| Abstract: | The Ludian earthquake (MW 6.2) and Nepal earthquake (MW 7.8) are parameterized and then simulated using a new improved version of the stochastic point source method based on a proposed equivalent distance (REQL) measure. The improved method considers uniform slip distribution along the fault and is validated by comparing the simulated Fourier response spectrum. Simulated ShakeMaps of Ludian and Nepal earthquakes in terms of PGA also indicate that the results of the improved method are in good agreement with finite-fault method with high efficiency. |
