About these files

Each file is plain text in the SCEC Broadband Platform layout. Lines starting with # are a header describing the earthquake, the site, where the motion came from, how it was processed, its peak values, and which part the animation shows. Then come four columns: time (s), north–south, east–west, and up–down. North–south comes before east–west.

Units: acceleration in cm/s², velocity in cm/s, displacement in cm. The zip also contains the plots and a README.

To read a file in Python: t, ns, ew, ud = numpy.loadtxt("file.acc.bbp", comments="#", unpack=True). A spreadsheet can open it as whitespace-delimited text.

These records explain what the animations show. A single simulation, one station’s record, or a synthetic scaled to one value is not an engineering estimate of ground motion at a site.

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 — Est. Vs30

GMPEs use the Est. Vs30 values shown in the table above. ShakeMap values are independent of Vs30.

GMPE Residual — Observed − Predicted MMI

Signed residual at each seismic station. Positive values mean the GMPE underestimated shaking; negative values mean it overestimated. The dashed line at zero indicates perfect agreement.

GMPE Predicted vs. Observed MMI at Seismic Stations

Each point is one seismic station. Points on the dashed 1:1 line indicate perfect agreement; above the line = GMPE underestimated shaking; below = overestimated.

GMPE Performance — Station Observations

Statistics computed by comparing each GMPE's predicted MMI against ShakeMap observed MMI at seismic stations. Bias = mean(observed − predicted). Lower RMSE indicates better overall agreement with instrumental measurements.

GMPE	Bias	Sigma	RMSE	N Stations
ASK14	+0.83	0.88	1.21	108
BSSA14	+1.34	0.89	1.61	108
CY14	+1.18	0.86	1.46	108
CB14	+1.20	0.91	1.51	108

Bias > 0: GMPE underestimated shaking at stations. Bias < 0: GMPE overestimated shaking.

Peak Ground Motion — Seismic Station Observations

Recorded PGA and PGV at seismic stations, sorted by highest PGA. Top 25 stations shown. MMI (PGA) and MMI (PGV) are independent conversions via Worden et al. (2012) GMICE.
