Officials in southern Colombia have issued a code orange alert for the newly-active Galeras volcano which they said could erupt in a matter of days or weeks, according to the state-run Geological and Mining Institute.
Galeras (Urcunina among the 16th-century indigenous people) is an Andean stratovolcano in the Colombian department of Nariño, near the departmental capital Pasto. Its summit rises 4,276 metres (14,029 ft) above sea level. It has erupted frequently since the Spanish conquest, with its first historical eruption being recorded on December 7, 1580. A 1993 eruption killed nine people, including six scientists who had descended into the volcano's crater to sample gases.It is currently the most active volcano in Colombia.
Authorities said they are continuing to monitor the nearby Authorities said they are continuing to monitor the nearby Huila volcano, also on orange alert, where sizeable volcanic activity also has been detected in recent weeks.volcano, also on orange alert, where sizeable volcanic activity also has been detected in recent weeks.
Nevado del Huila (in English (IPA) /nɛˈvɑː.do dɛl ˈwi:.la/), at 5,365 metres (17,602 ft), is the highest volcano in Colombia, located in Huila Department. After being dormant for more than 500 years, the volcano showed heavy signs of activity in 2007 and 2008. As of February 20, 2007, there were more than 7000 "minor" seismic events, and a high state of alert was in place for the departments of Cauca, Huila, Caldas and Valle del Cauca. The volcano erupted twice in April 2007, once in April 2008 and again in November 2008. Any eruption would affect the small villages around the volcano, mostly Paez, Cauca, where their habitants still have in memory the eruption of the Nevado del Ruiz volcano and the destruction of Armero.

An easier resource to see the activity is at RSOE EDIS.

Seems all the world's volcanoes are quite active now.

A good job Chaiten isnt on the list (yet) with its LavaDome still capped at the peak, any future eruption here would be cataclysmic on about the Same Scale as Montserrat..if not larger.
The 2 Volcanoes on watch now are as a result of magma movement below S.America convectionally rising through the Convergent zone, The Earthquakes in the past 2 months have weakened the faults in the crust making movement of this Magma easier to the surface and thus any eruption would be more lava-type around the Caldera than Pyroclastic as a result of the gases being "stored" for any duration of time.

Would it have anything to do with the sun's solar cycles or sunspot activity? Maybe they are related on some level.
