An explosion from a Hawaii volcano sent a ‘lava bomb’ through the roof of a tourist boat, injuring 23 passengers

• Hawaii’s Kilauea volcano is continuing to erupt.
• An explosion sent a lava bomb through the roof of a tourist boat on Monday, injuring 23 people.
• One passenger suffered a broken femur, while the others suffered superficial injuries, according to authorities.

Hawaii officials say an explosion from the Kilauea volcano sent lava flying through the roof of a tour boat off the Big Island, injuring at least 23 people. The state Department of Land and Natural Resources said one passenger broke a leg Monday and others have been burned. According to CNN, the passenger is a female in her 20s and suffered a broken femur.

The other passengers were able to drive themselves to the hospital, and the state fire department told CNN their injuries are superficial. The people were aboard a tour boat that takes visitors to see lava plunging into the ocean. Several companies operate such tours.

A video posted on Twitter by Hawaii News Now reporter Mileka Lincoln reportedly shows the explosion that sent the lava bombs flying:

Officials have warned of the danger of getting close to lava entering the ocean, saying the interaction can create clouds of acid and fine glass.

The volcano, which has been slowly and continuously erupting for decades, entered a new, more violent eruption phase in May.

Thousands of residents were forced to evacuate following a series of eruptions, and hundreds of homes, offices, and other structures have been damaged around the Big Island.

Officials are interviewing injured passengers at a hospital.
