Rundle, J B

This paper gives a brief review of recent tectonic activity in the Long Valley, California, caldera, occurring since 1978. A series of major earthquakes, combined with ground uplift, crustal strain, gravity changes, hydrothermal system changes, and earthquake swarm activity all suggest the recent existence of a significant high level magmatic intrusion as the root cause of the activity. These data are outlined here, along with a program to investigate the nature and current evolution of this active caldera system. Current activities and future plans are also discussed. 23 references, 5 figures.
