Integrated Global Observing Strategy: Geohazards

The Integrated Global Observing Strategy (IGOS) seeks to provide a comprehensive framework to harmonize the common interests of the major space-based and in-situ systems for global observation of the Earth. It is being developed as an over-arching strategy for conducting observations relating to climate and atmosphere, oceans and coasts, the land surface and the Earth's interior. IGOS strives to build upon the strategies of existing international global observing programmes, and upon current achievements. It seeks to improve observing capacity and deliver observations in a cost-effective and timely fashion. Additional efforts will be directed to those areas where satisfactory international arrangements and structures do not currently exist.

The IGOS Geohazards Theme is a combined initiative of UNESCO and two other IGOS members, the Committee on Earth Observation Satellites (CEOS) and the International Council for Science (ICSU). The IGOS Geohazards theme intends to respond to the scientific and operational information needs for the prediction and monitoring of geophysical hazards, namely earthquakes, tsunamis, volcanoes and ground instabilities.

The IGOS Geohazards Theme report 2004 identified five objectives.

  • Capacity building concerning consolidation of the global geohazard community of scientists and operational actors and outreach to support participation of geohazard professionals in developing countries.
  • Observations and key systems concerning current and future measurement technology both in situ and satellite based.
  • Modelling and integration concerning the systems (methods, software) used to integrate measurement data of different types and to undertake modelling of the phenomena that cause geohazards.
  • Infrastructure (databases) and access for geohazard professionals (both scientific and operational) to observations and tools (modelling and integration).
  • Underpinning Science concerning the fundamental scientific understanding of the phenomena that cause Geohazards.
