The Development of Health Capacity Index for a Semi-Quantitative Earthquake Hazards Risk Analysis with a Special Reference to the Lombok Earthquake Disaster 2018

Abstract

Earthquakes often caused severe fatalities to human beings, as the case of Aceh earthquake 2004, and Lombok earthquake 2018. For the case of Lombok shallow earthquakes 2018, the earthquakes of a magnitude 7.0 have destroyed almost 800 thousand homes, and caused the death of more than 500 people. The main problem of such a case is that the time occurrence of an earthquake cannot be predicted. However, the risk due to earthquake should theoretically be able to predict, when parameters can be calculated in the quantitative risk index of R = H x V/ C. Particularly in this paper, health capacity is introduced using a rating system in order to measure the resistance of people occupying disastrous area to overcome difficulties during hard time emergency shelter and disaster relief. Two study cases were conducted which show that the capacity index, particularly people health index, could differentiate between low and medium-high casualties among cities ruined by Lombok earthquake 2018. The development of a quantitative risk index, particularly health risk indexes, is therefore important in hazard mitigation due to earthquakes, that it provides a simple quick apparatus of disaster assessment.
