Earthquakes

The seismometers located near the Mono-Inyo Chain are part of the greater Long Valley Caldera seismic network array.

Eruptions of explosion craters and lava domes, like Mono-Inyo, can include several hazard types. Minor tephra will accompany explosions and early vent opening. Lava flows will cover everything in their path, including roadways and infrastructure. Volcanic gases will be present in varying concentrations throughout eruption. The most dangerous possible hazards are pyroclastic flows and surges.
