Deadly Guatemala earthquake landslides caused by specific geological factors.
The Guatemala earthquake in 1976 caused over 10,000 landslides in a 16,000 km2 area, leading to many deaths and property damage. Most landslides were in the highlands west of Guatemala City, with rock falls and debris slides being the most common types. Factors like seismic intensity, rock type, slope steepness, and fractures influenced where landslides occurred. Large landslides created hazards like blocked lakes and floods. The location of landslides was mainly determined by the type of rock and the landscape's features.
