GEOLOGY

Detailed explanation-1: -Earthquakes can trigger landslides and mudslides, especially in areas with water-soaked soils. Landslides may result in falling rocks and debris that collide with people, trees, animals, buildings and vehicles. They also can block roads and disrupt utility lines.

Detailed explanation-2: -Ground shaking from earthquakes can cause buildings and bridges to collapse; disrupt gas, electricity, and telephone services; and sometimes trigger landslides, avalanches, flash floods, fires, and tsunami.

Detailed explanation-3: -The ground shaking produced by the earthquake loosened rocks and ice on Mount Huascaran, one of South America’s highest mountains, 130 km away from the earthquake. This initiated a gigantic landslide, which increased in speed and size as it moved down the mountain, reaching a speed of over 200 km h-1.

Detailed explanation-4: -The health hazards associated with landslides and mudflows include: Rapidly moving water and debris that can lead to trauma; Broken electrical, water, gas, and sewage lines that can result in injury or illness; and.

Detailed explanation-5: -The impact of a landslide can be extensive, including loss of life, destruction of infrastructure, damage to land and loss of natural resources. Landslide material can also block rivers and increase the risk of floods.
