Abstract We present new 3‐D P wave and S wave velocity models of the upper 20 km of the Mount St. Helens (MSH) region. These were obtained using local‐source arrival time tomography from earthquakes and explosions recorded at 70 broadband station

This study uses a combination of absolute and relative locations from earthquake multiplets to investigate the seismicity associated with the eruptive sequence at Mount St. Helens between September 23, 2004, and November 20, 2004. Multiplets, a promi

We simultaneously invert travel times of refracted and wide-angle reflected waves for three-dimensional compressional-wave velocity structure, earthquake locations, and reflector geometry in northwest Washington state. The reflector, interpreted to b

Recordings of the 1999 M w 7.6 Chi-Chi (Taiwan) earthquake, two local earthquakes, and five blasts show seismic-wave amplification over a large sedimentary basin in the U.S. Pacific Northwest. For weak ground motions from the Chi-Chi earthquake, the

The Seattle fault, a large, seismically active, east-west-striking fault zone under Seattle, is the best-studied fault within the tectonically active Puget Lowland in western Washington, yet its subsurface geometry and evolution are not well constrai

Seismic P-wave velocity structure is estimated for the Puget Sound basin region using iterative, non-linear tomographic inversion based on finite-difference travel-time calculations. Local earthquakes and explosion arrival times are used to image the

A two-dimensional seismic P wave velocity model, extending to a depth of ∼50 km, is interpreted for a 425 km long profile extending from Hood Canal in western Washington across the central Cascade Range to Walla Walla in eastern Washington. Existin

Most marine sediments exhibit transverse isotropy (TI) that can have a significant effect on the signal properties of strongly bottom interacting sound. Locally, transverse isotropy has the greatest effect on the fundamental and near fundamental moda
