Seismic events have long been known to cause changes in the level of oceans, streams, lakes, and the water table. The hydrologic data sets collected from the Loma Prieta earthquake of Oct. 17, 1989 have enough detail to enable hypotheses on the causes for such changes to be tested. These papers document changes in ocean level, stream morphology and flow, water table height, and groundwater flow rates in response to the earthquake. These papers deal strictly with postevent hydrologic changes, which appear to be the result of landslides, the static displacements induced by the earthquake, and changes in the permeability of the near surface.
