Gormley - The Eruption of Taal

An erupting volcano in Philippines is sitting at alert level 4, the second-highest warning level possible, indicating that a major explosive eruption is possible at any time. While the 331-metre tall Taal volcano's eruption has displaced more than 100,000 people, geologists aren't sure exactly what might happen next at the volatile site. Dr. Tracy Gregg is a volcanologist with the University of Buffalo's geology department, and she says not enough is known about this particular volcano to make an accurate prediction, but there are several geological factors that could indicate an immediate disaster. Gregg, who has also studied the surprising ways that volcanic activity can benefit the environment, joins Gormley to discuss the Taal eruption and why volcanic activity is so unpredictable even with the latest technology.
