WikiAssignment #1: Cleveland Volcano: Fact # 1: The Cleveland Volcano is a 5,676-foot (1,730-meter) mountain that rises above the remote Aleutian Islands in Alaska. Mount Cleveland is one of Alaska’s most active volcanoes. Its last major eruption was a decade ago, but significant volcanic activity has been observed at the mountain during the past five years.

Fact # 2: Even though its last major eruption was a decade ago, scientists say a growing lava dome in the crater increases the possibility of an explosive event, but does not necessarily indicate that one will occur. It is possible that explosions from the summit crater vent could produce ash clouds that may exceed 20,000 ft above sea level. These events can occur without warning and may go undetected in satellite imagery for hours. If lava dome growth continues, lava may overflow the crater rim to produce a lava flow and/or collapse to produce pyroclastic flows. Sudden collapse of the effusing lava could result in the generation of a volcanic ash cloud. There have been no observations of ash emissions from Cleveland Volcano at this time, but the volcano continues to appear at increased risk for an explosive eruption, according to the Alaska Volcano Observatory (AVO). Fact # 3: Cleveland Volcano is a 5,676-foot (1,730-meter) mountain that rises above the remote Aleutian Islands in Alaska. Mount Cleveland is one of Alaska’s most active volcanoes. Its last major eruption was in 2001, but significant volcanic activity has been observed at the mountain during the past five years. If an explosive eruption were to occur at the Cleveland Volcano it would pose little threat to the nearest residents in Nikolski, a village that is located 50 miles (81 kilometers) east of the volcano. However, a large ash plume could interfere with overflying aircraft.
