The following PDF file describes The Problem, version 35.

Description for TPV35 - Parkfield 2004 M6 Earthquake.

These are the data files for TPV35. They include the input data, station locations, and velocity model.

Data files for TPV35.


TPV35 is a model of the Parkfield 2004 M6 earthquake. This is our first validation benchmark. In addition to comparing the results of dynamic rupture codes to each other, we are also comparing the results to real-world seismic data.

TPV35 is based on a spontaneous rupture model from Ma, Custódio, Archuleta, and Liu (2008), Dynamic modeling of the 2004 Mw 6.0 Parkfield, California, earthquake, J. Geophys. Res., 113, B02301, doi:10.1029/2007JB005216.

Benchmark Dimension Rupture Type Material Properties Velocity Structure Minimum VS
TPV35 3D Right-lateral, vertical strike-slip. Linear elastic. 3D model. 1100 m/s.


The following data files are not necessary for performing the benchmark, but may be helpful. They contain the seismic recordings for the Parkfield 2004 M6 earthquake. There are two versions of the seismic recordings, one from NGA West 2, and one from Ma et al. 2008. The seismic recordings are also available on the code comparison website, where they have been uploaded by the modeler named "nature."

Seismic recordings from NGA West 2.

Seismic recordings from Ma et al. 2008.

Remarks: When viewing and comparing the seismic recordings on our website, we recommend setting the low-pass filter frequency to 1 Hertz. Parkfield 2004 seismic recordings do not have absolute timing information, and so only the shapes of the waveforms are significant. The timings of the waveforms are arbitrary. In these files, the timings have been shifted to correspond with modeling results.
