Geological Hazards and Risk Reduction

A set of flashcards focusing on vocabulary related to geological hazards, landslides, sinkholes, and preparedness measures.

Geological Hazard

Events that occur irregularly in time and space and cause negative impacts on man and the environment.

Landslide

The movement of rock, earth, or debris down a sloped section of land.

Sinkhole

A hole in the ground that forms when water dissolves surface rock, often limestone.

Mass Wasting

Any downward movement of material that wears away the Earth's surface.

Geology

The study of the physical formations of the Earth.

Morphology

The structure and form of the land.

Mitigation Strategies

Plans developed to coexist with natural hazards and reduce their negative effects.

Warning Signs of Landslide

Indicators such as new cracks in the ground or rapid increase in creek water levels that may suggest landslide risk.

Types of Landslide Movement

Includes falls, topples, translational slides, and flows.

Landslide Preparedness

Preparedness measures include developing an emergency plan and being aware of evacuation routes.

Evacuation Plan

A plan developed for safe relocation during emergencies such as landslides.

Debris Flow

A rapid flow of debris that can occur during landslides, often carrying water, soil, and other materials.

Human Activity

Actions, such as construction or agriculture, that can increase the risk of landslides.
