2006 UNAVCO Highlights
Title Date
Cascadia Episodic Tremor and Slip Event Cascadia Episodic Tremor and Slip Event The next Cascadia Episodic Tremor and Slip Event is predicted to begin between late October 2006 and late January 2007 (95% confidence limits). A few bursts of tremor lasting three to four days have been reported by the Pacific Northwest Seismic Network and the Pacific Geoscience Centre since November 8, 2006 but the expected event, usually associated with 10 to 20 days of continuous tremor, has not happened yet. Strain anomalies have been noted beginning November 4, 2006 but these could well be caused by the record rainfall which occurred in the area at that time.

Augustine Installation Update Augustine Installation Update AV18 was started and completed in one day (Sunday) just before Karl Feaux and Austin Baldwin arrived at the island on a float plane. On Monday the crews started and completed AV16, a site located on the west island across the lagoon from base camp. Meanwhile, two potential locations for GPS monuments were found during reconnaissance. Excellent weather and clear skies allowed crews to work continuously through both days.

GeoEarthScope Working Group Meetings GeoEarthScope Working Group Meetings All three GeoEarthScope working groups (LiDAR, InSAR and Geochronology) have now met at UNAVCO. These working groups are charged with identifying and prioritizing potential targets for airborne and satellite imagery and geochronology acquisitions through GeoEarthScope. Each group will submit a report to UNAVCO by August 31, 2006. These group reports will be subsequently reviewed and an overall GeoEarthScope acquisition plan based upon the three reports will be presented at open forums during GSA in October and AGU in December.

INSAR InSAR: What it is and why you should care Measurement of changes in the shape of the Earth provides critical insight into a variety of processes of interest to science and society - from subsurface movements of magma, strain before, during and after earthquakes, to motion of ice sheets. Until the late 20th century, measurement of Earth deformation was always time-consuming and frequently perilous because it required the observer to physically touch a point on the Earth's surface with a surveying instrument or establish an expensive observatory.

100th Plate Boundary Observatory GPS Station Installation in Northern California 100th Plate Boundary Observatory GPS Station Installation in Northern California Congratulations to the UNAVCO Richmond, California office for completing the 100th Plate Boundary Observatory GPS station installation in Northern California on June 2, 2006. Short-drilled GPS station P183 was installed on Bodega Head, a spit off of Bodega Bay, California. Bodega Head is one of the few places north of San Francisco where a GPS station can be located on the west side of the San Andreas Fault. Several years ago Bodega Bay was considered as a location for a nuclear power plant. Fortunately, once they discovered the fault line underneath Bodega Bay they decided to look elsewhere.

Data Analysis of the 2005 Olympic Peninsula Semi-Continuous GPS Network Data Analysis of the 2005 Olympic Peninsula Semi-Continuous GPS Network The regular occurrence of episodic deformation transients in Cascadia provides an ideal opportunity to study processes occurring within subduction zones capable of producing great megathrust earthquakes. GPS provides a unique observation of these events, during which the lower part of the subduction interface releases strain without detectable seismic shaking.
