Alaskan volcano showing signs it will erupt

Major eruption of the remote Cleveland could disrupt international air travel 

By Yereth Rosen

ANCHORAGE, Alaska — 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 5,676 foot-tall Cleveland Volcano, located on the uninhabited island of Chuginadak in the Aleutian chain about 940 miles 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 20,000 feet above sea level with little further warning, the observatory said.
A major eruption could disrupt international air travel because the 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 more than 5 miles into the sky and spilled lava from the summit crater. Cleveland has experienced several smaller eruptions or suspected eruptions since then.
So far, airlines have not changed their flight patterns because of Cleveland's heat emissions, said Steve McNutt, a University of Alaska Fairbanks scientist who works at the observatory.

Smoking / Steaming Hillside Phenomenon - Southern California - Aug 12, 2011 

南加州的火山附近已經開始有濃煙開始冒出，美國西岸的火山活動正在增加當中。

聖地牙哥也開始出現濃煙，伴隨著令人難以忍受的惡臭。同時美國西岸的地震活動愈來愈頻繁，同時火山活動也有增加的趨勢。

後學在此大膽的猜測，美國西岸和阿拉斯加的火山活動和地震次數，都很有可能會有增加的現象。
