Mauna Loa, which means “long mountain” in Hawaiian, erupted at approximately 11:30 p.m. local time on Sunday, this is the eruption of the world’s largest active volcano.

The new eruption, which is the first time Mauna Loa has erupted since 1984, Mauna Loa is one of 15 volcanoes located in the eight main Hawaiian islands. It makes up roughly 51% of the island of Hawaii, according to the U.S. National Park Service. From the bottom of the sea, it stands 30,000 feet — more than 1,000 feet taller than the height of Mount Everest. Much of Mauna Loa is underwater, with only roughly 13,000 feet of it rising above sea level.

As of Monday morning there had been no calls for evacuation. The mayor of Hawaii County, Mitch Roth, said the eruption does not appear to be threatening any downslope communities. But as a precaution, the Hawaii government opened shelters for those who chose to evacuate at the Old Kona Airport in Kailua-Kona and Ka’u gym in Pahala.
