From Dense Seismic Monitoring to Mass-Movement Hazards and Their Impacts: Demonstrating an Operational Workflow and Associated Data Services

Description: 

We present and discuss a seismological workflow that uses rapid ground shaking information from ShakeMap (https://usgs.github.io/shakemap/) as input to the calculation of mass-movement hazards and their possible impacts on lifelines. The workflow is demonstrated in the Swiss Alpine region, where the Swiss Seismological Service (SED) at ETH Zürich (http://www.seismo.ethz.ch/en/home/) presently operates real-time nation-wide seismic monitoring networks comprising more than 75 broadband, 193 strong-motion, and 23 short-period sensors (e.g., CH network: https://doi.org/10.12686/SED/NETWORKS/CH; other networks at https://networks.seismo.ethz.ch/), along with a portfolio of real-time and rapid earthquake products including ShakeMap (https://doi.org/10.1785/0220220087). ShakeMap is used in this application as ground shaking information input to the calculation of mass-movement occurrence probabilities - made available as ShakeMap-associated products - which are in turn convolved with lifeline exposure data to estimate possible impacts along with costs and benefits of selected mitigation actions during an ongoing earthquake sequence. Based on free and open source software frameworks, the strategy to calculate ground-shaking and mass-movement hazard information is highly portable to other and broader contexts, and interoperability is being established with the European ShakeMap framework (https://doi.org/10.5194/egusphere-egu23-5937) within ongoing national and EC projects (e.g. https://www.geo-inquire.eu/).
