Application of Rapid Earthquake Damage Assessment System (REDAS) for Seismic Risk Estimation
Azotea. Marc Sinan B,Dungca. Gabriel Bautista,Herrera. Odyssey 한국방재학회 2017 Journal of Disaster Management Vol.2 No.3
An earthquake in the Philippines is already an everyday life for the people. Marikina City in Manila is a home to four hundred thousand residents located near a valley fault with a system capable of creating large-scale earthquakes of magnitude 7 or more. Thus, the objective of this study is to assess the possible risk that can be brought about by “The Big One”, a 7.2 earthquake using previous events and surveyed data with the help of the Marikina Research & Planning Division. The importance of this research is that it would greatly help in reducing the effects of earthquake disasters as this presents data of areas which would deal great damage on its geographic location and buildings which are prone to devastation. Moreover, the study aids in the planning and mitigating of the possible consequences of disaster events which would eventually aid in the development of plans for recovery and reconstruction following a disaster. The scope of this research however is only limited to all areas inside Marikina City and would only focus on the seismic assessment for the said area. All the necessary data input required in the study both primary and secondary were obtained from surveys and site inspections for the three barangays in Marikina. All of which are in coordination with the Marikina City Disaster Risk Reduction and Management office and the Philippine Institute of Volcanology and Seismology. The results showed that using that Marikina City is indeed susceptible to ground shaking because of its geographic location and that from the physical damages in terms of floor area, damage with collapse is clearly evident and in terms of buildings damage with no collapse is the most defined. Additionally, for the number of casualties or fatalities, due to the fact the buildings are strong enough to withstand the earthquake hazard, therefore, fewer fatalities are portrayed, and rather slight damages were shown. As for the economic losses an estimated amount of 636,000 US dollars is expected from the aftermath of the earthquake. Therefore, from the outcomes shown, it can be stated that indeed Marikina City is of high seismic risk due to the proximity of it to the fault line and its development within the area. Also, even if casualties are of fewer numbers, complacency is still not an option for the government. Constant monitoring and evaluation is further need to correctly apply and abate the vulnerability of the area when the Big One occurs.
