Abstract—Recently, the occurrence of the earthquake has been increasing around the world. The main purpose of the studies on the earthquake is to reduce the damage caused by an earthquake. To reduce the damage of earthquakes, we need to know the location of the epicenter exactly. Therefore, we propose a method to estimate the location of the epicenter based on the range difference of arrival (RDOA) algorithm. With a RDOA method, we can estimate the epicenter location from the distance data between the epicenter and the observatory. To determine a location of the epicenter from P-S time, we apply STA/LTA algorithm to measurement data. Also, we derive the objective function to minimize the estimation error by using recursive weighted least square (RWLS) algorithm. We prove the performance of the proposed algorithm through some simulation results.
