The eruption of Mount Pinatubo in 1991 was the largest volcanic eruption in 80 years. The explosive eruption deposited tons of ash on the towns and villages near the volcano's base. Even more devastating than the eruption, however, were the devastating flows of water and debris that resulted when monsoon rains mixed with the accumulated volcanic ash. This video segment adapted from NOVA shows the impact of these events on the communities surrounding the volcano.
