Philippines: Taal Volcano Eruption

Philippine authorities are warning that a large, dangerous eruption from the Taal volcano may be imminent after a towering column of ash spewed from it Sunday, forcing 30,000 people to evacuate.

Taal is the second-most-active volcano in the Philippines and is one of the smallest in the world. Officials raised the alert level for the volcano to 4 on a scale that goes up to 5. A rating of 4 indicates that a hazardous eruption is imminent
