| Summary: | The objective of this research is to develop the framework for sustainable land-use
planning on the basis of seismic microzonation to reduce the devastating effects of future
earthquakes by utilizing the software geographical information system (ArcGIS). Miri
district of Sarawak in Malaysia has been chosen as the study area because of having the
highest peak ground acceleration which is 0.09g in terms of the 10% probability of
exceedance in 50 years. In addition, the frequency of an earthquake with a magnitude up
to 5.3 is approximately every 5-7 years. Therefore, it is vital to introduce land use
planning in order to diminish the adverse effects of earthquakes in the future. For this
purpose, Google Earth Pro was used for the collection of satellite image data for land use
planning purposes. From the results, it was found that the seismic hazard in the Miri
district varies from low to high corresponding to 2475 years of return period with low to
moderate as predominant over the Miri district. Only a few areas are under high hazard.
Also, the land use planning map was compared with the current land use map acquired
from satellite imagery and it was found that all built-up is in the low hazard area. It is
envisaged that the findings from this research will contribute immensely to the literature
that will serve as background information and a guide for analysts, disaster management,
engineering designers and seismologists in Malaysia and the world as a whole. |
