There isn't really much information in this report, but Galeras in Colombia has been put on "high alert" for a potential eruption. The volcano did emit a ~2,400 meter steam (and ash?) column today, but beyond this, it is unclear what else might be happening at the volcano.
Galeras is the most active volcano in Colombia, having erupted frequently in the past decade, producing mostly ash falls, ballistic bombs and other explosive volcanic products. It is also located within a few kilometers to Popayán (see photo above of previous activity), a city of ~200,000 people, making it a potentially very hazardous volcano.
