Volcano Hazards in the Long Valley - Mono Lake Area, California

Volcanic unrest through the 1980's to 1990's in the southern part of the Long Valley caldera reminds us that the volcanic system is young. Volcanic activity and related hazards are likely in the future. USGS scientists closely monitor the area and research past activity to better understand what might happen in the future.
