Summary

The 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.

Our successful TerraSAR-X proposal GEO0891 established tasking for the satellite, with approximately planned 132 data takes per year over Mt. Etna.

We propose to use those data to apply repeat pass differential interferometry and study surface change associated with magma transport and other transient fault/flank deformation surrounding Mt. Etna. 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 continue this work as a part of the GEO’s Mt. Etna Geohazard Supersite using stripmap the data that have been/will be acquired.

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 and Tandem-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 , the U.S.National Aeronautics and Space Administration (NASA) to Dr. Lundgren and the U.S. National Science Foundation (NSF) to Dr.Amelung.
