PEANUT BUTTER CLUB: Presents the video “The Next Pompeii” on Friday, September 20, at noon, in Redfield Auditorium, 45 Water St., Woods Hole. In the shadow of Italy’s Vesuvius, a lesser-known volcano rumbles: Campi Flegrei. If it erupts, millions of lives could be at risk. Scientists explore its unique geology and develop a warning system that could prevent Naples becoming the next Pompeii. Sponsored by the WHOI Visitor Center. Coffee, tea, and cookies served. Donations accepted.
