  1. > Geohazard Supersites > Jörn Hoffmann • 10.06.2013 The GEO Geohazard Supersites and Natural Laboratories InitiativeObjective, Status, Value Jörn Hoffmann German Aerospace Center (DLR) withcontributionsfrom: Michael Poland (USGS) andFreysteinnSigmundsson (Univ. ofIceland) Supersites Coordination Workshop Brussels, June 10, 2013

  2. > Geohazard Supersites > Jörn Hoffmann • 10.06.2013 Objective … to reduce the vulnerability to geological hazards by improving the scientific understanding of hazardous events through worldwide scientific collaboration. Support theestablishmentof Supersites and Natural Laboratories. Provide an electronic infrastructureallowingeasy accesstodata(space & in-situ) and a widerangeoftools, and a platformfor on-line collaboration. Develop a consolidated Supersites Strategic Plan. Supersites Strategic Plan (2011) GEO Work Plan 2012-2015, Task DI-01-C2

  3. > Geohazard Supersites > Jörn Hoffmann • 10.06.2013 Objective • Global network of geohazard natural laboratories, consisting of sets of natural laboratories for Europe/Africa, the Americas and Asia/Oceania. • Seamless access to seismic, GNSS and SAR data for each of the natural laboratories. • 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. • Community-provided software applications for scientific data analysis using a Cloud e-infrastructure. Task Sheet, GEO Task DI-01-C2

  16. > Geohazard Supersites > Jörn Hoffmann • 10.06.2013 CEOS SelectionCriteria • Geohazard threatens human population or infrastructure • subject to investigations aimed at broadening scientific understanding • Substantial interest of a broad scientific community • Support by the country – or countries – in which the Supersite is located • Availability of relevant in situ data • Dis-similarity to already existing Supersites • Ability to provide sufficient remote sensing satellite resources to make a meaningful contribution • Single PoC identified and committed

  17. > Geohazard Supersites > Jörn Hoffmann • 10.06.2013 Event Supersite selection SAC Chair,SteeringCommittee Member, or Permanent Supersite PI nominates Supersite Supersites SteeringCommitteeaccepts Site

  18. > Geohazard Supersites > Jörn Hoffmann • 10.06.2013 CEOS SelectionCriteria • recent earthquake, severe volcanic unrest or similar • important and rare opportunity for research • event motivates substantial scientific interest and investigations • Event Supersite benefits from space and in situ data made available

  19. > Geohazard Supersites > Jörn Hoffmann • 10.06.2013 European Projects andthe GSNL MARsite, FUTUREVOLC, MED-SUV are contributions to the GEO GSNL The projects • make use of and benefit from the GSNL • may supply the Supersite PI • Point-of-contact for Supersite – goes beyond EU project! • Interface to CEOS agencies • organize data access within the Supersite science team

  20. > Geohazard Supersites > Jörn Hoffmann • 10.06.2013 Summary on GSNL • supportfocusedscientificresearch on geohazards • Initial sitesselected • Evolvingandmaturing – EU projectscontribute • Coming next: • More locationsandhazards • More dataresources • Computing platforms
