Geological Hazards

Landslide

a result of the downward

and outward movements of large

volumes of soil and/or rock down

slopes under the influence of the force

of gravity.

Retrogressive Landslide

happen when the top layer of soil begins to slide down

Piecemeal Landslide

A type of landslide that can occur when multiple landslide events happen in the same place

Reactivated Landslide

happen

when the area of a previous

landslide incident is disturbed,

which results into the reactivation

of another landslide.

Sinkholes

where the rock below the land surface is carbonate rock, salt beds, or rocks that can actually be dissolved by groundwater through them

Human-induced Sinkhole

Activities caused by humans

Groundwater Pumping

Lowering groundwater levels can lead to underground

structural failure and sinkholes.

Construction

construction can cause sinkhole

Abandoned Septic Tank

Even

after communities switch to sewer systems, old septic tanks can remain and cause sinkholes.

Hydrometeorological Hazard

- a phenomenon of atmospheric, hydrological or oceanographic nature that may cause loss of life, injury, or other health impacts, property damage, loss of livelihoods and services, social

Typhoon

that occurs

especially in the region of the Philippines or the China Sea.

Thunderstorm

a weather condition generally characterizes by heavy rain, thunder, lightning and even the possibility of tornado.

Flashflood

Storm Surge

an escalating seawater to the coast above normal sea level.

El Niño

a flow of unusually warm water along the western coast of South America that causes many changes in weather in other.

La Niña

a
climate pattern that

describes the cooling of surface ocean waters along the tropical west coast of South America. It is considered as the counterpart of El Niño, which is characterized by unusually warm ocean temperatures in the equatorial region of the Pacific Ocean.
