The GPS receivers near the Mono-Inyo Chain are part of the 46 instruments that make up the Long Valley Caldera monitoring network.

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.

Scientists designed a simple experiment to demonstrate how the cracks and faults along the Inyo chain might have formed above a shallow intrusion of magma.
