Geohazards

Chair: J. LaBrecque (USA)

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.
