Summary: | Earthquakes are one of the most common and widely distributed natural risks to life and property. There is a need
to identify the possible risk by assessing the vulnerability of the research area. The topic on Earthquake Vulnerability
Assessment (EVAs) in Malaysia is very new and received little attention from geoscientists and engineers. Taking
the 5.0 Ranau Earthquake 2015 as research study, the research’s main objective was to identify the social
vulnerability and environment vulnerability on that area. The framework was formulated semi quantitively through
the development of database for risk elements (properties) based on the information from secondary data, literature
review and fieldwork. The vulnerability parameter includes social status (injury, fatalities, safety, loss of
accommodation and public awareness) and interference of environment (affected period, daily operation and
diversity). Each considered parameter in the vulnerability parameter is allocated with certain index value ranges
from 0 (0% damage/victims/period),0.25 (1-25% damage/victim/period), 0.50 (26-50%
damage/victims/periods), 0.75 (damage/victims/period), and 1.0 (75-100% damage/victim/periods). The value
obtained from field work are calculated by using formula and are classified into five classes of vulnerability namely
class 1 (<0.20): Very Low Vulnerability: Class 2 (0.21-0.40): Low Vulnerability; Class 3 (0.41-0.60); Medium
Vulnerability; Class 4 (0.61-0.80): High Vulnerability; and Class 5 (>0.81): Very High Vulnerability only. Results from
this study indicate that a further study is needed to the area of high to very high vulnerability only. This approach is
suitable as a guideline for preliminary dev |
