Q:Generate a question that has the following answer: One week for the following movie plot: 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. The man in the video reports that the Yellowstone Caldera eruption has affected nearly everything in the United States, burying much of the country under several feet of volcanic ash.The film then goes back to five years before the incident, where tourists are seen viewing Old Faithful and exploring the hydro volcanic features of the Yellowstone National Park. Inside the visitor's center, the same man from the video journal, Rick Lieberman, a USGS scientist in charge of the Yellowstone Volcano Observatory (YVO), is seen presenting to a crowd on Yellowstone's seismic activity. He states during the presentation, using a fictional holographic projector known as Virgil, that Yellowstone is on the verge of an eruption, as he inputs the current data into the holographic program, a horrific image appears. Instead of the one or two vent idea that the team had envisioned when the volcano explodes, 5 plus vents appear and the holographic program shuts off saying that it is overloaded. They only glimpsed the 5+ vents for a few seconds which leave them significantly unnerved wondering how much truth there really was to what they saw.Later throughout the film, more and more signs of seismic activity occur, all pointing towards the imminent eruption of Yellowstone (such as geyser explosions, earthquakes, Old Faithful going silent, and a mass exodus of wildlife from Yellowstone), though Rick and most of his colleagues try not to cause public panic by saying that these seismic activities do not necessarily indicate an imminent volcanic eruption. However, when Jock Galvin's sarcastic mockery of the situation sparks constant media speculation, it raises public alarm, helped in part by a woman from CNN constantly pressing Rick to confirm the eruption for her reports, and by Rick Lieberman's brother-in-law, who is...
A:
How long does the volcanic eruption last?
