Redoubt Volcano, Alaska: Number 9 of America's Ten Most Dangerous Volcanoes

Alaska's Redoubt Volcano, which last erupted in 2009 (pictures), presents a high risk because of its proximity to the city of Anchorage, its international airport, and the flight paths overhead.

Pictured on April 21, 1990, erupting Redoubt Volcano in 1989-90 sparked volcanic mudflows, or lahars, which swept into an inlet some 13.5 miles (35 kilometers) away.

Ash from the volcano temporarily shut down a 747's engines in December 1989. Though the crew restarted the engines in midair, the incident's aftershocks can still be felt in recent on-again, off-again airport shutdowns related to Icelandic volcanic ash. - Source
