AVO Webicorders -

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.

UTC Conversion
0000 UTC= 3:00 PM AKST on the previous day as UTC
0600 UTC= 9:00 PM AKST on the previous day as UTC
1200 UTC= 3:00 AM ASKT on the same day as UTC

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).
