Abstract

This study contains the most recent seismic hazard map of Southeast Asia. This area is located to the south of the Eurasian plate. The Ring of Fire that surrounds the region makes it one of the most active in terms of earthquakes and volcanoes. Malaysia, Indonesia, Thailand, Singapore, the Philippines, Myanmar, Vietnam, Laos, Cambodia, and Brunei are among the countries being studied. The goals of this project are to provide Peak Ground Acceleration (PGA) values for all regions in ASEAN countries, and then to create seismic zoning maps for these countries so that zones with non-seismic regions can be identified and zones with no special steel reinforcement-detailing requirements can be specified. The final step is to create design response spectra. Based on each nation's most recent body of literature, the PGA hazard map is created. There are two maps that need to be created, one for 10% and one for 2% probability of exceeding. The PGA contours of all the compiled maps were then reconstructed, and the baseline colours were compared to an Indonesia seismic hazard map. The maximum PGA value for Southeast Asia is as high as 0.8g at 10% and 2.0g at 2% probability of exceedance, respectively, whereas the minimum PGA value is typically equal to 0.0g at both 10% and 2% probability of exceedance. The design response spectrum distribution of the stable with moderate earthquake region from 0 to 4 s (including West Malaysia, Sabah and Sarawak of East Malaysia) and the distribution of spectra for active earthquake regions including Indonesian cities (including Acheh, Padang and Palu) are plotted. Then, the design response spectra for the selected cities in regions of moderate seismicity and active earthquakes are integrated.
