Long Valley volcanic update


  • Anonymous


A relatively low level of earthquake activity and reduced rates of ground deformation during the past year have led U.S. Geological Survey (USGS) scientists to conclude that the likelihood of imminent volcanic activity at Long Valley, Calif., is reduced from that of mid-1982 through 1983.

In a letter dated July 11, 1984, USGS Director Dallas Peck advised the California Office of Emergency Services that, based on the assessment of the current situation, a volcanic eruption does not pose an immediate threat to public safety in the Long Valley region.
