3 INTRODUCTORY REMARKS The entire Caribbean Basin is prone to socio-natural and man-made disasters ECLAC estimates that the disaster impact is over 1.5 billion US dollars/year A number of national, regional (ODPM, CDEMA, SRC, ACS) and international organizations (PAHO, OAS) are currently working in this area. Now we have GEM

30 THE GLOBAL EARTHQUAKE MODEL (GEM) A collaborative effort devised and launched by OECD s Global Science Forum, aimed at engaging the global community in the design, development and deployment of uniform open standards and tools for earthquake risk assessment worldwide

31 PUBLIC-PRIVATE PARTNERSHIP 10 countries have adhered so far discussions and negotiations are ongoing with 15+ others private organisations g have 7p partnered up with GEM so far they contribute 13.6 M Euro the OECD,, World Bank,, UNESCO,, UN/ISDR, IAEE and IASPEI are associate participants

32 SCIENTIFIC FRAMEWORK OF GEM Decision Making Tools Con ngency Planning, Territorial Planning, Cost BenefitAnal ysis, Ri sk Governance etc. Risk and Impact Analysis Damage and loss maps, loss exceedance curves, risk indicators, indirect losses, impact on society/ economy Hazard Probability, Intensity, Loca on Exposure Value, Loca on; Physical, Social, Economic Vulnerability Physical, Social, Economic, Ins tu onal; Func ons, Indicators

33 FIRST PRODUCTS What is? OpenQuake is an open source software application that allows users to compute seismic hazard and risk on any scale, developed as an open source project, available for download from

35 STAY UPDATED GEM Website Most update source of information News, results, calls, GEM Report 2009/2010 v2 Available from website and hard-copy GEM Brochure Available from website and hard-copy Bi-monthly e-newsletter Sign-up at website

36 LAUNCH OF GEM CARIBBEAN PROGRAMME -The development of Regional Programmes (RPs) is the main mechanism through which the GEM tools will be transferred with a view to creating a uniform globally used standard. The RPs involve local experts using GEM software and tools, who generate local data and validate the data and standards that are being created on the global level. -The Institution i of Structural Engineers (Caribbean Division) hosted a presentation of the GEM project at the Normandie Hotel in Trinidad on 15 October 2010.

37 LAUNCH OF GEM CARIBBEAN REGIONAL PROGRAMME (Cont ed) -In January 2011, the GEM Foundation (hereinafter referred to as GEM) engaged The Seismic Research Centre (SRC) of The University of the West Indies, St. Augustine, to promote the GEM vision in the Caribbean. Funding became available in March 2011 at which time the GEM Operational Manager, Dr. Myron Chin, was appointed. He will, in collaboration with all players/stakeholders from the Caribbean community, spearhead the implementation of the GEM initiative in the Insular Caribbean and the effective functioning of the GEM Regional Programme (RP) for the Caribbean

50 DEVELOPMENT OF CARIBBEAN RISK ATLAS FOR DEVELOPMENT OF CARIBBEAN RISK ATLAS FOR EARTHQUAKE HAZARDS (RISK ATLAS PROJECT)

51 DEVELOPMENT OF CARIBBEAN RISK ATLAS FOR EARTHQUAKE HAZARDS (RISK ATLAS PROJECT) Project Manager: U.W.I Disaster Risk Reduction Centre (DRRC) at Mona, UWI in Jamaica. Main Sponsor: World Bank Completion Date: December 2011.

52 OBJECTIVES To develop a methodology for seismic risk assessment in the Caribbean for three pilot States: Jamaica, Grenada and Barbados. To provide guidelines and open-source software for the estimation of earthquake loss using available socio-economic data.

53 Project Components Seismic hazard assessment for Jamaica in terms of PGA and spectral ordinates for 0.2s and 1.0s For Barbados and Grenada: we will use the seismic hazard results of the Eastern Caribbean Project (SRC/EUCENTRE). Development/Adapted Fragility Curves Modification, testing ti and validation of ELE software Determination of data requirements and collection of geo-referenced data Risk evaluation

55 SURVEY ON DECEMBER Kingston Precast houses Masonry Houses Reinforced concrete apartments Modern Reinforced Concrete Building at New Kingston Historical Buildings Reinforced concrete buildings on slopes Wooden house

56 DEVELOPMENT OF FRAGILITY CURVES FOR pre-cast thouses Heavy roof Connections between panels are effected by welding together matching metal angle sections embedded in the edge ribs of the panels.

57 FUTURE WORK GEM collaboration: - Collaboration with GEM in terms of assistance with the OpenQuake software development. - Two of our Research Assistants from SRC spent two months at the GEM Headquarters from end August to end October 2011 to learn about OpenQuake and to analyse the data collected under the DRRC Risk Atlas Project in order to assess its applicability to the Caribbean Region.

58 GROUP 5 EXPOSURE BUILDING CODES ONE GEM PROJECT IS A NATIONAL BUILDING CODE FOR T&T

59 GROUP 5 EXPOSURE BUILDING INVENTORY LEADER KEVIN GRANGER Project objectives 1. Develop a Crowdsourcing model which is appropriate to this Region and in keeping with GEM Standards. Crowdsourcing refers to the act of outsourcing tasks, traditionally performed by employees or contracted labour, to a relatively undefined, large group of people or community (a crowd ), through an open call. I have chosen to refine this Wikipedia definition to include the word relatively as the intention of this project is to break up the crowd into two categories. The Bounded Crowd will be those participators who will not have any specific experience in structural data collection and will be limited in the data that they can submit. These participators will be responsible for creating the Level 1 attributes as defined in the GEM Taxonomy. Level 1 attributes will be those attributes that are easily observable and will also include remote sensing, rapid assessments by municipalities (admin staff), engineers, architects, technicians, and social scientists. The Unbounded Crowd will therefore be those participators who will have had sufficient experience in structural data collection techniques to be responsible for submitting Level 2 attributes. These attributes will contain detailed structural and non-structural information obtained from a detailed building assessment by a qualified engineer. Partnership with GEM appointed agencies/tools or other groups like UShahidi hidi (see would allow us to create a web-based system that can assemble rank and filter the input from the crowd and present weighted results.

61 SOME EXAMPLES OF POTENTIAL USE OF GEM TOOLS AND MODELS IN THE CARIBBEAN. GEM s model and tools are envisaged to support a wide range of users, both from the public and private sectors, regional and national organizations, non-governmental bodies and also individuals id in earthquake prone areas. The following examples are some of the potential use of GEM tools and models:- A country s Minister of Planning and Development may wish to find out how the effect of different possible earthquake scenarios might affect the Gross Domestic Product (GDP) of the country. A national disaster organization would like to see the expected distribution of damage and fatalities within an urban area for a selected scenario earthquake for emergency management planning. A reinsurer or national primary insurer would like to calculate the average annual loss and probable maximum loss to a portfolio of buildings (based on their own input exposure data). A geologist would like to carry out a new tectonic analysis in proximity to a dam, and would like to download data on active faults as a starting point for his/her study. An engineer who is working on the design of a bridge located in a zone of seismic activity, would like to obtain uniform hazard spectra at different return periods for different performance limit states. An individual would like to understand how hazardous the area is, where (s)he is planning to build a house.

62 CONCLUDING REMARKS In concluding this Presentation, it is appropriate to make the following remarks- -GEM IS A GLOBAL ATTEMPT AT COLLABORATIVE DEVELOPMENT OF OPEN-SOURCE SOFTWARE, TRANSPARENT TOOLS AND MODELS FOR EARTHQUAKE RISK ASSESSMENT WORLDWIDE BY INVOLVING EXPERTS AND PROFESSIONALS FROM ALL REGIONS OF THE WORLD AND AS SUCH PROVIDES A CATALYST FOR EARTHQUAKE RISK REDUCTION NOT ONLY IN THE CARIBBEAN BUT THROUGHOUT THE REST OF THE WORLD -GEM IS NOT A VEHICLE TO CARRY OUT THE WORK OF MAJOR INSURANCE/REINSURANCE COMPANIES - GEM CARIBBEAN RP PROVIDES AN OPPORTUNITY TO BRING TOGETHER EARTHQUAKE RISK REDUCTION PROFESSIONALS FROM THE CARIBBEAN REGION TO WORK TOGETHER IN ADAPTING THE TOOLS AND MODELS DEVELOPED BY GEM SO THAT EARTHQUAKE RISK CAN BE BETTER ASSESSED IN THE VARIOUS ISLANDS OF THE CARIBBEAN.
