Research the eruption of Mount. Cleveland. Describe how the volcano affected the environment and the people near the volcano.

An important danger posed by an eruption at Mount Cleveland is an ash plume that rises high into the atmosphere. In May 2001, eruptions at Mount Cleveland sent ash plumes to an elevation of about 30,000 feet (about 9 kilometers).

Airborne ash can damage the instruments and engines of overflying planes. When an ash eruption occurs, air traffic must be rerouted. This disrupts schedules and significantly increases fuel costs.

Mount Cleveland is an uninhabited island in a remote part of the Aleutian Island arc. The nearest settlement is at Nikolski, about 50 miles (75 kilometers) away. Because this area has historically been poorly monitored, minor eruptions may have gone unnoticed. Because several volcanoes are located close together, there has been difficulty assigning eruptive activity to a specific volcano.

Today eruptions in this area are monitored by the Alaska Volcano Observatory. AVO has daily access to remote-sensing data from a number of satellites. They use this data to monitor for ash in the atmosphere and thermal anomalies on the ground. This data can detect heat produced by lava flows, ash eruptions, and very shallow magma. This type of information was used to detect the eruption on February 19, 2001, which sent plumes of ash to an elevation of 30,000 feet (about 9 kilometers), disrupting air traffic.

A small network of seismographs is needed to detect and map the earthquake activity produced by magma moving beneath a volcano. AVO does not have this type of monitoring on Chuginadak Island. It does have access to earthquake information from the United States Geological Survey's Earthquake Hazards Program, which would detect a very large eruption but not detect minor activity that would produce an ash plume.

Explanation:

they are both the same distance away from the equator and from the poles. both circles are at 66 1/2 degrees. also they both form imaginary line borders of polar regions.

i think it's severe storms but i might be wrong
