RECENT satellite images of a remote Alaska volcano along a flight route for major airlines show it may be poised for its first big eruption in 10 years, scientists said.
The Alaska Volcano Observatory has issued an eruption advisory for the 1,730-meter tall Cleveland Volcano, located on the uninhabited island of Chuginadak in the Aleutian chain about 1,500 kilometers southwest of Anchorage.
The advisory was based on "thermal anomalies" detected by satellite, the observatory said on Thursday. Those measurements indicate the volcano could erupt at any moment, spewing ash clouds up to 6km above sea level with little further warning.
A major eruption could disrupt international air travel because Cleveland Volcano, like others in the Aleutians, lies directly below the commercial airline flight path between North America and Asia, said John Power, scientist-in-charge at the Alaska Volcano Observatory.
The volcano's last major eruption came in 2001, when it blasted ash over 8km into the sky and spilled lava from the summit crater. Cleveland has experienced several smaller eruptions or suspected eruptions since then. Scientists are not always certain about what is happening at the remote volcano, officials said.
