Abstract
Recent earthquakes, ground uplift, and increased hydrothermal activity are only the most recent examples of intense tectonic and volcanic activity that has occurred at Long Valley caldera, CA, over the last 3 million years. A large number of geophysical experiments conducted by several hundred investigators over the past few years clearly indicates that a major body of magma exists within the central part of the caldera at drillable depths on the order of 5 km. Plans are underway to drill toward and eventually into this magma body. 2 figs., 1 tab.Keywords
