Factors Influencing Landslide Risk The likelihood and severity of landslides following an earthquake depend on a combination of geological and environmental factors. They can inundate coastal areas for kilometers inland, carrying with them everything from marine debris to entire buildings.
Rockfalls: A Major Secondary Earthquake Hazard
Unlike the seismic waves generated by the fault rupture, secondary hazards are phenomena triggered by the initial quake but occur through different physical mechanisms. Soil Liquefaction Soil liquefaction is a phenomenon that challenges the common perception of ground stability.
These landslides can range from small rockfalls to massive earth slides that obliterate infrastructure and bury entire villages. This displacement generates a series of powerful waves that can travel across entire ocean basins at jetliner speeds, gaining immense energy and height as they approach shallow coastal waters.
Rockfalls: Secondary Earthquake Hazards Triggered by Shaking
The intense ground motion reduces the friction and cohesion holding soil and rock together, causing entire hillsides to collapse. Soil type plays a crucial role; saturated clays and loose sands are more susceptible to failure than dense gravels or bedrock.
