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. Our successful TerraSAR-X proposal GEO0747 established tasking for the satellite, with 66 planned data takes each year over Hawaii. Here, we propose to use those data for 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 are well suited for analyzing deformation processes 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 continue this work as part of GEO’s Hawaii Geohazard Supersite using stripmap data that have been acquired over both Kilauea and Mauna Loa. 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. Total data request: 66 scenes per year for the duration of the TerraSAR-X mission. Funding in support of the time required to task, analyze, and model the TSX data and causative source processes is provided to the PIs by the U.S. Geological Survey (USGS) to Dr. Poland, the U.S. National Aeronautics and Space Administration (NASA) to Dr. Lundgren, and the U.S. National Science Foundation (NSF) to Dr.Amelung.
