IRIS Program for Array Seismic Studies of the Continental Lithosphere (PASSCAL)

Several of these use earthquakes as sources and several use explosive sources. Studies include a reflection/refraction profile of the northern Brooks Range, a study of discontinuities in structure beneath Mauna Loa, a transect from western Ontario to Wyoming, a high frequency study at Pinyon Flats, seven data sets on the Loma Prieta earthquake, an experiment in the Ouachita, three studies from the Basin and Range province, experiments in Hawaii (ALOHA) and Iceland, and many others.

The data from studies using synthetic sources is generally in IRIS SEGY (Society of Exploration Geophysicists Y) format. Earthquake data is in in tar files using AH traces and SEED (Standard for the Exchange of Earthquake Data). Availability of PASSCAL Data may be determined by visiting the Temporary Network Data Status for Experiments Beginning in Years 1998-2000, &iris.washington.edu/PASSCAL/1998-2000.html&.
