  1. Delivering real-time, advanced satellite products and modellingsupport to volcano monitoring and prediction Steve Tait, IPGP Susan Loughlin, BGS-NERC Evoss team, (particularthanks to BGS team)

  2. EVOSS Targets • to assist in VOLCANO CRISIS MANAGEMENT • Particularly to provide real-time observation support to volcano observatories or mandated institutes • When there is little or no ground-based monitoring • Focus from SUSTAINED UNRESTTO ERUPTION • Capacity to deal withSEVERAL CRISES AT ONCE • For LONG LASTING (months to years) and SPATIALLY SCATTERED CRISES • VERY-HIGH TEMPORAL RESOLUTIONis given priority over high spatial resolution, a methodological breakthrough towardsREAL-TIME OPERATIONS • SUSTAINABILITY AND TIMELINESS OF OPERATIONS is a priority

  3. EVOSS User-Driven Objectives • To develop services within the framework of the EU FP7 GMES programme to respond to major volcanic activity • To deliver appropriate EO products in formats that are useful and usable for observatories and other authorities via the Virtual Volcano Observatory web portal • To facilitate integration of EVOSS products in routine monitoring • To appraise the service, interrogate user feedback and suggest service improvements

  4. User Driven • Observatories • Icelandic Meteorological Office, Iceland • Geological Survey of Uganda • Centre d’Etude et Recherche de Djibouti, Djibouti • Geological Survey of Tanzania, Dodoma, Tanzania • ObservatoireVolcanologique de Goma, Congo • ObservatoireVolcanologique du Karthala, Comoros • Addis Ababa Science Faculty, Ethiopia • Seismic Research Centre, University of the West Indies, Trinidad • Montserrat Volcano Observatory, Montserrat • ObservatoireVolcanologique de la Soufrière de Guadeloupe, FWI • ObservatoireVolcanologique de la Montagne Pelée, Martinique FWI • Observatoire Volcanologique du Piton de la Fournaise, Reunion • InstitutoNacional de Meteorologia e Geofìsica, Cabo Verde • Istituto Nazionale di Geofisica e Vulcanologia, Italy • VAAC • Toulouse Volcanic Ash Advisory Centre, France • London Volcanic Ash Advisory Centre, UK • Other agreements • ESA • EUMETSAT • UNOPS

  5. Theatre of EVOSS Operations • 1 Stromboli (Italy) • 2 Etna (Italy) • 3 Jebel Al Tair (Yemen) • 4 MandaHararo (Ethiopia) • 5 Dalafilla (Ethiopia) • 6 Dabbahu (Ethiopia) • 7 Erta Ale (Ethiopia) • 8 Nyiragongo (Congo) * • 9 Nyamulagira (Congo) * • 10 OlDoinyoLengai (Tanzania) • 11 Karthala (Comoros) * • 12 Piton de la Fournaise (Reunion) * • 13 Soufriere Hills (Montserrat) * • *Hi-Res DEM and Ground Deformation service active • Added after start of the project: • Eyjafjallajökull (Iceland) • Grimsvötn (Iceland) • Nabro (Eritrea) • Mt. Cameroon (Cameroon) • Hierro (Canary) • Jebel Zubair (Yemen) Monitored on a regular basis

  6. EVOSS Services • ATMOSPHERIC SERVICES • Sulphur Dioxide by 4 polar orbiting satellites • Volcanic Ash plumes by geostationary SEVIRI, with an additional Operation-and-Research agreement with EUMETSAT • HIGH-TEMPERATURE ANOMALY SERVICES • Fully automated quantitative exploitation of SEVIRI(15-min repetition rate) and automated off-line use of 2 night-time scenes of MODIS for systematic Cal/Valof results in geometrically diverging zones of the SEVIRI ‘disk’ • Porting of the technique to other platforms/sensors (JAMI onboard MTSAT-2) • GROUND DEFORMATION SERVICES • Integrated exploitation of new, X- band SAR platforms COSMO-SkyMEDover volcanic areas • DEM Development of a processing strategy for high-repetition raterapid mapping, generation of fast, very-high quality, PS constrained Digital Elevation Models

  7. Interaction with end-users • Pre-EVOSS user requirements analysis from ESA Globvolcano project • 2010 First users workshop in La Reunion with potential users worldwide including Mexico, DRC, Italy, Ethiopia (users presented their requirements)... • October 2012 First demonstration of the system to users from Europe and the Caribbean (UK) • January 2013 Second demonstration to users from African region (Ethiopia) • June 2013 Third demonstration to users from Geological Survey of Tanzania

  8. Successful demonstration workshops Charlotte Vye-Brown (BGS) and Kay Smith (BGS) delivered all the demonstration workshops. June 2013 at the Geological Survey of Tanzania

  9. Demonstration • A detailed user handbook was produced containing instructions on using the service and details on the product metadata • At the demonstration, users were able to work through the handbook whilst interacting with the system. • BGS staff provided basic instruction in EO methodologies as well as how to use the system.

  10. Metadata in the handbook

  11. ‘Layer Manipulation’ Layer Selection Metadata Legend Layer Removal Layer Activation

  12. ‘Time Series Analysis’ Detail

  13. Lava flow regime Modelling support Explosive column model

  14. Updates to users A Newsletter was conceived and keeps users up-to-date with progress.

  15. User feedback • Detailed questionnaires were circulated at the demonstration workshops • Response was overwhelmingly positive with assertions that the service MUST continue! • Concerns about practical issues such as bandwidth availability • Hopes for increased resolution and excitement about Sentinels. • Comprehensive User Feedback is available in an EVOSS report

  16. Perspectives Continue to run the system Reinforceoperationalrobustness Extendtheatre of operations (and hence user base) Start to integratephysicalmodelling of the volcanic source with the automatedobserving system
