profiling hazards
can be assessed by the measurements obtained from scientific instruments
magnitude or strength of the event
tells the area’s proneness to the hazard
frequency
This is usually, but not always, associated with the area’s geographical location on earth or its topographical condition
frequency
Sometimes, scaling can vary depending on the reference tables used per country
Magnitude or strength of the event
the impact of hazards varies in duration. the assessment of the duration is either short or long
Duration of impact
Whether the exposed element receives the likely disaster directly or indirectly
Casualty of events
Other elements that are not visible present in the site of event also suffer some degree of consequences because all communities interact within and outside their territory
Casualty of events
is a location where a natural hazard is likely to happen if preventive measures are not implemented
Hazard-prone areas
an area surrounding the basin of the pacific ocean where many volcanoes have formed. Seismic activities such as earthquakes and volcanic eruption frequently occur in the region
pacific ring of fire
is a crack or break in earth’s crust along which rocks have moved
fault
fault is a crack or break in earth’s crust along which rocks have moved. a rapid or sudden movement of rocks releases a large amount of seismic waves, which cause the ground to move or shake
philippine fault zone
