CONCEPTS AND TYPES OF DISASTER
CONCEPTS AND TYPES OF DISASTER
A. CLASSIFICATION OF NATURAL DISASTER
One. GEOPHYSICAL - occurs as a force of nature (also known as natural processes) : stems from the Earth's crust.
Moving of tectonic plates.
GEO - greek word "earth" PHYSICAL - matter and energy ex. earthquakes, volcanic eruptions, landslide
Involvement of major tectonic plate movement
Activity occur beneath the Earth crust
Two. METEOROLOGICAL - atmospheric caused by weather conditions violence but short-lived events.
ONSET: Sudden
Three. CLIMATOLOGICAL - is caused by extreme climate patterns and can cause persistent negative impact on multiple sectors on people's lives.
also known as extreme climate patterns (shifting from extreme warm to extreme coldness).
ONSET: Gradual ex. forest fire, drought, El Niño Caused by unusual warming of the surface water in the Pacific.
ON set is gradual.
Affected: Farmers
La Niña - caused by extreme coolness.
Four. HYDROLOGICAL - stem from atmospheric, oceanographic or hydrological processes leading to loss of lives, property damage and disruption.
ex. flashfloods (due to obstructive drainages), tsunamis
Five. BIOLOGICAL - are events that involve the rapid incidence and prevalence of vector-driven diseases, toxins or pathogens.
Virus, Bacteria can be present that can be trigger by nature ex. Epidemic, pandemic, COVID-nineteen Virus from nature
