(Station: RSO_EHZ_AV)

October 4, 2011: The signals from station RSO is currently troubled with radio interference from an unknown source. Station RSO is located 3 km (2 miles) south of the Redoubt summit and can be very sensitive to activity at the summit. A map showing the location of RSO and other Redoubt seismic stations is available at http://www.avo.alaska.edu/image.php?id=16308.
