WASHINGTON, D.C. -- Alaskan state officials report the Shishaldin Volcano, which erupted on April 19, is being closely monitored. Some flights to the Far East have been rerouted and low flying aircraft are being advised to avoid the area, due to the threat of an additional eruption.

An ash warning has been issued for Unimak Island, where the volcano is located. No lava has been observed, though snow melt and mudflows have been reported and pose a danger to anyone in the area.

Shishaldin is the most active volcano in Alaska and has erupted 27 times since 1775. The most recent eruption was recorded in late 1995 and early 1996. Only low-level steam and ash emissions occurred during the 1995-96 eruption.
