Potential hazards from pyroclastic flows and surges
for small to moderate-sized eruptions from
along the Mono-Inyo Craters volcanic chain
or in the south moat of Long Valley Caldera, California

Map of potential pyroclastic-flow hazards in the Long Valley area, California
Map from C.D. Miller, modified by J. Johnson.

Map shows hazard zone for pyroclastic flows and surges around existing explosive vents along the Mono-Inyo Craters volcanic chain and from potential vents located in the south moat area of Long Valley Caldera.

This hazard zone is based on explosive eruptions from vents located along the chain in the past 10,000 years that are known to have that ejected <1 km3 of magma and generated pryoclastic flows or surges. Future pryoclastic flows and surges from a single eruption from along the Mono-Inyo chain or in the south moat would affect only a part of the total hazard zones shown on the map.
