seismic waves, providing new insights and interpretation techniques into complex wave propagation effects. Using signals recorded by the array of seismometers, the EarthScope project will be able to animate seismic waves as they sweep across the USArray transportable array for selected larger earthquakes. This will be able to illustrate the regional and teleseismic wave propagation phenomena. The seismic data collected from both permanent and transportable seismic stations will be used to provide these computer generated animations. Regional Moment Tensors The seismic moment tensor is one of the fundamental parameters of earthquakes that can be determined from seismic observations. It is directly related to earthquake fault orientation and rupture direction. The moment magnitude, Mw derived from the moment tensor magnitude, is the most reliable quantity for comparing and measuring the size of an earthquake with other earthquake magnitudes. Moment tensors are used in a wide range of seismological research fields, such as earthquake statistics, earthquake scaling relationships, and stress inversion. The creation of regional moment tensor solutions, with the appropriate software, for moderate-to-large earthquakes in the U.S. will be from USArray transportable array and Advance National Seismic System broadband seismic stations. Results are obtained in the time and the frequency domain. Waveform fit and amplitude-phase match figures are provided to allow users to evaluate moment tensor quality. Geodetic Monitoring of the Western US and Hawaii Global Positioning System (GPS) equipment and techniques provide a unique opportunity for earth scientists to study regional and local tectonic plate motions and conduct natural hazards monitoring. Cleaned network solutions from several GPS arrays have merged into regional clusters in conjunction with the EarthScope project. The arrays include the Pacific Northwest Geodetic Array, EarthScope's Plate Boundary Observatory, the Western Canadian Deformation Array, and networks run by the US Geological Survey. The daily GPS measurements from ~1500 stations along the Pacific/North American plate boundary provide millimeter-scale accuracy and can be used monitor the displacements of the earths crust. With the use of data modeling software and the recorded GPS data, the opportunity to quantify crustal deformation caused by plate tectonics, earthquakes, landslides and volcanic eruptions will be possible. Time-dependent Strain The goal is to provide models of time-dependent strain associated with a number of recent earthquakes and other geologic events as constrained by GPS data. With the use of InSAR (Interferometric Synthetic Aperture Radar), a remote-sensing technique, and PBO (Plate Boundary Observatory), a fixed array of GPS
