HONOLULU (AP) — Hawaii’s Mauna Loa, the world’s largest active volcano, began spewing ash and debris from its summit, prompting civil defense officials to warn residents on Monday to prepare in case the eruption causes lava to flow toward communities.

The eruption began late Sunday night in the summit caldera of the volcano on the Big Island following a series of closely spaced, fairly large earthquakes, Ken Hon, the scientist-in-charge at the Hawaiian Volcanos Observatory, said at an early morning news conference. Magma moved to the surface, although lava flows were contained within the summit area and weren't threatening nearby communities.
