The GEO Geohazard Supersites and Natural Laboratories Initiative Objective, Status, Value Chart 1> Geohazard Supersites > Jörn Hoffmann Jörn Hoffmann German Aerospace Center (DLR) with contributions from: Michael Poland (USGS) and Freysteinn Sigmundsson (Univ. of Iceland) Supersites Coordination Workshop Brussels, June 10, 2013

Objective Chart 2> Geohazard Supersites > Jörn Hoffmann … 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 , 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.

How the Supersites work Chart 4> Geohazard Supersites > Jörn Hoffmann request  Free and open access to data for Supersites use

Types of Supersites Chart 5> Geohazard Supersites > Jörn Hoffmann 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

Permanent Supersite selection Chart 17> Geohazard Supersites > Jörn Hoffmann Scientist nominates Supersite Scientific Advisory Committee recommends new Site Supersites Steering Committee accepts Site Regular Review of continued relevance (every 2 years) Chair: Falk Amelung, Univ. of Miami Chair: Jörn Hoffmann, DLR

CEOS Selection Criteria  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 Chart 18> Geohazard Supersites > Jörn Hoffmann

Event Supersite selection Chart 19> Geohazard Supersites > Jörn Hoffmann SAC Chair, Steering Committee Member, or Permanent Supersite PI nominates Supersite Supersites Steering Committee accepts Site

CEOS Selection Criteria  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 Chart 20> Geohazard Supersites > Jörn Hoffmann

European Projects and the 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 Chart 21> Geohazard Supersites > Jörn Hoffmann

Summary on GSNL Chart 22> Geohazard Supersites > Jörn Hoffmann  support focused scientific research on geohazards  Initial sites selected  Evolving and maturing – EU projects contribute  Coming next:  More locations and hazards  More data resources  Computing platforms
