Alaska Volcano Observatory
AVO Webicorders - Semisopochnoi
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.
0000 UTC= 4:00 PM AKDT on the previous day as UTC
0600 UTC = 10:00 PM AKDT on the previous day as UTC
1200 UTC= 4:00 AM AKDT on the same day as UTC
1800 UTC = 10:00 AM AKDT on the same day as UTC
RED LINES indicate either a calibration pulse, or where the signal was clipped
(too large to be recorded on the scale of the webicorder).
Semisopochnoi 24 hour webicorder
CERA is 6.4 km (4.0 miles) east-southeast of Cerberus on Semisopochnoi Island. Data from this network will likely be intermittent until somebody can get there this summer.
