A method for epicenter locating by using T waves
摘要
Abstract
Two OBS arrays were deployed in the southern Okinawa Trough. Some of the OBS records revealed many earthquakes with intensive T waves but ambiguous body waves. A new method using T waves for epicenter locating was developed that was found to be as precise as the body wave method for locating epicenters when T waves are clearly recorded.
