The result is an accurate set of velocity and displacement traces that can be used in a wide variety of source-mechanism and ground-motion studies. These revised processing procedures are applied...

...) . The name was derived from a Greek word that means wool because at the type locality the erionite occurs as white, wool-like fibers.

... were filtered using an Ormsby band-pass filter with corner frequencies of 2, 8, 16, and 32 Hz. Crooked road geometry, ∼2 km of elevation variation, and narrow near-surface basins produced irregularities in the Pg arrival times of up to 250 ms delay between stations <200 m apart. To correct...

The application of the frequency filter was preceded by a predictive deconvolution (120-ms operator length, 10-ms prediction distance...
