This page documents the BBP Group activities to simulate events from the Ridgecrest Sequence.

Events Considered

Observational Data

Station Selection

  • For the validation, Christine selected all the stations within a closest distance (Rrup) of 125 km of all three events. This yielded ~ 50 stations, most of which have recordings for all three events.
