Please answer the following question: Question: How long does the volcanic eruption last? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Supervolcano Context: The film begins with a group of hooded people in caribou parkas riding through snow on snowmobiles. Arriving at a nearly buried building, inside they find a video recorded journal of a man who appears to be dying. He tells he is Richard Lieberman, the scientist who was in charge of Yellowstone Volcano Observatory. The film then goes back five years, showing a press conference where Rick and his colleagues are with their boss, Michael Eldridge are trying to persuade the press that their new simulator, VIRGIL, can help determine any possibility of an eruption.

Rick, who is observing the interview, is angered at Ken's words and it is revealed the two are brothers-in-law. The USGS are swarmed with calls, to which all say that the eruption is not imminent. Rick and Ken have an argument about Ken's appearance on TV which Rick passes off as Ken creating a mass panic in order to sell his book, while Ken accuses Rick to holding back when he of all people knows that everything might not be.
