Today we had a M 4.9 earthquake northwest of Bakersfield in the middle of the southern San Joaquin Valley. At first, it looked like there were no faults here because I was looking at the USGS fault and fold database.…
Earthquake Report: Antarctic plate!
We just had an interesting mid-plate earthquake (not along a plate boundary). Hat Tip to Jascha Polet, who pointed out this is in the region of the 1998 M 8.1 earthquake, one of the largest strike-slip and mid-plate earthquakes ever…
Earthquake Report: Macquarie – New Zealand
There was an earthquake along the plate boundary between the Australia plate to the west and the Pacific plate to the east, just south of New Zealand. Here is the USGS website for this M 6.2 earthquake. Yesterday on 2015/02/14…
Earthquake Report: New Zealand!
Early on Valentines, those in New Zealand got a valentine from mother Earth. Here is the USGS website for this M 5.8 earthquake, which was felt broadly across the region. This earthquake, and an M 4.1 aftershock, occurred in the…
Earthquake Report: Chile!
The aftershocks from the 2015.09.16 M 8.3 Chile earthquake continue. Today was an earthquake with magnitude M = 6.3. Here is the USGS website for today’s earthquake. I presented a comprehensive review of Chile’s historic seismicity, as well as the…
Earthquake Report: Taiwan Update #1
People have been busy documenting the damage from the M 6.4 earthquake in Taiwan. Here is my initial Earthquake Report for this earthquake. Here are a couple news sources on the damage. There appears to be a few large buildings…

Earthquake Animation: Gorda Plate 1900-2016 M >+ 4.5
Following the earthquake pair today, I put together an animation showing the seismicity for this region between 1900 and 2016.01.30. I searched the USGS NEIC database for earthquakes of magnitude greater than or equal to M = 4.5. Here is…
Cascadia subduction zone: M 9.0 tsunami simulation video
NOAA Center for Tsunami Research just released an animation that shows a numerical simulation of what a tsunami may appear like when the next Cascadia subduction zone earthquake occurs. I present a summary about the CSZ tectonics on a 316th…
