Mount Cleveland had its original eruption back in 1744. The most recent eruption was in March 2013, but it was a small eruption producing ash. Although ash plumes from these eruptions are still a threat to air traffic between North America and Asia. Volcanic ash can damage the exterior of an aircraft as well as be pulled into jet engines where it melts, piles up, and can cause engine failure. Back in May 2001, eruptions on Mount Cleveland sent ash plumes into the air to an elevation of about 30,000 feet in the air which prevented air traffic until the ash plumes
