The Pu‘u‘Ō‘ō vent in the East Rift Zone of Kīlauea Volcano began erupting on January 3,
1983, and has continued erupting for more than 31 years, with the majority of lava flows advancing to the south.
Another Hawaiian volcanic feature is the formation of active lava lakes, self-maintaining pools of raw lava with a thin crust of semi-cooled rock; there are
currently only 6 such lakes in the world, and the one at Kīlauea's Kupaianaha vent is one of them.
