Stuart A. Rojstaczer, editor(s)
1994, Professional Paper 1551-E
Seismic events have long been known to cause changes in the level of oceans, streams, lakes, and the water table. The great San Francisco earthquake of 1906 induced significant hydrologic changes that were qualitatively similar to those changes observed for the Loma Prieta earthquake. What is different is that the...

Rewetting approximation for a simulator of flow in a surficial aquifer overlain by seasonally inundated wetlands
Michael L. Merritt
1994, Groundwater (32) 286-292
An approximation is presented to rectify situations occurring as part of the three-dimensional simulation of surficial aquifer flows in which surface grid cells become dry (zero saturated thickness) and then cannot readily receive flows that would again partially saturate them. The approximation permits the...

A. T. Linde, I. S. Sacks, M.J.S. Johnston, D.P. Hill, R.G. Bilham
1994, Nature (371) 408-410
Aftershocks of large earthquakes tend to occur close to the main rupture zone, and can be used to constrain its dimensions. But following the 1992 Landers earthquake (magnitude M(w) = 7.3) in southern California, many aftershocks were reported in areas remote from the mainshock. Intriguingly, this remote seismicity occurred in...
