Will Kilauea ever erupt again?

When did Kīlauea first erupt?

about 50,000 to 100,000 years agoFollowing the pattern of Hawaiian volcano formation, Kīlauea started as a submarine volcano, gradually building itself up through underwater eruptions of alkali basalt lava before emerging from the sea with a series of explosive eruptions about 50,000 to 100,000 years ago.
