rockslides
Tumbling boulder events
Rockslides are masses of rock that break loose and slide down a slope, often triggered by earthquakes, erosion, or heavy rain.
The term covers events ranging from minor debris flows to catastrophic collapses that bury roads or villages: The highway was closed due to rockslides.
Rockslide also appears as a single word.
