Monitoring
Mount Augustine is heavily monitored by the Alaska
Volcano Observatory (AVO). The USGS reports that "In
1988, the Alaska Volcano Observatory (AVO)-a cooperative
effort of the U.S. Geological Survey (USGS), the
University of Alaska Fairbanks Geophysical Institute,
and the Alaska Division of Geological and Geophysical
Surveys-was founded to monitor and minimize the effects
of volcanic eruptions in Alaska."8 Upon
the foundation of the AVO, Augustine - the most active
volcano in the Cook Inlet - was the only Alaskan volcano
with a real-time seismic network; since, however the AVO
has instituted similar networks at 26 other Alaskan
volcanoes.8 All of the monitored Alaskan
volcanoes have at least six to eight seismometers
capable of detecting local earthquake activity, with
even more seismometers capable of detecting regional
earthquakes nearby.8 The AVO also analyzes
deformation and gas emission data and daily satellite
images to look for signs of eruptions, namely ash clouds
and thermal anomalies, and makes an effort to create
volcano-hazard assessments by investigating and mapping
the eruptive histories of the monitored volcanoes.8
As of 2001, Augustine has 11 monitoring stations,9
and is monitored by "4 telemetered GPS receivers, 6
telemetered tiltmeters, 10 short-period seismometers and
1 broadband seismometer."10 There
are also a number of webcams and webirecorders that can
viewed by the public at the AVO's website.2
The map below shows the locations of the seismic
monitoring stations located on Augustine Island itself;
according to the USGS report that this map came from,
four other stations, namely AUS, AUC, AUP and AUR, are
not labeled.9
