| Abstract;We demonstrated the Source-Scanning Algorithm (SSA) to image the source region of the deep low-frequency (DLF) events. It is difficult to locate DLF events precisely using conventional hypocenter determination method such as using P- and S-wave arrivals, because of emergent onsets of those phases. The SSA method just stacks observed seismograms to locate source region of the events, without using the arrival time information of particular phases such as P or S. Therefore, the SSA method is a powerful tool to locate the events with emergent onsets such as DLF events. We applied the method to the synthetic and real seismic data to demonstrate the potential of the method. (author abst.) |
