Supersites Coordination Workshop
Brussels, June 10, 2013
Objective
www.DLR.de • Chart 2 > Geohazard Supersites > Jörn Hoffmann • 10.06.2013
… to reduce the vulnerability to geological hazards by improving the scientific understanding of hazardous events through worldwide scientific collaboration.
Supersites Strategic Plan (2011)
GEO Work Plan 2012-2015, Task DI-01-C2
Support the establishment of Supersites and Natural Laboratories.
Provide an electronic infrastructure allowing easy access to data (space & in-situ) and a wide range of tools, and a platform for on-line collaboration. Develop a consolidated Supersites Strategic Plan.
Objective
1. Global network of geohazard natural laboratories, consisting of sets of natural laboratories for Europe/Africa, the Americas and Asia/Oceania.
2. Seamless access to seismic, GNSS and SAR data for each of the natural laboratories.
3. Comprehensive multi-sensor SAR data acquisition plans: background acquisitions using low-resolution SARs and targeted acquisitions of specific sites using high-resolution sensors, maximizing the synenergy with in-situ networks.
4. Community-provided software applications for scientific data analysis using a Cloud e-infrastructure.

Types of Supersites
www.DLR.de • Chart 5 > Geohazard Supersites > Jörn Hoffmann • 10.06.2013
Permanent Supersites• Highest priority• Threat to humans and/or critical facilities• Scientific investigations aim at understanding processes
Candidate Supersites• … are Permanent Supersites under development.
Event Supersites• Recently affected by major geological event• important and rare opportunity for scientific investigation• Substantial scientific interest internationally
Natural Laboratories• Potentially larger areas• Potentially less densely monitored
