According to director Roger Donaldson on the DVD commentary the camera Pierce Brosnan uses when he first investigates the volcano surroundings is Brosnan's own.
Pierce Brosnan plays a character with the last name Dalton in this film. Two years earlier he took over the role of James Bond, replacing Timothy Dalton.
The parked school bus that is crushed by the falling church steeple has "Hurd County School District" on the side - a nod to the film's producer, Gale Anne Hurd.
Roger Donaldson had not met Pierce Brosnan before the making of Dante's Peak. He had seen Brosnan play James Bond in GoldenEye, and the two got to know each other before filming of Dante's Peak commenced.
When the volcanic lava begins to destroy the mountain cabin, everyone runs to get onto a small boat. When filming this the first time, the boat sank. Jamie Renee Smith (Lauren) could not swim and Pierce Brosnan held her until a crew member pulled her from the water.
The close-ups of the pyro-clastic cloud erupting were done in a car park with giant gas pumps under a volcano set, which pumped masses of dark-grey cloud 5 or 6 times per second.
