Abstract - The general purpose of the present paper is to summarize the state-of-the-art of historical earthquake knowledge and research in the Sabah region, giving an account of the main references, the historical developments and the present situation of earthquake catalog. The most representative historical works for compiling earthquake data (catalog) up to 1900 are referred together with those of more recent investigations for the period 1900 - 1984. The seismicity around Sabah has a complex seismotectonic setting. Usually, the region has an earthquake pattern that clearly indicates the non-uniformity in the seismic activity. The seismicity rate around East Malaysia come from outside sources either from Kalimantan, Sulawesi and Southern Philippines and local sources that appear to be associated with some local faults and weak zones producing low-to-moderate magnitude of earthquakes. Updated databases on historical seismicity are presented, mentioning the most important achievements in relation to quality of information. The PGA values for 10% probability of exceedance is 170 cm/s2 and 2% probability of exceedance is 300 cm/s2.
