GeoEarthScope, a part of the EarthScope Program, includes the acquisition of aerial and satellite imagery and geochronology to examine the strain field beyond the decade time scales available from the PBO geodetic instrumentation. A goal of EarthScope is the improved understanding of the tectonic evolution of the North American continent. Identifying and understanding deformation rates in all tectonic regimes is critical to reaching that goal. UNAVCO provides support for EarthScope related imaging and geochronology activities.
GeoEarthScope MREFC activities concluded successfully on September 30, 2008. An overall summary of accomplishments is as follows:
AIBORNE LIDAR IMAGERY. Data acquisition campaigns took place in 2007 and 2008 and cover a total area of nearly 5,000 km2. General maps of GeoES LiDAR coverage are available here. Google Earth files showing detailed coverage by target region are available here. All NoCal data are processed and available as Google Earth hill-shade files or ARC binary DEM files from www.opentopography.org. Data from other regions are currently being processed and will become available soon.
SATELLITE INSAR IMAGERY. Synthetic aperture radar (SAR) data suitable for interferometric analyses were ordered from data provider catalogs, spanning the period from 1992-2008 and covering all of the western U.S. as well as parts of Alaska, Hawaii, and regions in the eastern and southern U.S. The GeoES catalog currently contains ~16 TB of SAR data with several more TB's expected to be delivered soon. More details, including data access procedures, are available at http://geoes-insar.unavco.org/main.php.
GEOCHRONOLOGY. Twelve geochronology laboratories received GeoES funds in 2007 to provide geochronology services to investigators independently identified and supported by NSF via the standard proposal process. For the list of supported labs and available services please refer to the following FAQ.
Details and final reports regarding the above MREFC activities will be added to this site during the coming months.

We are pleased to announce the availability of new EarthScope airborne LiDAR data products from Southern California and the Intermountain Seismic Belt (ISB):
Like the rest of the GeoEarthScope LiDAR dataset, these products are freely available from the OpenTopography portal at http://opentopography.org in the following formats:
We are pleased to announce the availability of new GeoEarthScope airborne LiDAR data products from the Intermountain Seismic Belt (ISB) project! This release includes high resolution LiDAR topography data collected in tectonically active regions of Utah and Wyoming, including Yellowstone and Grand Teton National Parks and the Nephi segment (southern strand) of the Wastach fault. These LiDAR data can be explored and downloaded in several ways:
Additional ISB LiDAR data products will become available in the coming months, including coverage of the northern strand of the Nephi Segment of the Wasatch Fault, as well as point cloud access and custom DEM generation capability for all ISB coverage using GEON developed cyberinfrastructure. A metadata document for this project is also currently in preparation.
We would like to thank the National Park Service, with special thanks to the Geology, GIS and fire cache personnel at Yellowstone and Grand Teton national parks, for their support and collaboration.
