Seismograms of noise recorded simultaneously at the surface and at two subsurface stations (335m and 945m below surface level) show that high frequency (1-100 Hz) background noise is reduced at the subsurface stations. Seismometers at all three stati

The recent Oaxaca, Mexico, earthquake November 29, 1978 (MW = 7.6, Ms = 7.8, seismic moment, M0 = 3.2 × 1027 dyne cm), is of special interest because of its location within a predetermined seismic gap. The event excited long-period (100–200 s) mul

A key element in successful seismic verification of a nuclear test ban treaty is the capability of a sparse network of seismic stations to accurately locate regional events. We have investigated the regional location accuracy of the Regional Seismic

A high-frequency seismic station has been operating since March, 1987, near Nelson, NV. Records of earthquakes at regional distances from the station show substantially more energy at frequencies above 10 Hz than records of nuclear tests of comparabl

Several large shallow earthquakes (Ms > 7.0) have occurred along the Middle American Trench since the installation of the WWSSN network. Included are the 1965, 1968, and 1978 Oaxaca events, the 1970 Chiapas event, the 1973 Colima event, and the 1979

Global average estimates of the group velocity and attenuation of long-period (120–300 s) Rayleigh waves were made using seismograms from the epicenter's antipode (Δ≃180°). Focusing at the antipode produced amplified arrivals with favorable sig
