The eruption of Hawaii’s Kīlauea volcano has displaced Big Island residents, sent molten rock hurtling into a sightseeing boat and spewed enough lava to create a whole new peninsula.

And it’s only just started, relative to the time it could go on for, said a U.S. Geological Survey (USGS) report released on Friday.

The event could last months, or even go on for a year or two if it maintains a high eruption rate, the report said.

The eruption can be traced back to April 30, when the Puʻu ʻŌʻō vent in the middle East Rift Zone of the Kīlauea volcano started collapsing.
