An investigation in Hawaii is underway after up to 23 tourists were injured on a lava boat tour off the Big Island.
A flying ‘lava bomb’ crashed into the roof of the boat as it cruised near the Pohoiki lava entry site.
A dozen people were treated at hospital suffering mostly minor injuries and burns but one suffered a broken leg.
Hot lava rocks were hurled out to sea after an explosion, according to the Hawaii County Fire Department.
Passengers said the boat was outside of safety no-go zone designated by the U.S. Coast Guard but DLNR Division of Conservation and Resources Enforcement officers are investigating.
The lava boat captain reported that the boat got as near as 600 feet to the entry point.
The boat, which was seen in images with a huge hole in its roof, is operated by Lava Ocean Tours.
