Hawaii gets disaster warnings about the world's largest active volcano

Hawaii's Big Island residents have been warned that the world's largest active volcano is in a state of heightened unrest, and there's potential for a "lava disaster." It is likely triggered by renewed magma input beneath its summit, accelerating earthquake activity. Residents are being educated on how to prep for an emergency. Mauna Loa has erupted 33 times since 1843 and, most recently, in 1984.
