December and January is the dry season in most of the Phillipines. I guess this area is different for some reason?
Weather in the Philippines is fairly complex. There are 5 climatic zones. On the whole east cost, also in South Luzon, there is no clear-cut dry season with rain falling during most of the year. The heaviest showers are from November till January.
Live links would be great.
It looks like the Philippines' biggest powder keg is on the verge of copying Ontake-san, but luckily with a little more warning than the latter peak:
And an article from yesterday:
Mayon Volcano is an ultra in the Philippines, in the Bicol region which is the southern third of the main island of Luzon. It has an elevation of 8077 ft/ 2462 M. Approximately. I say approximately because that was the official height from many years ago, and several eruptions have altered the summit crater since then.
Mayon is the most active volcano in the Philippines, and the nation's most deadliest. The 1814 eruption killed about 2200 people (http://en.wikipedia.org/wiki/Mayon_Volcano) and 1335 perished in the 1897 eruption (http://en.wikipedia.org/wiki/List_of_volcanic_eruptions_by_death_toll).
Mayon is also the quintessential volcano, the kind you expect in Hollywood movies. It rises up from near sea level to over 8000 teet is an almost perfect cone, as evidenced by its topo contour lines in this image:
and in this photo:
I have in-laws living quite close to Mayon, in Legaspi and San Joaquin, only 7 miles from Mayon's crater and 2 miles from its base. The soil there is understandably rich in nitrogen and the vegetation quite lush. It is near there that I want to retire, but the wife won out and we are preparing to move to her hometown about 75 miles away. I hope to see Mayon's eruption in a couple of weeks (but NOT from very nearby!).
I've had the pleasure of summiting Mayon about 20 years ago, an experience in itself. Both Mayon and nearby Bulusan Volcano have had major eruptions which have altered the summit since I climbed them.
