Background noise power spectral density (PSD) estimates for 54 PASS- CAL Colorado Plateau/Rio Grande Rift/Great Plains Seismic Transect (LA RISTRA) stations were computed using data from 1999 to 2000. At long periods (0.01-0.1 Hz), typical vertical n

Volcanic activity at Mount Erebus is dominated by eruptive activity within a phonolitic summit lava lake. Common eruption styles range from passive degassing to Strombolian explosions, which typically occur several times daily, and occasionally in sw

In December 1996 and January 1997, broadband seismometers were deployed on the summit plateau of Mount Erebus at radial distances of 0.7, 1.4 and 1.9 km from the central crater and lava lake. Strombolian explosions at Erebus previously have been obse

A prominent and spatially localized phase arriving approximately 4 s after the initial compressional arrival, repeatedly observed on seismograms recorded in the central Rio Grande Rift from intermediate- and deep-focus earthquakes at distances near 9

Fast directions and lag times associated with SKS shear-wave splitting are determined for six digital stations in the Rio Grande Rift (RGR). The mean fast direction for three stations in the central RGR is about 45° oblique to the axis of the RGR. I

Receiver functions constructed from teleseisms arriving from the northwest and recorded at station WTX in Socorro, NM show strong P-to-S conversions we interpret as coming from a mid-crustal sill-like magma body. Analysis of these conversions suggest

Summary. Inversion of 295. Love- and Rayleigh-wave phase travel times across the Pacific Basin has yielded a structure which has a channel that is anisotropic with respect to the polarization of shear waves. The velocity of SHwaves is approximately 4

Phase travel-times for Love and Rayleigh waves across the Pacific Basin were inverted to obtain models of the upper mantle of the Pacific Basin. Inversion of the Rayleigh wave data yielded a model with S-velocities in the lid and channel of 4.597 ±

SS phases from earthquakes on fracture zones near the Easter Island Cordillera and the West Chile Rise which are recorded in the United States have reflection points on either side of the East Pacific Rise (EPR) near the equator. The east-west record

262 P-wave arrival times associated with 40 local events obtained from a movable array of up to eight short-period seismographs were used to determine hypocentral parameters and an accurate three-dimensional seismic velocity model for the Rio Grande
