CyberShake Study 21.12
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.

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.
