AK earthquake 2018

Nov 30th - All Day

Earthquake simulation of the Mw 7.0 Anchorage earthquake on November 30, 2018

A wave field simulation of the Friday, November 30, 2018 earthquake conveying basic information about the spatial and time scales of the seismic waves was modeled shortly after the earthquake by a team at the University of Alaska Fairbanks. The source is finite-fault model produced by USGS National Earthquake Information Center containing 14 subsources. The 3D structural model is a tomographic model from Eberhart-Phillips et al. (2016), plus embedded sedimentary basins of Cook Inlet, Susitna, and Peters Hill. Topography and bathymetry are modeled as well. The simulation is performed on a mesh of 4.7 million hexahedral elements. The simulation used the CIG code SPECFEM3D, run on 280 cores of the chinook cluster at University of Alaska Fairbanks. Technical notes of the simulations can be found on youtube.
