The Geohazards Monitoring Focus Area of the Global Geodetic Observing System (GGOS) seeks to apply geodetic science and technology in support of global and regional resiliency to environmental hazards.
The GGOS and its associated IAG services (International GNSS Service (IGS), International VLBI Service for Geodesy and Astrometry (IVS), International DORIS Service (IDS), International Laser Ranging Service (ILRS), International Earth Rotation and Reference Systems Service (IERS), and International Gravity Field Service (IGFS)) provide products that serve as the fundamental geodetic references for science, governments, and industry. The most notable of these products serve as the basic reference for positioning and timing information associated with the Global Navigation Satellite Systems (GNSS) including the International Terrestrial Reference Frame (ITRF), precision orbit and time information and continuing scientific and technical advancements to the utilization of the GNSS data. These and other GGOS products achieved wide global recognition and acceptance because of their accuracy, timeliness, and continuing technical improvements. These are the very qualities needed for effective environmental warning.
In some cases the acceptance of geodetic applications have been immediate and widespread such as the application of GNSS to understanding and modeling earthquake faults. However, in other cases geodetic technology has advanced faster than nations can utilize this new capability. The Geohazards Monitoring Focus Area seeks to accelerate and guide the acceptance of new geodetic capability to improve resilience to environmental hazards. The Focus Area will establish working groups comprised of GGOS members and the responsible agencies of participating nations. The Focus Area encourages the sharing of intellectual, financial and physical resources as recommended by the UN-GGIM (http://ggim.un.org ).
As its first initiative, the Geohazards Monitoring Focus Area has issued a Call for Participation (CfP) to research scientists, geodetic research groups and national agencies in support of the implementation of the IUGG 2015 Resolution 4: Global Navigation Satellite System (GNSS) Augmentation to Tsunami Early Warning Systems (http://www.iugg.org/resolutions/IUGGResolutions2015.p df). The CfP responders will comprise a working group to be a catalyst and a motivating force through the definition of requirements, identification of resources, and the encouragement of international cooperation in the establishment, advancement, and utilization of GNSS for Tsunami Early Warning, The initiative will have early focus upon the Indo-Pacific region following the IUGG 2015 Resolution 4. Future working groups of the Geohazards Monitoring Focus Area will support compelling initiatives that improve the resiliency of global and regional societies through the application of geodetic science and technology. The working groups mandate will be to develop an attainable and valuable goal as recommended by the GGOS Science panel. Each working group will define a work-plan with an estimated time line that will be subject to periodic review by the GGOS Coordinating Board.
