We examined ground motion envelopes of horizontal and vertical acceleration, velocity, and filtered displacement recorded within 200 km from Southern California earthquakes in the magnitude range 2 < M <= 7.3. We introduce a parameterization that decomposes the observed ground motion envelope into P-wave, S-wave, and ambient noise envelopes. The body wave envelopes are further parameterized by a rise time, a duration, a constant amplitude, and 2 coda decay parameters. Each observed ground… CONTINUE READING
