1. The Geohazard Supersites initiative improving DRR through better science
Stefano Salvi
Chair of the GSNL Scientific Advisory Committee

2. The GEO-GSNL initiative
An international partnership aiming to improve, through an Open Science approach, monitoring and research on seismic/volcanic interest areas called Supersites, providing better scientific information support for DRR.
The partnership
The scientific community
The in situ data providers
The satellite data providers

3. The role of scientists
Understand the When, Where, How of Disaster occurrence (Hazard & Risk assessment)
Ensure proper and timely communication of scientific information to decision-makers (Sendai framework)

All Supersites are managed by institutions which have a formal mandate for providing scientific support to local DRM agencies

5. How Supersites contribute to DRM
Satellite data and ground data are made available by the CEOS and by local monitoring agencies
Research is carried out by the international scientific community and new science is openly shared within the community
A consensus process driven by the Supersite Coordinator is used to generate synthetic scientific information products
Local decision makers receive the scientific reports from the Supersite Coordinator
Decisions are taken based on these products, to support Risk Prevention/Mitigation or Emergency management

6. EO data
Only two space agencies directly provide EO data through web services: DLR and ESA
CSK and Radarsat (in the future also Pleiades/SPOT5) data are presently accessed offline, but in some cases they are provided online through community platforms as the ESA GEP or the UNAVCO SSARA

7. In situ data
Seismological data (waveforms, earthquake locations, etc.) are provided as web services by IRIS, for most Supersites
GNSS data are provided as web services by UNAVCO GSAC for some Supersites, or offline.
Some Supersites provide access to several other datasets but not through web services

11. The GSNL essential datasets for GCI
Seismological data: waveforms, hypocentral locations, magnitudes, focal solutions
Geodetic data: raw (rinex format), station coordinates, displacements, velocities, time series
EO data products (e.g. not SAR images but ground displacements/velocities)
Geological maps
