Abstract:

Broadband data are accumulating in the Berkeley system and provide excellent data on teleseism and local earthquakes and explosions. The August 1975 Oroville earthquake provided a successful test of the broadband system under relatively strong 1-2 mm ground displacement ground displacement. Attenuation studies continue with extension of variational formulation to dissipative surface wave propagation and observations of localregional earthquakes over a broad spectral band.
