Engineering Ground Motion Parameters

GMPE predictions provide an independent check on the ShakeMap interpolated intensities above. ShakeMap relies on seismic station recordings; in areas with sparse station coverage — or for large teleseismic events and earthquakes outside dense West Coast networks — ShakeMap MMI can be inaccurate. A significant difference between ShakeMap and GMPE estimates is a signal that the ShakeMap result should be treated as preliminary. Also includes site Vs30 values and raw ground motion parameters (PGA/PGV).

MMI vs Distance — Default Vs30 (760 m/s)

All methods using the 760 m/s rock-site reference. ShakeMap values are independent of Vs30.

MMI vs Distance — Site-Specific Vs30

GMPEs use the site-specific Vs30 values shown in the table above. ShakeMap values are unchanged.

Peak Ground Motion Values — USGS ShakeMap

PGA and PGV interpolated from the USGS ShakeMap grid for this event. Values reflect ShakeMap's ground motion model, not GMPE estimates.
