Landslide is a major geomorphological process affecting landscape evolution in mountainous area;it may be not only triggered by rainfall or earthquake but also by human factors.Landslide source mechanisms have been studied in detail for decades using long-period seismic signals(Kanamori&Given1982;Eissler&Kanamori1987;Dahlen1993;Brodsky et al.2003).Long-period seismic signals may not be suitable for realtime landslide monitoring and early warning purposes due to the sparse stations distribution and insufficient accuracy of real-time source location.Previously,so many researchers have been prove that the landslides could be recorded by seismic stations apart from the source.The landslide at generated long-period seismic signals that were at least recorded by the IRIS Data Management System in China and Japan.Therefore,we use broadband seismic recordings to detect and analyze the seismic signals trigged by landslides.We have carefully read the arrivals at each station.
