Dante's Peak (2007)

If Dante's Peak was made 10 years later.

Directed By: Stephen Sommers

Plot
In 1993, USGS volcanologist Dr. Harry Dalton and his partner, Marianne, attempt to escape an eruption in Colombia. She dies when a volcanic bomb lands through the roof of their truck and hits her in the head, leaving Harry devastated.

Four years later, Harry is assigned by his superior, Dr. Paul Dreyfus, to investigate seismic activity near Dante's Peak, Washington, a town that borders a dormant stratovolcano. Harry arrives at the town and meets with the mayor, Rachel Wando, and her children, Graham and Lauren.

Rachel offers to take Harry with them as they see her former mother-in-law, Ruth, who lives near a lake at the base of the volcano. While exploring, they find dead trees, dead squirrels, and even a young couple boiled to death by a hot spring named Twonset, heated up by the volcano's lava. Paul arrives with a USGS team that evening, and they set up base to monitor the volcano. Harry believes the disturbances to be signs of an impending eruption, but Paul disagrees and advises against giving a false alarm. Still, Harry tries to convince Rachel to prepare for a disaster, while developing a relationship with her and the children.

A week passes, but although one of Harry's colleagues, Terry, is injured in an earthquake and avalanche in the summit crater, the volcano shows no signs of serious activity, and the USGS team begins preparing to leave. When Harry goes to say goodbye to Rachel, however, they discover the town's water supply has been contaminated with sulfur dioxide, and the next morning, seismic readings and gas levels rise dramatically. Finally convinced that the volcano will erupt, and with the National Guard unavailable until the next day, Paul gives Harry permission to put the town on alert. Before the group can evacuate the town, the eruption begins. In the ensuing chaos, Harry and Rachel go to retrieve the children, only to find they have gone to get Ruth, who refuses to leave her home. Just as they reach Ruth and the children, a lava flow engulfs Ruth's cabin and destroys the vehicles. The five flee across the lake in a motorboat, but the lake has become acidic due to sulfur-rich gases from the volcano, destroying the motor and eating away at the boat. Ruth jumps out of the boat to help it to shore, but sustains severe chemical burns and eventually dies from her injuries the next morning with her family and Harry at her side.

The heat from the volcano melts the glaciers on the peak, forming a lahar that collapses a dam on the river leading into town. During a lull in the eruption, Harry and the Wandos take a ranger's truck and set off back to town, where the National Guard is helping evacuate the town. A bridge over the lahar fails, and while the USGS team makes it across, their van and Paul are lost to the flood. Meanwhile, Harry and the Wandos are forced to drive across a lava flow in their path, rescuing Ruth's dog, Roughy, along the way. When they arrive back in the deserted town, they find all escape routes gone. While retrieving a distress radiobeacon, Harry learns the volcano is due for a more violent second eruption. As he races for the town's abandoned mine, the volcano explodes, and they barely make it to the mine before the town is overrun and destroyed by pyroclastic flows. The USGS team, watching the eruption from afar, presume Harry dead.

Harry leads the Wandos to Graham's former clubhouse in the mine, only to realize he left the beacon in the truck. When he goes back for it, the mine collapses, nearly crushing the truck and trapping him inside. Harry eventually manages to activate the beacon after much difficulty.

A few days later, Terry notices the beacon has been activated, and the USGS dispatches search and rescue teams. Harry and the Wandos are freed from the mine, reunited with Harry's team, and airlifted out by helicopter. As the credits roll, the camera pans over the obliterated town before turning to the volcano, now reduced to a caldera.
