Zusammenfassung
High-precision real-time GNSS have recently expanded to monitoring and early detection of natural hazards. German research project EWRICA (Early-Warning and Rapid ImpaCt Assessment with real-time GNSS in the Mediterranean) funded by the national Ministry for Education and Research aims for the prototype implementation of the GNSS-augmented seismic source inversion and rapid impact assessment in the seismically active regions of Mediterranean. The project runs in close cooperation with partners operating high-rate GNSS networks RING (Italy) and NOANET (Greece). An overarching goal is to compute robust local ground motion models shortly after an earthquake to assess areas of strong shaking as well as secondary effects such as tsunamis and landslides. The four work packages - (1) real-time processing of coseismic displacements (RT-multi GNSS with regional augmentation, streamed in miniSEED format via SeedLink server, optionally joint processing with collocated accelerometers); (2) fast source inversion (Bayesian moment-tensor solution with Pyrocko tools); (3) rapid impact assessment (neural network predictions of ground motion maps with uncertainties, also coupled to probabilistic tsunami forecasting PTF at INGV); and (4) system prototype -- end up with an operational system prototype to demonstrate the full operational processing chain by hindcasting selected historical (e.g., 2016 M6.2 Norcia; 2020 M7 Samos) and synthetic event scenarios. EWRICA may serve as a blueprint for other regions of the world: currently EWRICA's tools are being tested for application in Indonesia, together with the colleagues from the Geospatial Agency (BIG) and from the national tsunami warning center InaTEWS.
