Hazards Summary for San Francisco Volcanic Field
Although there has been no eruption for nearly 1,000 years, it is likely that eruptions will occur again in the San Francisco Volcanic Field.

The most probable sites of future eruptions are in the eastern part of the field. Impacts from the eruption should be localized near the vent. These future eruptions may provide spectacular volcanic displays but should pose little hazard because of their small size and the relative remoteness of the area.
