Objective of Geohazard initiative

• Formal Requirement
• task DI-09-01 (Supersites) towards GEO for the
  new 2009-11 GEO workplan
• is to respond to the scientific and operational
  geospatial information needs for the prediction
  and monitoring of geological hazards, namely
  earthquakes, tsunamis, volcanoes and land
  instability.
• Informal Requirement
• Geohazard community stated in workshops, Cat1
  reports,

What is a Super Site?

• stimulating access to data regionally to
  Geohazards Natural Laboratory
• . facilitating access to data over a certain
  number of regional areas. In order to be eligible
  as a Supersite a regional area should meet at
  least one of the following criteria
• populations and elements are exposed to
  geological threats
• an event is expected to occur in the near future,
  or a slow process is already ongoing
• it should be an appropriate place to stimulate
  basic geohazard research (earthquakes hazards,
  landslides, volcanoes, hydro-geological
  processes) and relative sea level rise

Geo hazard Super Site concept
IGOS Geo-hazard executive bureau (long term
existence tbc.)

• Project selection (Cat1)
• Registration
• Compile results
• Make recommendations for new data set

• EOLI- SA catalogues download
• No tasking

• ESA SAR
• Specific archive (SARL0 or/and SLC)
• Fixed data set
• Data regularly added after acquisition
• Standing order to feed specific archive
• No NRT
• Hosted by ESA
• Fixed sites e.g. Izmit, Etna
• Data cost of reproduction paid once
• Searchable catalogue

Currently available ESA Super Sites SAR data

• Super Sites (ESA SAR scenes available)
• ? Hawaii (250)
• ? Etna    (250)
• ? Vesuvius (400)
• ? Los Angeles (100)
• ? North Anatolian fault (20 Istanbul plus east of
  Istanbul)
• ? Tokyo
• Natural Geohazard Laboratory (potential future
  Super Sites)
• Iceland (earthquakes and volcanoes)
• Sakurajima, Miyake-Jima
• East-African rift  earthquakes and volcanoes
• Yellowstone
• Piton de la Fournaise (Reunion)
• San Francisco

? ESA Super Site Archive has mainly been
established with ESA SAR data being provided by
users ? UNAVCO has provided technical support

Geohazard Super Site Trial Example of Cloud
Computing
Trial starts now (once Cat1 has been issued) and
lasts until April 2009

• ? 1 mission across 3 satellites

• Combination of
• EOLI
• Quicklooks at ESA catalogue
• Virtual Archive
• SAR products stored
• Close to the user (Europe, North America, Asia)

Virtual Product ArchiveDownload performance

• 12.20 PM started ? download of several products
  in parallel
• 12.23 / 24 PM? download finished after 4 minutes
  (ESRIN office)

Review gt to make service operational

• End of this year an ESA review on this service
  will take place
• Evaluation of service with following criteria
• user satisfaction
• cost
• GS compatibility
• .....

Summary

• Super Site ESA SAR data are via GeoHazard Cat1
  project easily and fast downloadable using EOLI.
• The Super User Archive has very well been
  initialized based on users have contribution. ESA
  has provided the infrastructure and is the data
  distributor.
• Trial starts now and ends April 2009 ? feedback
  and recommendations are important to evaluate and
  tune the Super Site service.
