IGOS-Geohazards

IGOS-Geohazards is concerned by all natural hazards that

originate from the Solid Earth such as Earthquakes,

Volcanoes, Ground Instabilities (i.e. landslides,

subsidence, collapse, rock falls, shrinkage/swelling of

soils, etc…) but also Tsunamis

IGOS Geohazards: past work and current status

> UNESCO, CEOS and ICSU initiated and scoped the IGOS Geohazards Theme in 2001.

> An Ad-hoc Working Group was formed, held an international workshop in Frascati (Rome), and delivered a proposal to the IGOS partnership in May 2002.

> The resulting IGOS Geohazards Theme Team delivered a Theme Report to the IGOS Partners in May 2003.

> Following an international peer review, the Geohazards Theme Report was published in April 2004.

http://www.igosgeohazards.org

IGOS Geohazards: Context (1/3)

> Theme report proposed a strategy structured by five elements of critical importance to the Geohazards:• Underpinning Science

• Observations

• Modelling and Integration

• Infrastructure and Access

• Capacity Building

> One recommendation was the setting up of a Geohazards Bureau to monitor and coordinate implementation

> The IGOS Geohazards Bureau created by the BRGM (French Geological Survey) and the European Space Agency (ESA) in last quarter 2004 initially for a three year

period ([email protected]).

> GEOSS : Global Earth Observation System of

Systems

• Newly established GEOSS Secretariat in Geneva

• Geohazards included in the “Disasters” Societal Benefit Area,

which is of paramount importance for GEOSS.

> National, Regional and International initiatives

> Proposals from learned international associations

IGOS Geohazards: Context (2/3)

> Recent tragedies:• Bam Earthquake : about 40 000 killed (Dec 2003)

• Indian Ocean Tsunami : more than 200 000 killed (Dec 2004)

> Frequent disasters:• Landslides, rock avalanches, debris flows, …

• Moderate earthquakes and volcanic eruptions

• Subsidence

• Swelling- Shrinkage of Clays

together with concentration

of populations in risk prone areas

IGOS Geohazards: Context (3/3)

IGOS Geohazards: Objectives (1/3)

1- Bring together the actors from the Geohazards

community across different disciplines

(Earthquakes, Volcanoes, Ground Movement) and

methods (in-situ measurements - remote sensing,

modeling,...) with the aim of

– stimulating co-operation

– generating synergy

2- Gather information on the state of the art in

–observations

–modelling, data analysis

– infrastructure and data dissemination

–capacity building

This information will come from the community

and be made available to the community (via

the web).

IGOS Geohazards: Objectives (2/3)

3- Evaluate gaps between existing and needed tools with respect to

–observations

–modelling, data analysis

– infrastructure and data dissemination

–capacity building

for all Geohazards

4- Establish priorities

5- Provide recommendations for filling gaps in an optimal way

IGOS Geohazards: Objectives (3/3)

IGOS Geohazards: Strategy (1/2)

1- GeoHazNet : a Geohazards Network• A forum within which the Geohazard related disciplines can meet, exchange and propose

joint projects

• A cross-disciplinary approach with continental and sub-continental ramifications (Africa, Asia,

Australia, Europe, Middle East, North and South America)

• Hazard Focused (as compared to International Associations such as):

– International Association of Seismology and Physics of the Earth's Interior ( IASPEI),

– International Association for Earthquake Engineering (IAEE).

– International Association of Volcanology and Chemistry of the Earth's Interior ( IAVCEI),

– International Consortium on Landslides (ICL),

– International Society of Soils Mechanics and Geotechnical Engineering (ISSMGE),

– International Society for Rock Mechanics (ISRM),

– International Union of Soil Sciences (IUSS),

– International Union of Geological Sciences (IUGS),

– International Association for Engineering Geology and the Environment (IAEG),

– International Association for Mathematical Geology, (IAMG),

– International Union of Geodesy and Geophysics (IUGG),

– International Geographical Union (IGU),

– Etc…

IGOS Geohazards: Strategy (2/2)

2- Provide the infrastructure for stimulating co-operation and

generating synergy by means of :

– working groups

– events such as international workshops, ….

– website and other dissemination activities

3- Promote results through information dissemination among

end-users, decision makers and other dedicated structures

IGOS Geohazards Working Groups

> Science : the state of the art and attended evolution

> Observations: existing and expected observing tools

> Infrastructure: structures/techniques for

data/information storage/dissemination

> Integration: data processing, interpretation,

modeling, fusion..

> Capacity Building: facilitating knowledge transfer

IGOS Geohazards Working Groups (detailed 1/5)

> Science • Addresses principally the fundamental research and

provides input for Observations and Integration WGs

Considers

• fundamental research to identify the measurement of new parameters that may help improve understanding of Geohazards phenomena

• fundamental research into modeling or data fusion for the generation of information products

IGOS Geohazards Working Groups (detailed 2/5)

> Observations • Addresses principally observing tools, their accuracy and

other characteristics (frequency, …)

Considers

• satellite, in-situ and airborne data that is used for Geohazard mitigation

• Mainly in-field measurements building on already extensive work on satellite based data

• data as being “well-established” not experimental in nature - this is included in Science WG

but

• the synergy generated between different data types is NOT considered here but in Integration WG

IGOS Geohazards Working Groups (detailed 3/5)

> Infrastructure • Addresses principally the support structures and

techniques

Considers

• Structures and techniques that allow dissemination of data, tools and information on Geohazard mitigation

• Databases and associated technology

• System interoperability, ancillary data and meta-data requirements

• Networks of sensors

• Delivery of information to end-users such as decision-makers in a timely fashion

IGOS Geohazards Working Groups (detailed 4/5)

> Integration• Deals with data

Considers

• data processing methods: qualitative interpretation, multi-parametric data analysis, modeling

• fusion of different data streams

• extracting information from data

but

• “systems” aspects such as interoperability are considered by the Infrastructure WG

IGOS Geohazards Working Groups (detailed 5/5)

> Capacity Building • Deals essentially with knowledge transfer

Considers

• means for the consolidation of an international Geohazards community through existing associations and programmes

• mechanisms for developing Geohazard mitigation globally

• facilitating knowledge transfer in data integration

• Identification of appropriate infrastructures and dissemination technology to develop capacity under different circumstances (geographical and disciplinary gaps)

IGOS Geohazards Workshop - Outputs

> Clear terms of reference for each of the working groups

> Detailed planning with description of any individual contribution

> Proposal for enlargement of working group teams

> Recommendations for GeoHazNet extension to outside Europe

> Effective proposals for GEOSS 2006-2007 work plan

IGOS Geohazards Workshop Outputs detailed (1/2)

> A1- Define a Sampling Strategy in time/ space/ resolution/ accuracy/ scale covering both background monitoring and crisis response. Prioritise on risk versus reward basis.

> A2- On the basis of the Sampling Strategy, define Observational Requirements across all platforms for earthquakes, volcanoes, ground instability and tsunami. Feed this into IGOS Partners’ database managed by WMO.

> A3- Analyse current and future means (techniques or systems) for quantitative deformation measurement and their suitability to the geohazards

> A4- Identify one community test site for each geohazard and document the data available. Propose cross-validation activities.

> A5- Compile and maintain an inventory of existing materials (tutorials, courses), programmes and training infrastructure (e.g. regional/national centres)

> A6- Identify and structure list of geographical zones and concerned geohazards where capacity building activities must be developed in the short term.

IGOS Geohazards Workshop Outputs detailed (2/2)

> A7- Identify existing regional/global archives of data (including hazard maps) and historical events. Facilitating access to this resource through the web should allow:• Rapid access to existing data

• The development of baseline states for anomaly detection

• Stimulation of continuity in data acquisitions

> A8- Identify projects working in the area of data harmonisation/interoperability for the geohazards. Propose a interoperability demonstrator on databases that would benefit from being linked together through interaction with the appropriate projects

> A9- Inventory and develop contacts with projects employing a multidisciplinary approach to the integration of different data sources in the geohazards.

> A10- Identify and evaluate existing multihazard approaches used in information products for end-user landuse planning and decision support systems.

Proposed way forward

> The databases to be developed for inventory purposes:

• Data Needs (A1 and A2)

• Existing Capacity Building resources (A5)

• Existing archives of data and historical event (A7)

• Projects – containing three parts: interoperability/harmonisation(A8);

multidisciplinary approach to data integration(A9); multihazard approach(A10)

> Analysis tasks are the following:

• Quantitative Deformation measurement: Analyse current and future means

(techniques or systems) and their suitability to the geohazards (A3)

• Identify one community test site for each geohazard and document the data

available. Propose cross-validation activities. (A4)

• Identify and structure list of geographical zones and concerned geohazards

where capacity building activities must be developed in the short term. (A6)
