WebApr 10, 2024 · “Rockslides are common in areas where geologic processes have caused the rock to be naturally weak or prone to weathering and fracturing,” Frasher wrote. “Especially in hilly or mountainous areas, and where rock masses are undercut by bodies of water, rivers, shorelines or roadways.” Rockslides tend to occur in rainy weather, Frasher wrote. Webrockslide: [noun] a usually rapid downward movement of rock fragments that slide over an inclined surface. Mass-wasting occurs whenever the gravitational force on the rock exceeds the ability of the slope to resist that force. Therefore, anything that erodes or impedes the mountain's ability to resist this force may be one of the causes of mass-wasting.
