AVO Webicorders - Redoubt

AVO uses several different types of data to monitor volcanoes for signs of unrest or eruptive activity. The data displayed here have not been reviewed in any way, and are preliminary unless reviewed by an AVO geoscientist.

Red Lines
RED LINES indicate either a calibration pulse, or where the signal was clipped (too large to be recorded on the scale of the webicorder).

(Station: RDN_EHZ_AV)

Note that due to RDN'S probable burial by snow and ash, the current seismic signal is poor. We expect data spikes and spotty performance from this station until the station is no longer buried. Volcanic seismic activity is not recorded as strongly at RDN as it is at REF. Station RDN is about 4 km (2.5 miles) to the north of Redoubt's summit. A map with the location of RDN and other Redoubt seismic stations is available at http://www.avo.alaska.edu/image.php?id=16308 .
