ABSTRACT OF RESEARCH

15/12/2012 14/12/2015 36 months

14/6/2016

(An abstract of between 100 and 200 words must be prepared in Bahasa Malaysia and in English.

This abstract will be included in the Report of the Research and Innovation Section at a later date as a means of presenting the project findings of the researcher/s to the University and the community at large)

Malaysia is located in seismlcally stable Sunda plate and has not experienced any disastrous earthquake occurrences. However, due to the location close to two of the most seismlcally active plate boundaries, i.e.

Indo-Australian and Eurasian plates, Malaysia has experienced numerous strong tremors caused by

earthquakes in those two seismically active zones recently. Regions of moderate to low seismicity such as Peninsular Malaysia are currently facing an intricate condition involving the prediction of probable seismic hazard. Paucity of strong motion records in these areas hampers earthquake ground motion estimation as well as the conduct of a comprehensive regression analysis of available data. For this reason, the research was carried out to determine an appropriate ground motion attenuation model for Peninsular Malaysia out of RU Grant Final Report I RCMO July 2015
