Previous Supersites

Warning: this is the legacy website of the Geohazard Supersites and Natural Laboratories - GSNL initiative. We stopped updating it in 2014. Our official website is now geo-gsnl.org

The Supersites have data for the study of natural hazards in geologically active regions, including information from Synthetic Aperture Radar (SAR), GPS crustal deformation measurements, and earthquakes. The data are provided in the spirit of GEO, ESA, NASA and the National Science Foundation (NSF), that easy access to Earth science data will promote their use and advance scientific research, ultimately leading to reduced loss of life from natural hazards.

Supersites is an initiative of the geohazard scientific community. The Supersites provide access to spaceborne and in-situ geophysical data of selected sites prone to earthquake, volcano or other hazards. The initiative began with the "Frascati declaration" at the conclusion of the 3rd International Geohazards workshop of the Group of Earth Observation (GEO) held in November 2007 in Frascati, Italy. The recommendation of the workshop was “to stimulate an international and intergovernmental effort to monitor and study selected reference sites by establishing open access to relevant datasets according to GEO principles to foster the collaboration between all various partners and end-users”. This recommendation is formalized as GEO task DI-09-010.

For more information on Supersites please contact the Chair of the Scientific Advisory Committee Stefano Salvi at the INGV (stefano.salvi@ingv.it) or Francesco Gaetani at the GEO Secretariat (fgaetani@geosec.org).

Permanent Geohazard Supersites

Geohazard Supersites were selected for scientific reasons but also to maximize the visibility of the project. It is clear that, for example, a better understanding of the seismic hazard of Etna and Sinabung not only the study of these particular sites but also of vocanoes around the world.

Event Supersites

Previous Supersites and Other Events

    Previous supersites include events like Tohoku-oki, and regions like Seattle, which were never officially declared supersites by GEO.

    Other events are significant earthquake or volcanic eruptions that affected less than one million people .
