Recent Developments in High-Rate Geodetic Techniques and Network Operations for Earthquake and Tsunami Early Warning and Rapid Post-Earthquake Response [Poster]
Date: 4/25/2019
Room: Grand Ballroom
Over the past decade, geodetic techniques have become invaluable to rapid evaluation of earthquake hazards, both in real-time and for post-earthquake response. Techniques have included, but are not limited to, high-rate GNSS, strainmeters, ocean bottom pressure sensors, gravimeters and collocated seismic/geodetic instrumentation. These instruments and techniques are particularly useful for extracting moment release and rupture extent for large subduction earthquakes, although they have been shown to provide good source information for moderate sized events as well. Additionally, high-rate geodetic data and associated models can help improve ground motion characterization and prediction. This session seeks proposals that utilize geodetic instrumentation for the rapid modeling of earthquakes and tsunamis, both from the perspective of operational early warning and rapid post-earthquake response. We invite abstracts related to algorithm development, testing and validation of methodologies, machine-learning techniques to analyze GNSS data, analyses in combination with seismic data in real-time and more.
This session will also provide a venue for those involved in operating real-time GNSS networks to discuss current developments both in field operations and at data management centers. Building redundancy into critical data paths, efforts to lower latency and the upgrade of communications to meet the needs of systems being built for public-safety, methods for quantifying solution quality, as well seeking ways to integrate existing GNSS and seismic network infrastructure are topics of interest to this session. We also encourage presentations on the latest advances in the use of cloud architecture to manage the data and, the exploratory use of software such as Kafka and Elasticsearch at data operations centers.
