【 摘 要 】

This final report summarizes the accomplishments of the 2-year LDRD-ER project 'MEDIOS: Modeling Earth Deformation using Interferometric Observations from Space' (00-ERD-056) which began in FY00 and ended in FY01. The structure of this report consists of this summary part plus two separate journal papers, each having their own UCRL number, which document in more detail the major results in two (of three) major categories of this study. The two categories and their corresponding paper titles are (1) Seismic Hazard Mitigation ('Aseismic Creep Events along the Southern San Andreas Fault System'), and (2) Ground-based Nuclear Explosion Monitoring, or GNEM ('New Signatures of Underground Nuclear Tests Revealed by Satellite Radar Interferometry'). The third category is Energy Exploitation Applications and does not have a separate journal article associated with it but is described briefly. The purpose of this project was to develop a capability within the Geophysics and Global Security Division to process and analyze InSAR data for the purposes of constructing more accurate ground deformation source models relevant to Hazards, Energy, and NAI applications. Once this was accomplished, an inversion tool was to be created that could be applied to many different types (sources) of surface deformation so that accurate source parameters could be determined for a variety of subsurface processes of interest to customers of the GGS Division. This new capability was desired to help attract new project funding for the division.
