Abstract

Disaster incidents will disrupt the daily life and cause suffering to the victims of incident. The earthquake is one of the series unpredictable incident. This incident causes the concerns of academicians, engineers, planners, decision-makers and governments to prevent and manage the disaster. The disaster threat index is analyzed with using GIS software. The data that analyzed will divide into three levels which are a lower, moderate and extreme threat. The results of the analysis on the earthquake threats in Sabah revealed that 99.9% was in the area of earthquake threats with a total area is 7 382 144 ha while areas with no earthquake threats was 0.1% with an area is 17 206 ha. From the result also, known that the high seismic hazard index is Lahad Datu with an area of 463 540 ha while the lower earthquake threat index is Tambunan with an area of 588 ha. With this result, it will indirectly facilitate various parties to prepare and plan strategies to reduce the losses and damage from the earthquake disaster. Besides that, with the result also will facilitate the responsible agency to prepare an early safety plan to reduce the loss of life and property damage.

Highlights

A disaster is an occurrence disrupting the normal conditions of existence and causing a level of suffering that exceeds the capacity of adjustment to the affected community [1]
Malaysia has been categorized as belonging to the low seismicity group
Earthquakes have never caused any structural damage in Singapore and Kuala Lumpur, the consequences of even a moderate level of ground motion may be enormous because the high concentration of population and commercial activities taking place in structures that have not been designed for seismic loads [5]

Summary

Introduction

A disaster is an occurrence disrupting the normal conditions of existence and causing a level of suffering that exceeds the capacity of adjustment to the affected community [1]. Earthquakes have never caused any structural damage in Singapore and Kuala Lumpur, the consequences of even a moderate level of ground motion may be enormous because the high concentration of population and commercial activities taking place in structures that have not been designed for seismic loads [5]. The disaster threat index is compiled based on two main components which are first is possibility occurrence of a threat and frequency while a second component is the major impact that has been recorded in the disaster It can be said as an index compiled based on data and history records of events that have occurred in a particular area. Large or small the peak ground acceleration value is a factor that indicates the level of the earthquake threat [15]
