Concept of Disaster and Disaster Risk - Mrs. Roma Jane D. Castillo, LPT

A series of waves caused by earthquakes or undersea volcanic eruptions.

Rapidly rotating storm systems characterized by a low-pressure center, strong winds, and heavy rain.

A downslope movement of soil and rock under the influence of gravity.

A specific type of snowstorm consisting of large amounts of snow lasting more than three hours.

A violently rotating column of air in contact with both the Earth's surface and a cumulonimbus cloud.

When lava and gas are released from a volcano.

A temporary overflow of water onto land that is normally dry.

An uncontrolled fire in an area of combustible vegetation.

A depression or hole in the ground caused by some form of collapse of the surface layer.

Industrial accidents, shootings, acts of terrorism, and incidents of mass violence.

A disaster is a sudden, calamitous event that seriously disrupts the functioning of a community or society and causes human, material, and economic or environmental losses.

Disaster risk is defined as the potential loss of life, injury, or destroyed or damaged assets which could occur to a system, society or a community in a specific period of time, determined probabilistically as a function of hazard, exposure, and capacity.

The learning objectives include: explaining the meaning of disaster, differentiating the risk factors underlying disasters, describing the effects of disasters, explaining how and when an event becomes a disaster, identifying areas exposed to hazards, and analyzing disasters from different perspectives.

Yes, disasters can have human origins.

Hazard, exposure, and capacity are the factors contributing to disaster risk.

Disasters exceed the ability of communities or societies to cope because of the human, material, and economic or environmental losses they cause.
