Application of P-Wave Moment Magnitude (Mwp) and Rupture Time Duration (Tdur) to Analyze A Potential Tsunami Earthquake in Sumatra (original) (raw)

IOP Conference Series: Earth and Environmental Science, 2021

Abstract

Tsunami warning is one of many important reports to save lives and reduce the damage for local peoples. A moment magnitude of P-wave (Mwp) and the rupture time duration (Tdur) can be used as the quickly parameters to diseminate the tsunami warning. In this paper, we analyze the seismic waveform from global network to get Mwp and Tdur of South-West Coast of Sumatera earthquake. Mwp was calculated using automatic and manual phase picking of P phase. The results of this study show a well-analyzed relationship between P wave from automatic and manual picking, Mwp and time duration, respectively. The result also give an encouraging studies for the early warning system that will be set up in the future in the region.
