EARTHQUAKE EPICENTER
WE ALL KNOW THAT THE PHILIPPINES IS SITUATED IN A PLACE WHERE PLATE TECTONICS ARE VERY EVIDENT.
THE RING OF FIRE - is the long chain of volcanoes and other technically active structures that surround the pacific ocean
POlitical map & geophysical HAZARD MAP
POLITICAL MAP - illustrates the provinces and charted cities boundaries with their capitals and national capital.
HAZARD MAPS - shows you the areas in our country that are affected by grown , or vulnerable to a particular hazard or natural disasters
familiarize the legend found in each map...
LINE - means the provincial boundary between two locations and the risk of an area to a certain hazard or particular natural disaster is categorized into four.
‘EARTHQUAKES - are natural geological phenomena caused by sudden and rapid movement of large volumes of rock.The violence and destruction caused by earthquakes are the result of the rupture and slippage along fractures of the earth's crust called faults.
‘SEISMOLOGY - is the study of earthquakes and seismic waves that move through and around the earth.
‘SEISMOLOGIST - a scientist who studies earthquake and seismic waves.
There are several different kinds of seismic waves and they aall move in different ways.
THE 2 MAIN TYPES OF WAVES
Surface Waves
- can travel through the earth's inner layers
- can only move along he surface of the planet like cripples in water
Surface Waves are of a lower frequency than body waves and are easily distinguished on a seismogram though they arrive after body waves. It is the surface that is almost entirely responsible for he damage and destruction associated with earthquakes.
Body Waves
types of body waves
P - Wave
PRIMARY WAVES consist of a compressional or shortening motion and a dilational or expanding motion that both lie along a line. .
S - Wave
SECONDARY WAVES move in a direction perpendicular to the direction energy is traveling in or perpendicular or the direction of wave propagation.
types of SURFACE waves
Love Waves
Love waves, which are shear waves trapped near the surface
Rayleigh Waves
Rayleigh waves, which have rock particle motions that are very similar to the motions of water particles in ocean waves.
TOP 10 PROVINCES THAT ARE RISK TO EARHQUAKES
- SURIGAO DEL SUR
- LA UNION
- BENGUET
- PANGASINAN
- PAMPANGA
- TARLAC
- IFUGAO
- DAVAO ORIENTAL
- NUEVA VIZCAYA
- NUEVA ECIJA
La Union and Pangasinan are prone to earthquakes especially the deep focused ones due to the Manila trench. Surigao Del Sur and Davao Oriental have earthquake hazards due to the Philippine trench and nearby active faults.
According to the Manila Observatory and the Department of Environment and Natural Resources, in the mapping of the Philippine vulnerability to environmental disasters seismicity or geographic and historical distribution of earthquake events is all over the country except in the Palawan Region which is the safest in the country due to its very low risk in a geological disaster like earthquakes.
