SummaryThe Geohazards Supersite concept, organized by the Group of Earth Observation (GEO), is intended to facilitate access to space and in-situ data for regional areas exposed to geological threats. The principal objective is to encourage basic research of earthquake, volcano and other hazardous geological processes as a mean of reducing the loss of life from geological disasters. Mt.Etna, a volcano Supersite, features a highly active magmatic/flank fault systems that lie around and beneath an area with a large and dense populous. Complementing any InSAR data are extensive in-situ networks of seismometers and GPS instruments that allow maximization of the scientific interpretation of any InSAR data acquired there. We propose to apply TerraSAR-X repeat pass differential interferometry to study surface change associated with magma transport and other transient fault/flank deformation surrounding Mt.Etna volcano in Sicily, Italy. Previous studies have shown that Mt.Etna volcano and surrounding areas are well-suited for research using InSAR. From June-December 2008 and 2009 Dr. Lundgren tasked TSX data acquisitions for three tracks over Mt.Etna. We will task TerraSAR-X to acquire stripmap data over Mt.Etna from those three tracks plus an additional one, in order to continue observations from multiple look directions. Those data may then be ordered by approved PIs (who have submitted individual proposals via the TerraSAR-XScience Service System) as part of GEO’s Mt. Etna Geohazard Supersite.

Data requirements: Strip-map mode data single polarization (HH). Data amounts: 33 acquisitions per year on each of four tracks covering Mt. Etna, Sicily, Italy.Total data request: 132 scenes per year over the duration of the TSX andTandem-X missions.

Funding in support of the time required to manage tasking and acquisition plans is provided to the PIs by the Italian National Research Council (CNR) to Dr. Sansosti and the U.S.National Aeronautics and Space Administration (NASA) to Dr. Lundgren.
