Evacuations have moved thousands of people to shelters as Mt. Mayon continues to spew ash and lava.

The Philippine volcano has had several minor eruptions over the past several days, and a full-scale eruption is considered imminent.

So far, at least 30,000 people have been displaced in anticipation of an eruption, according to BBC News.

A major eruption would not only be another mark on an already lengthy list of natural disasters for the island nation this year, but would also have impact well beyond the Philippines.

Such an eruption would loft a massive cloud of ash high overhead. Due to the seasonal southward displacement of the jet stream's high-level westerly winds, any such major ash cloud could be drawn into busy cross-Pacific flight paths, which would disrupt international air travel.

The Philippines has already suffered a range of natural disasters this year. Tropical cyclones caused widespread flooding and destructive winds.

At least 10 tropical cyclones affected, directly or indirectly, the Philippines during 2009. Two of these, Typhoon Ketsana (Ondoy) and Typhoon Parma (Pepeng), had severe and destructive weather impacts.
