Seismic sensors placed near Craig for earthquake, tsunami research

The Coast Guard assisted scientists with the U.S. Geological Survey place seismic sensors in waters northwest of Craig to help improve understanding of earthquake and tsunami activity and hazards in Southeast Alaska, according to a Coast Guard release.

Twelve of the ocean-bottom seismometers were placed along a 28-mile section of the Queen Charlotte-Fairweather Fault, according to Coast Guard Petty Officer and spokesman Grant DeVuyst.

“The Queen Charlotte-Fairweather fault is similar to the northern San Andreas fault, with the same earthquake potential,” Dr. Peter Haeussler, a research geologist with the Geological Survey, said in the release. “A problem is that it is located entirely offshore, so it is much harder to study.”

The crew of the Coast Guard Cutter Maple, a buoy tender homeported in Sitka, deployed the sensors over a two-day period on Friday and Saturday since they had the necessary equipment on board to handle hefty equipment.

The sensors and the data they record will be recovered in early June, the release states.
