IGOS-P Geohazard Theme Added Value of GEO Political and material support: faster than for IGOS alone Better chances for long-term funding Series of regional Workshops (Asia, Africa) not without GEO, contact with developing countries significantly improved Improved capacity building Communication within governments greatly improved, particularly in the field of geohazards

Points for the Report 1. Community added value: Scientific advisory for a multi-risk approach in Geohazards 2. Community building: initial kernel of a GEO Community of Practice ; Regional initiatives in South East Asia and Africa; 3. User requirement process: Initial user requirements, compliant with the approach proposed by Hans-Peter in the "User Needs Facility" document. 4. Architecture and data interoperability: GeoHazData IGOS-P Geohazard Theme

Potential Event Merapi Volcano, Java: 2006 Eruption, Saturday, 13 May 2006: The scientists still cannot say when the volcano will erupt nor how powerful any explosion might be Wednesday, 7 June 2006: 2,000 people gather for safety in an Internally Displaced People (IDP) camp in Jumoyo, Jogjakarta August 2006:

IGOS-P Geohazard Theme Potential Event Merapi, one of Indonesia's most active volcanoes, dominates the landscape immediately north of the city of Yogyakarta in one of the world's most densely populated areas. Merapi is the youngest and southernmost of a volcanic chain extending NNW to Ungaran volcano. The steep-sided modern Merapi edifice, its upper part unvegetated due to frequent eruptive activity, was constructed to the SW of an arcuate scarp cutting the eroded older Batulawang volcano. Pyroclastic flows and lahars accompanying growth and collapse of the steep-sided active summit lava dome have devastated cultivated lands on the volcano's western-to-southern flanks and caused many fatalities during historical time. Since 1953, activity has been characterized by extrusion of lava into the summit crater, with periodic lava dome collapse and nuée ardente formation. Summit lava dome growth has continued since the 1969 gas explosion. It is monitored from the Merapi Volcano Observatory (MVO) in Yogyakarta.
