Virtual Seismologist

The  Virtual Seismologist (VS method) was retired from the ShakeAlert production prototype system in November 2016.

The Virtual Seismologist (VS method) uses envelopes of acceleration, velocity, and displacement as the basic data input to a Bayesian framework that also incorporates other types of information (e.g., topology of the seismic network, recent seismic activity). The system is named the Virtual Seismologist (VS method) since the goal is to mimic the type of robust analysis that a human would perform, but in a greatly reduced amount of time.
