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 means of reducing the loss of life from geological disasters. Hawaii, a volcano Supersite, is home to two of the most active volcanoes in the world—Kilauea and Mauna Loa—and is one of the most seismically active places in the United States. We propose to apply TerraSAR-X repeat pass differential interferometry to study surface change associated with volcano, earthquake, and other transient deformation in Hawaii. Previous studies have shown Hawaiian volcanoes to be well-suited for research using InSAR, and initial work by Dr. Lundgren has demonstrated that TerraSAR-X interferograms provide excellent insights into deformation of Kilauea Volcano. From June 2008 through December 2009, he tasked TerraSAR-X to acquire more than 40 data takes on each of two tracks (24 and 32, ~90 total acquisitions). We will build on this work by tasking TerraSAR-X to acquire stripmap data over both Kilauea and Mauna Loa, which may then be ordered by approved PIs (who have submitted individual proposals via the TerraSAR-X Science Service System) as part of GEO’s Hawaii Geohazard Supersite. Data requirements: Strip-map mode data single polarization (HH). Data amounts: 33 acquisitions per year on two tracks covering Kilauea’s summit, Kilauea’s east rift zone, and Mauna Loa’s summit. If possible, a third track would acquire data on the west flank of Mauna Loa, with an additional 33 acquisitions per year. Total data request: 66-99 scenes per year for the duration of the TerraSAR-X and Tandem-X missions. Funding in support of the time required to manage tasking and acquisition plans is provided to the PIs by the U.S. Geological Survey (USGS) to Dr. Poland and the U.S. National Aeronautics and Space Administration (NASA) to Dr. Lundgren.
