When Mt. St. Helens erupted earlier this year, it focused the attention of the whole world on the almost incredible destructive forces that volcanos can release. Geologists from around the world congregated at the volcano and NOVA joined the vigil for an in-depth look at the incident and its aftermath.

NOVA investigates what science can do in helping to solve murder—in understanding why it occurs, and how the rate might be reduced—and explores the work of people who have the stark job of dealing with death: the police, pathologist, scientists and psychiatrists.
