for Phantom Earthquakes: USGS

Posted on: June 2, 2015 Last updated on: June 2, 2015 Written by: Jay Patton Comments: 7
There have been a couple of reported earthquakes that have since been removed from the database. This happens when seismic waves are incorrectly interpreted by the computers, typically from the results of larger magnitude earthquakes. These large magnitude earthquakes can…

Blanco Fracture Zone: 2000 – 2015 Seismicity Animation

Posted on: June 1, 2015 Last updated on: June 1, 2015 Written by: Jay Patton Comments: 9
I put together an animation that includes the seismicity from 1/1/2000 until 6/1/2015 for the region near the Blanco fracture zone, with earthquake magnitudes greater than or equal to M = 5.0. The map here shows all these epicenters, with…
