This Day in Failure: January 14

1993: Thirteen scientists venture inside the caldera of the 14,000-foot Volcán Galeras, historically the most active volcano in Columbia. The scientists take minimal safety equipment, especially odd in light of recent seismographs, which are eerily similar to those recorded just prior to the most recent eruption on July 16, 1992. The volcano erupts while most of the group is on or in the crater, killing six of the scientists and three local hikers.
