Virtual Seismologist

TheĀ  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.

For more information please visit the VS research page.

ShakeAlert V1.2 rolled out in April extending the “production prototype” to Washington and Oregon!
