GEOLOGY

Detailed explanation-1: -Natural Hazards can also be divided into rapid onset hazards, such as Volcanic Eruptions, Earthquakes, Flash floods, Landslides, Severe Thunderstorms, Lightening, and wildfires, which develop with little warning and strike rapidly.

Detailed explanation-2: -Rapid Onset Disasters. Disasters and consequent emergencies may occur suddenly or develop over a period of time. Rapid-onset emergencies are usually the result of sudden natural events such as wind storms, floods, wild fires, landslides, avalanches, earthquakes and volcanic eruptions.

Detailed explanation-3: -A slow-onset disaster is defined as one that emerges gradually over time. Slow-onset disasters could be associated with, e.g., drought, desertification, sea-level rise, epidemic disease. A sudden-onset disaster is one triggered by a hazardous event that emerges quickly or unexpectedly.

Detailed explanation-4: -Volcanic eruptions, earthquakes, flash floods, and landslides are examples of rapid onset hazards.

Detailed explanation-5: -Natural hazards can be classified into several broad categories: geological hazards, hydrological hazards, meteorological hazards, and biological hazards.
