Abstract: Geographical and tectonic settings of Bangladesh make it susceptible to seismic hazard. Besides, historical evidence says that numerous earthquakes with very large magnitude occur in this region. Currently, the Indian plate is gradually moving in the northeast and subduce beneath the Eurasian Plate. So, geologist suspects that a terrible earthquake with greater than eight (>8) magnitude is inevitable in this highly populated region. Therefore, assessing the integrated vulnerability of earthquake in this region is a prime concern for most of the geologists. In this paper, we performed a rigorous assessment of the earthquake’s vulnerabilities by analysing the historical earthquakes from the last 118 years (1901-2018) that occurred in Bangladesh and the surrounding regions (20.65° N to 28.00° N latitude and 87.00° E to 93.75° E longitude). Moreover, we also perform probability-based distribution analysis to show the intrinsic relationship among various parameters, especially earthquake magnitude and depth. Here, the necessary data are collected from the USGS (United States Geological Survey).
