CyberShake 21.12 is a computational study to use a new ERF with CyberShake, generated from an RSQSim catalog. We plan to calculate results for 336 sites in Southern California using the RSQSim ERF, a minimum Vs of 500 m/s, and a frequency of 1 Hz. We will use the CVM-S4.26.M01 model, and the GPU implementation of AWP-ODC-SGT enhanced from the BBP verification testing. We will begin by generating all sets of SGTs, on Summit, then post-process them on a combination of Summit and Frontera.

Status

This study is in the pre-production phase. Production is scheduled to begin in mid-December, 2021.

Data Products

Science Goals

The science goals for this study are:

  • Calculate a regional CyberShake model using an alternative, RSQSim-derived ERF.
  • Compare results from an RSQSim ERF to results using a UCERF2 ERF (Study 15.4).

Technical Goals

The technical goals for this study are:

  • Perform a study using OLCF Summit as a key compute resource.
  • Evaluate the performance of the new workflow submission host, shock-carc.
  • Use Globus Online for staging of output data products.

ERF

The ERF was generated from an RSQSim catalog, with the following parameters:

  • 715kyr catalog (the first 65k years of events were dropped, so that every fault's first event is excluded)
  • 220,927 earthquakes with M6.5+
  • All events have equal probability, 1/715k

Additional details are available on the catalog's metadata page.
