This site illustrates the Alaska Volcano Observatory's (AVO) objective to monitor Alaska's volcanoes for the purpose of forecasting volcanic activity and alleviating hazards. AVO's seismometers and satellite imagery allow visitors to obtain current information on selected volcanoes. Because AVO is responsible for volcanic emergencies, people in Alaska can visit the Web site to determine their vulnerability. The site also features AVO's research in geological mapping, modeling of magnetic systems, and development of new instrumentation for predication and interpretation of volcanic unrest. Everyone can appreciate the images of past volcanic eruptions.

| Description | The Internet Scout Report provides evaluation and annotation of high-quality online resources, particularly those that will be of value to the education community. Each resource is selected, researched, and annotated by a team of professional librarians and subject-matter experts, who evaluate sites on the basis of their content, authority, upkeep, presentation, availability, and cost. Published since 1994, the Report is one of the internet's oldest and most respected publications. The Internet Scout Project is part of the College of Letters and Sciences, University of Wisconsin-Madison. |

Last Activity Report ALASKA VOLCANO OBSERVATORY WEEKLY UPDATEFriday, February 3, 2012 11:53 AM (Friday, February 3, 2012 20:53 UTC) CLEVELAND VOLCANO (CAVW #1101-24-) 52°49'20" N 169°56'42" W, Summit Elevation 5676 ft (1730 m) Current Volcano Alert Level: WATCH Current Aviation Color Code: ORANGE Satellite observations throughout the week suggest that eruptive activity at Cleveland Volcano has slowed or paused. Since observation of a new lava dome on 30 January, its size has not changed appreciably. Satellite-derived surface temperatures are consistent with slow to no growth of the dome. There have been no indications of explosive ash-producing activity from distant seismic, pressure or lightning sensors. Renewed eruptive activity producing a small 40 meter (130 foot) lava dome was first observed in satellite data on 30 January 2012, following a month of little to no observable change. The new dome occupies only a small portion of the approximately 200 meter (650 foot) diameter summit crater. There have been no observations of ash emissions or explosive activity during this current lava eruption. The lava dome that formed throughout the fall-winter of 2011 was largely removed by the explosive activity on 25 and 29 December, 2011. It remains possible for intermittent, sudden explosions of blocks and ash to occur at any time, and ash clouds exceeding 20,000 feet above sea level may develop. Such explosions and their associated ash clouds may go undetected in satellite imagery for hours. If a large, explosive, ash-producing event occurs, seismic, infrasound, or volcanic lightning may be detected by local and regional monitoring networks. There is no real-time seismic monitoring network on Mount Cleveland. Additional information on Cleveland Volcano and the current activity may be found at this link: http://www.avo.alaska.edu/activity/Cleveland.php Please see http://www.avo.alaska.edu/color_codes.php for complete definitions of Aviation color codes and Volcano alert levels. Cleveland volcano forms the western half of Chuginadak Island, a remote and uninhabited island in the east central Aleutians. It is located about 75 km (45 mi.) west of the community of Nikolski, and 1500 km (940 mi.) southwest of Anchorage. The volcano's most recent significant eruption began in February, 2001 and it produced 3 explosive events that produced ash clouds as high as 12 km (39,000 ft) above sea level. The 2001 eruption also produced a rubbly lava flow and hot avalanche that reached the sea. OTHER ALASKA VOLCANOES Seismic activity is monitored in real time at 29 volcanoes in Alaska. Satellite images of all Alaskan volcanoes are analyzed daily for evidence of ash plumes and elevated surface temperatures. Some volcanoes may currently display anomalous behavior but are not considered to be at a dangerous level of unrest. Akutan, Aniakchak, Augustine, Dutton, Fisher, Fourpeaked, Gareloi, Great Sitkin, Griggs, Iliamna, Isanotski, Kanaga, Katmai, Mageik, Makushin, Martin, Novarupta, Okmok, Pavlof, Redoubt, Shishaldin, Snowy, Spurr, Tanaga, Trident, Ugashik-Peulik, Ukinrek Maars, Veniaminof, and Westdahl volcanoes are in color code GREEN and volcano alert level Normal. All are at or near normal levels of background seismicity. AVO did not detect ash plumes or significant elevated surface temperatures in the vicinity of any of these volcanoes.
