Central America Mexico Caribbean. Names…. Central America, Mexico, Caribbean. Challenges Data exchange Intra-regional scientific cooperation Science: Moving beyond routine monitoring Increasing the number of geophysicists in the region Solutions and Proposals - PowerPoint PPT Presentation

    Solutions and ProposalsFraming New Proposals (Hazard, E&O, Science)Funding Partners & ContactsIdentifying Regional Institutions

  • Lessons from AfricaArrayEconomic drivers Mining and oil industries (provide funding and employment)Only Mexico, Venezuela and Trinidad and Tobago have significant oil industries in this region

    Other driversMuch greater seismic risk than AfricaDisaster mitigation/earthquake monitoring are bigger concerns

    Might provide similar appeal to Latino US students as AfricaArray provides to African American studentsCould frame proposals as minority E&O to attract US Latino students

    Capacity-building efforts conducted in-country, rather than in USDifferencesmany small, diverse, far-flung countries, no South Africa BUT probably have greater expertise in the region than in much of Africa

  • Data ExchangeAppears to be a problem with concept of open data exchange.Regional Data Centers vs. IRIS DMCFrame IRIS DMC as an opportunity to back up data securely, organize metadata, distribute data and metadataPropose a multi-tier data release policy, e.g., data for events above a certain threshold would be released immediately, other data would be released after 2-3 yearsPerhaps tie other efforts (research collaborations, communications upgrades, etc.) to commitment to contribute data under this policy

  • Challenges for increased cooperation & data exchangePolitical issues national autonomy, local operators need to justify their effortsGeography many far-flung countries/islandsLanguages Spanish, English, FrenchResponsibility need to avoid conflicting reports & event solutionsDiverse, inconsistent helptraining programs provided by various groups in various softwareleads to inconsistency of formats and results.

  • Possible SolutionsEnsure broad participation need to be inclusive of all stakeholdersPromote role of local institutionslocal networks, local geoscience programs, govt agenciesCould IRIS support technical consultants to help with software/hardware needs (configuration, programming, design of acquisition system, conversion scripts/software, etc.)?

  • Increasing the number of geophysicists in the regionVery few universities in the region offer geophysics degrees.Lesson from AfricaArray: Education and training are tied to development of BB network and are performed in countryStart with internships and/or field camps (e.g., SAGE)Potential funding sources: OAS? Fulbright? Private foundations? Oil companies? Can we get companies to contribute to a fund that will support geophysical education without specific quid pro quo considerations?Can we emulate the IRIS internship program within Latin America and the Caribbean?Who would teach at field camps? Where would internships take place?

  • Monitoring & Hazard AssessmentLocal faultinglarge magnitude earthquakes can be produced by local faultsnot just major subduction zonesNeed high resolution bathymetry for tsunami forecastingMonitoring faultsneed to know rate of movementcontinuous GPS studiesSeismic gaps/risk (NSF probably would not consider this a basic science question)

  • Research:Moving beyond routine monitoringCentral America is already a MARGINS focus site."models of upper plate deformation"How does subducting plate interact with over-riding plate?Models of upper plate deformation and how it couples to variations in subducting slab (age, subducting seamounts, etc.)Caribbean puzzlesNeed to understand morphology of downgoing plateWhat is the origin of the Caribbean plate and what is nature of lower crust?Is Cocos ridge beginning of subduction?Link between subduction earthquake and subsequent (several months later) local event which causes most of the damageneed stress modeling. Highlights importance of local earthquakes.Flat slab subduction

    Assets needed/availableOcean bottom seismographsLong-term GPS monitoringNeed a pool of temporary instrumentsseismic and GPS (partnership with UNAVCO?) Chikyu riser drilling ship will need another target after it finishes drilling offshore Japan

  • Funding partners & contactsNational & Regional FundingMexico and Venezuela seem to be the only ones with a significant "NSF" equivalentbut are unlikely to support regional efforts (outside their home countries)Mexico funds projects up to $500K "National Council for Science and Technology" the problem is, once you get money for equipment, that's itno more funding for operations, data analysis, etc. funding availability varies from country to country but more is needed

    Aid agencies (e.g., USAID, World Bank)Requests need to come from countries in region, rather than from US research communityWe could help coordinate proposals and provide technical consulting for networksA project/proposal coordinated between a majority of countries in the region would probably be viewed favorably

  • Funding partners & contacts (2)Electric companies?ICE funds earthquake monitoring in Costa RicaAre there any new nuclear power plants planned for the region?Insurance companies?Potential for catastrophic losses is great

    US-based fundingLimitations of research funding (US citizens, short-term, wont pay for permanent equipment, not interested in monitoring)How can we facilitate?Perhaps as a matchmaking serviceto connect potential US and Central American and Caribbean PIs.

    IRIS could conduct regional workshops to develop research proposals of mutual interest.

  • Intra-regional scientific cooperationNeed consortium toconduct regional science workshopsprovide robust, documented softwarecoordinate data exchanges/archivingprovide consultation for networks & equipment


  • InstitutionsCentral American Seismic Center (CASC) Collects dataincluding waveform and phase datafrom all Central American nationsUniv of Costa Rica supplies funding for the one person who works at CASCUPRM - Puerto Rico Seismic Network Has stable funding, established network, technical staff, bilingual personnel, associated with degree-granting departmentSRU Seismic Research Unit of the University of the West IndiesMonitors seismic and volcanic activity in English-speaking Eastern CaribbeanHas stable funding involving 8 statesCEPREDENACBegan as a scientific/technical organization but has lost that focus

  • Work PlanConduct inventory of stations, networks, personnel(Include detailed characteristics of instruments (type, short-period, long-period, BB, three-comp't), resolution of digitizer, how data are delivered, sample rates, etc.)Identify stations/equipment that could be upgraded, repaired, or refurbished with a little money and then, perhaps, tie upgrade funds to commitment to contribute data.Hold a workshop this year to hash out science problems and write a proposal. Target is NSF's PIRE program, plus oil companies, and will facilitate proposals to USAID from the region's countries themselves.

  • Station inventory

  • Need names & addressesPlease send email to Lindsay Wood if you would like to be kept informed of progress of this working group

    Seismic stations in the MIDAS region in the last forty years. Most of the stations that have reported to the ISC (yellow squares) are no longer operating, but data from the time periods in which they were operating are, in many cases, still available. IRIS PASSCAL deployments are typically for time periods of 1-2 years, so data from these stations will be limited. Stations indicated on the map are comprised almost exclusively of weak motion seismometers: short, intermediate, and broad frequency passbands and either one or three-components.
