Seismic Cycles Webinar Series

Join us for a special webinar series on seismic cycles. Starting May 6 through July 2022, the series will address the observations and physical processes that are important to consider in computational models. See the Calendar for more information on individual events. See Webinars for more information on the entire series.

Research Highlight

Representation of the unified and interconnected SCOPED Cyberinfrastructure. At the top, the global map of seismic stations represents one of several featured sources of data sets. Data are hosted and processed on HPC and on Cloud clusters, which overlie pillars of wavefield simulations (left column) and data processing and analysis (right column). Cross-disciplinary research will facilitate the investigations of outstanding questions about Earth and fault dynamics.

Seismic waves are our primary tools to explore the multi-scale structure of Earth— from its surface down to the inner core—and its wide range of processes, including earthquakes, volcanic activity, glacial processes, oceanic and environmental processes, and human-caused processes such as hydraulic fracturing or nuclear explosions. 

The unprecedented growth of data and computational power have formed two pillars of seismology during the last decade. While numerical tools allow us to take full 3D complexity of wave propagation in seismic source and structural modeling, exponentially grown seismic data from traditional broadband seismometers as well as emerging instruments (i.e., distributed acoustic sensors, MERMAIDs, nodal arrays, etc.) offer new opportunities to monitor seismic activity and to improve resolution beneath continents and oceans. We need high-performance and Cloud computing to efficiently process large data sets and accurately model them. Seismic workflows involve .... [cont]
