'''Mount Spurr''' is a [[stratovolcano]] in the [[Aleutian Islands|Aleutian]] Volcanic Arc of [[Alaska]], named after [[United States Geological Survey]] geologist and explorer [[Josiah Edward Spurr]], who led an expedition to the area in [[1898]]. The [[Alaska Volcano Observatory]] currently rates Mount Spurr as [[Level of Concern Color Code]] Green.
There are two vents, the main Mount Spurr summit and nearby Crater Peak. The main Spurr summit has not erupted in over 10,000 years. Crater Peak has erupted twice in historic times; in [[1953]] and again in [[1992]]. Both eruptions led to falls of [[volcanic ash]] in the [[Municipality of Anchorage]] 130 km (81 miles) to the east. As with other Alaskan volcanoes, the proximity of Spurr to major trans-Pacific aviation routes means that an eruption of this volcano can significantly disrupt air travel. Volcanic ash can cause jet engines to fail.
