Cari koleksi dengan cepat sesuai kebutuhan Anda.We observe seasonal seismic wave speed changes (dv/v) in the San Jacinto fault area and investigate several likely source mechanisms. Velocity variations are obtained from analysis of 6 yr data of vertical component seismic noise recorded by 10 surface and six borehole stations.We study the interrelation between dv/v records, frequency-dependent seismic noise properties, and nearby environmenta…
