Hawaii officials are warning residents of the Big Island that Mauna Loa, the world’s largest active volcano, is sending signals that it may erupt. Scientist say an eruption isn’t imminent, but they are on alert because of a recent spike in earthquakes at the summit of the volcano. Experts say it would take just a few hours for lava to reach homes closest to vents on the volcano, which last erupted in 1984. The volcano makes up 51% of the Hawaii Island landmass, so a large portion of the island has the potential to be affected by an eruption.
