Debris Avalanche

The greatest hazard at Mount Adams, in common with many large stratovolcanoes, is from landslides, debris avalanches, and lahars

Slope failures and resulting debris avalanches are important processes at this volcano.

Eruptions from Mount Adams began about 520 ka, although scattered basaltic eruptions from the surrounding volcanic field began by about 940 ka.

Debris avalanches can be both large and small and pose relative sized threats.

The geological record of activity suggests that the most probable future eruptions would be small outbursts of tephra and lava flows from vents on the summit and upper flanks of the volcano rather than from the surrounding volcanic field.
