Seismic activity is monitored in real time at 14 volcanoes in Alaska. Some of these volcanoes may currently display anomalous seismicity, but they are not considered to be at a dangerous level of unrest.
Spurr, Redoubt, Iliamna, Augustine, Griggs, Katmai, Novarupta, Trident, Mageik, Martin, Pavlof, Dutton, Akutan, and Makushin volcanoes are all at or near normal levels of background seismicity.
Note: New seismic networks have been installed at Shishaldin and Aniakchak. AVO continues to test these new networks and examine preliminary data to determine background seismicity. Reports on these volcanoes will be added to our weekly update as data acquisition and analysis become reliable. We expect this to occur by mid-November.
