Hawaiian Volcano Observatory

The world’s most active volcano started erupting once again on Thursday. Kīlauea is showing signs that magma is moving towards the surface of Halemaʻumaʻu crater. The Hawaiian Volcano Observatory assembled field crews to respond. Geologist Drew Downs is part of the team.

Kīlauea volcano began erupting inside its summit crater on Thursday. The eruption comes less than one month after Kīlauea and its larger neighbor Maunaloa stopped releasing lava.

Maunaloa’s first eruption in almost four decades is over. And nearby Kīlauea has also gone quiet. Geologist Matt Patrick said that while the volcanoes have distinct magma systems, it is possible they affected one another. HPR's Savannah Harriman-Pote has more.

The U.S. Geological Survey’s Hawaiian Volcano Observatory said in a statement Tuesday that Kīlauea is no longer erupting. The agency followed with a separate statement declaring Maunaloa is no longer erupting.

Scientists say lava from Maunaloa is no longer an imminent threat to the main highway across the Big Island. The U.S. Geological Survey said Thursday that the volcano is still erupting, but lava that was feeding the flow heading toward the road has been cut off.

The ground is shaking and swelling at Maunaloa, indicating that it could erupt. Scientists say they don’t expect that to happen right away but officials on the Big Island are telling residents to be prepared in case it does erupt soon.

Research geologist Frank Trusdell from the Hawaiian Volcano Observatory spoke with The Conversation's Savannah Harriman-Pote about what an eruption of Maunaloa might mean for Hawaiʻi Island residents. He says we are looking at a "reawakening" of the world's largest active volcano.
