Abstract

Statistical analysis is a tool to calculate earthquake probabilities. In this work, the previous earthquake data from 1918 to 2016 with the magnitude level 6 and above have been analyzed. From the data analysis, weibull parameters, namely, shape parameter (β), scale parameter (τ) and rate parameter of exponential distribution (λ) have been determined. To calculate earthquake probabilities for the upcoming years, weibull distribution, log-normal distribution and exponential distributions have been studied. These three statistical distributions have been compared among them in five major faults in and around Bangladesh.
