Deployment of Mount Kupreanof Monitoring Station

AVO recently installed a new temporary monitoring station about 4.5 miles south of Mount Kupreanof that is equipped with seismic, infrasound, and multigas instruments, as well as a pan-tilt-zoom web camera. The station is currently providing seismic data, infrasound data, gas measurements, and web camera images on an intermittent basis. This is by design to conserve battery power, but the frequency of data acquisition can be increased if activity warrants. Web camera images are available on AVO’s website at https://avo.alaska.edu/volcano/kupreanof.

The closest functioning seismometers that provide continuous data are approximately 10 miles (16 km) to the northeast of the volcano as part of the Mount Veniaminof network. Mount Kupreanof is also monitored by satellite data, remote infrasound and lightning networks, and visual observations from pilots and mariners passing by the volcano.

The web camera features a pan-tilt-zoom system that can be remotely operated, allowing for detailed observations of unique points of interest on the volcano.
