The Geohazards Community of Practice (GHCP) of the Group on Earth Observations (GEO) is an open community focused on support for Disaster Risk Reduction through Earth observations. In 2010, the GHCP drafted a Road Map, which addresses all four phases of the risk management cycle (preparedness, early warning, response, and recovery) and which has the goal to put in place the building blocks for risk management informed by Earth observations. In 2011, the GHCP organized the European Science Foundation conference on "Understanding Extreme Geohazards: The Science of the Disaster Risk Management Cycle." This conference resulted in a declaration, with a number of recommendations.

In the GHCP Splinter Meeting, we will discuss the implementation of the GHCP Road Map and address the recommendations developed during the ESF conference. A community white paper on extreme geohazards and the associated societal challenges is in preparation and the draft white paper will be presented and discussed. The organizers invite interested members of the GHCP and other participants to suggest presentations and contributions to the organizers of the splinter meeting.
