The GPS Shield: More Efficient and Effective Tsunami Early Warning
Abstract
Monitoring tsunami development and propagation via acoustically coupled Traveling Ionospheric Disturbances (TIDs) was proposed over fifty years ago. Remote monitoring of tsunami propagation via ionospheric perturbations captured the imagination of many. The capability and open availability of the GPS and its sister Global Navigation Satellite Systems and real time networks make it possible to observe some of the acoustic, seismic, and the electromagnetic disturbances associated with disturbance of the Earth's surface. This presentation will discuss the phenomenon, and the potential impact on the enhancement of safety for coastal communities.
Recent memories remind us of the suffering caused by past tsunamis. We propose an extension of the GPS Shield proposed by Sobolev et al (2007) to measure displacement and provide quantitative estimates of a resulting tsunami. GPS Shield was never realized, The new GPS (GNSS) Shield will also provide tsunami imaging of the development and propagation of the resulting tsunami. The GPS Shield enhance existing Tsunami early warning systems with a more accurate and complete tsunami early warning capability. GPS Shield will enhance our understanding of geodynamics, improve our response to Natural Disasters while also contributing to the economic development of the nations that it serves.- Publication:
