GNSS Seismogeodesy: Theory and Applications combines GNSS and seismology theory and applications to offer both disciplines the background information needed to combine forces. It explores the opportunities for integrating GNSS and seismometers, as well as applications for earthquake and tsunami early warning applications. It allows seismologists to better understand how GNSS positions are computed and how they can be combined with seismic data and allows geodesists to better understand how to apply GNSS to monitoring of crustal motion. GNSS Seismogeodesy is a valuable reference for researchers and students studying the interdisciplinary connection between GNSS geodesy and strong-motion seismology, as well as working on new approaches for monitoring and predicting geologic hazards. Bridges the gap for geodesists and seismologists to better understand how their fields can be complementary Offers an interdisciplinary approach to GNSS geodesy and strong-motion seismology, showing how high-precision GNSS positions can be combined with seismic data Covers the applications of seismogeodesy to earthquake early warning (EEW) and tsunami early warning (TEW) Includes algorithms and source code examples, as well as links to open source software and data sets

This dissertation presents a series of algorithms and plans for implementation of a prototype earthquake early warning system by merging two seismic observation tools: strong motion accelerometers and Global Navigation Satellite Systems (GNSS). The seismogeodetic approach, that which optimally merges these disparate data types, allows a reliable estimation of the earthquake source for early warning procedures from event detection to magnitude estimation and higher order products. We address implementation of this system in a real-time, automated environment, designed to operate without manual oversight. We assess the capabilities of low-cost micro-electro-mechanical systems (MEMS) accelerometers merged with observatory-grade GNSS for seismic P-wave detection, and suggest statistical methods to determine whether P-wave detections are consistent between stations, which allows for the automated removal of poor quality detections to avoid propagating these errors to higher order warning products. In line with these goals, we demonstrate how seismogeodetic observations contribute to our view of initial rupture dynamics of large earthquakes. We address an open question in seismology regarding the deterministic nature of earthquakes, assessing how early it is possible to fully characterize the source parameters of large, damaging earthquakes. Our seismogeodetic observations suggest that final earthquake magnitude is not discernable from the first few seconds of observation and therefore the earthquake rupture process is not strongly deterministic. We further investigate the complete temporal evolution of seismic moment release to identify the earliest magnitude-dependent features in our observational dataset. We create synthetic rupture models to identify the physical basis responsible for the timing of observed magnitude-dependent qualities. Our findings suggest that earthquake magnitude can be estimated prior to rupture completion, consistent with a weakly deterministic rupture process. These results provide new insights into the best practices for early warning and rapid response, and suggest limitations on the timeliness of earthquake source characterization. Finally, we turn to the built environment to demonstrate the applicability of these multi-instrument sensors to long-term structural health and seismic monitoring, to bolster earthquake and other natural hazard response practices. We describe efforts to characterize local buildings by creating a baseline model for the healthy structure and propose methods by which structural health can be evaluated over time or following a major seismic event to assess building safety without the need for manual inspection. We again assess the capabilities of low-cost MEMS accelerometers and describe the limitations of this lower-quality instrumentation for structural monitoring applications.

The Special Issue is focused on recent and upcoming advances in the combined application of remote sensing and applied geophysics. Applied geophysics analyzes the distribution of physical properties in the subsurface for a wide range of geological, engineering, and environmental applications at different scales. Seismic, electrical, magnetic, and electromagnetic methods are among the most applied and well-established geophysical techniques. These methods share the advantages of being non-invasive and exploring wide areas of investigation with respect to conventional methods (e.g., drilling). Geophysical surveys are usually carried out deploying or moving the appropriate instrumentation directly on the ground surface. However, recent technological advances have resulting in the development of innovative acquisition systems becoming more typical of the remote sensing community (e.g., airborne surveys). While applied geophysics mainly focuses on the subsurface, typical remote sensing techniques have the ability to accurately image the Earth’s surface with high-resolution investigations carried out by means of terrestrial, airborne, or satellite-based platforms. The integration of surface and subsurface information is often crucial for several purposes, including the processing of geophysical data, the characterization and time-lapse monitoring of surface and near-surface targets, and the reconstruction of highly detailed and comprehensive 3D models of the investigated areas. Recent contributions showing the added value of surface reconstruction and/or monitoring in the processing, interpretation, and cross-comparison of geophysical techniques for archaeological, environmental, and engineering studies are collected in this book. Pioneering geophysical acquisitions by means of innovative remote systems are also presented.
