SM2.3 | Advancing Science with Global Seismological and Geophysical Networks


Four decades of globally distributed and openly available very broadband seismic recordings have enabled significant advances in characterizing earthquake sources, mapping the deep structure of the Earth, and understanding the behavior of the atmosphere, hydrosphere, and cryosphere. Long-term deployment has illuminated time-dependent processes and allowed subtle signals to be enhanced and utilized through stacking. At the same time, establishing real-time telemetry at these stations has revolutionized the monitoring capability for large and potentially destructive earthquakes. Central to these activities have been the international partnerships, infrastructure investments, and technological developments that have facilitated, grown, and maintained the availability of low-noise and high-fidelity seismic recordings from almost anywhere in the world.

This session will be a forum to highlight impactful current science being done with globally distributed real-time networks, to understand how technological developments can optimize existing resources, to share ideas for expanding networks like the Global Seismographic Network, GeoScope, and others to include other geophysical and environmental observations, to recognize how increased partnerships and collaboration can further grow high-quality station coverage around the world, and to reflect on the common challenges to operating and sustaining these scientific resources.

We encourage contributions from the international community of seismologists and related disciplines, instrumentation developers, network and station operators, and other stakeholders.

Convener: Frederik J. Simons | Co-conveners: Martin Vallée, Frederik Tilmann
