Santa Cruz Islands Earthquake: Update #1
The USGS has presented their moment tensor solution for this M = 6.8 earthquake and it indeed appears to be a strike-slip type of an earthquake, supporting our interpretation that this is a transform plate boundary. Here was my first … Continue reading

Nepal (Gorkha) Earthquake: USGS Slip Models

The USGS has processed an inversion of the seismic data for a slip model for the Mw 7.3 earthquake. I have rubbersheeted their fault plane solution, as well as the solution for the Mw 7.8 earthquake for comparison. Please find … Continue reading

Large Aftershock in Nepal: 3rd Update
After some debate online, I decided to put this quick map together. Clicking on the epicenters in google earth or on the USGS earthquakes page, one can easily determine that there were aftershocks from the 2015.04.25 Mw 7.8 earthquake in … Continue reading
Large Aftershock in Nepal: 1st Update
The first moment tensor has been calculated and I have plotted this Mww MT on the map. There has also been a small M 5.6 aftershock to this M 7.3 aftershock. Here is the map, that also includes moment tensors … Continue reading

Earthquake offshore of Bougainville!
Two days after the Mw 7.5 subduction zone earthquake along the New Britain trench, we get a swarm of seismicity further south offshore of Bougainville! (near the Solomon Islands) The largest earthquake has a magnitude M = 7.1. Here is … Continue reading

New Britain Strikes Again!
In the past week, there has been a series of earthquakes in the New Britain trench. The largest quakes are M = 6.7 & 6.8. Now we might call those foreshocks to today’s M = 7.5 earthquake de Cinco de … Continue reading
