What are examples of geological hazards?

A geologic hazard is an extreme natural events in the crust of the earth that pose a threat to life and property, for example, earthquakes, volcanic eruptions, tsunamis (tidal waves) and landslides.

What is the most common geological hazard?

Geohazards
  • Earthquakes – Liquefaction (soils), Tsunamis.
  • Volcanic Eruptions – Lava Flows, Ash Fall, Lahars.
  • Landslides – Rock Falls or Slides, Debris Flows, Mud Flows.
  • Floods – Inundation, Erosion.
  • Snow Avalanches.
  • Sand Blasting (Windblown)

What are hazard prone areas?

The mortality risk due to hazards in a geographic area is the product of the probability of a hazard taking place in that area and the average vulnerability to hazards. An area is defined as hazard prone area if the mortality risk is higher than a certain threshold.

What is the cause of geological hazards?

Geological natural hazards such as earthquakes and volcanic eruptions are triggered by activities taking place in the earth’s interior. Gravitational natural hazards are defined as landslides, rockfall, debris flows or avalanches, since rock, mud or snow masses slide down the slope due to gravity.

What are the common causes of geological hazards?

Geologic hazards are generally caused by the movement of the plates in the Earth’s crust or the arising magma from underneath.

What is hazard and risk?

Hazard: something that could potentially cause harm. Risk: the degree of likelihood that harm will be caused.

Why is it important to identify the areas which are prone to?

It is important to identify areas that are prone to earthquakes in order to prepare for the possibility that they may occur. … If there is an area that rarely receives earthquakes of any significant size, there is no reason to construct every bridge, building, etc, to be earthquake resistant.

  3. Control the risks — Once you’ve identified the hazards and assessed the risks, look for ways to control them.

What may affect hazard risk?

Factors include: An increase in the number of people vulnerable to the natural hazard (e.g. population growth & increased population density close to hazard-prone areas) An increase in the frequency and magnitude of the natural hazard. A decrease in the number of people capable of coping with the natural hazard.
