Awareness for Natural Disasters
Disaster may happen any time in any place that is why we should be prepared for these scenarios. They are destructive and deadly if we aren’t ready for them. The school held an earthquake preparedness headed by Mr. Renato U. Solidum Jr., director of PHIVOLCS- an institute of the government assigned to regulate and monitor volcanic activities as well as earthquake predictions, effects and sources. The aim of this symposium was to inform the students, faculty members, administrators and those of general services of the necessary precautions to prevent further damage that may happen during earthquakes. Information, preparedness and understanding of these natural hazards are needed to reduce the loss of life and limb.
An earthquake is the sudden, rapid shaking or rolling of the Earth. In the Philippines, about 20 earthquakes are recorded per day and 200 per year. For the past 400 years, the Philippines had experienced about 90 destructive earthquakes one for every five years. Earthquakes happen because of volcanic activity and tectonic movements. It results to fault rupture, tsunami, ground shaking, liquefaction, landslide and fire. Faults- fractures where earthquake originates, there are different types of fault: strike slip, normal and thrust. Active faults move up & down while trenches move toward each other. The Valley Fault System has two segments, the East Valley Fault the West Valley Fault which covers Quezon, Marikina, Pasig, Makati, Pateros, Taguig and Muntinlupa. It has moved four times from the past 1600 years (an average of 400 years) per movement, generating earthquakes of magnitude 7.
Magnitude is the energy released at origin which differs from intensity- the perceived strength at the surface. Epicenter is the point at the earth surface directly above where the earthquake generated while focus- center of energy released during an earthquake are some of the terms encountered in the study of earthquakes.
