Petra, that movie was Dante's Peak. I saw it, and liked it. I think geologists liked it, but reviewers did not. It was very realistic except 2 things....a lake that went instantly acid to the point of melting a boat, and a Hawaian-style lava flow that they drove across. I guess Pacific northwest volcanos can have lava flows, even basaltic ones, but probably not in the middle of a silicic (sticky) eruption. The most realistic part was the pyroclastic flow...realistic to the point of me wondering how it was made. Speaking of acid lakes and pyroclastic flows, the best thing I've ever seen on volcanos is the show "Nature", called the "Volcano Watchers", about the Krafts of France. The went out on an acid crater lake in their department store rubber raft to sample the waters. There was liquid sulfer oozing into the lake. They lowered their water sampling bottle on a steel cable, and the deeper they went, the more acid it was...until it ate right through their steel cable. In the movie, Maurice (?) stated that they took chances because they had lived good lives, and being taken by a volcano would not be that bad (or something to that effect). Unfortunately, they took 40 others with them, killed by a pyroclastic flow at Mount Unzen in 1992, in Japan. We knew one of them---Harry Glicken, of UCSB. Harry was supposed to have been on Mount Saint Helens on the day she blew. The person who replaced him for the day was killed. When you enter the geology building at UCSB there is a plaque on the left in memory of Harry....Chris
