July 16 (UPI) -- An explosion at the site where lava from Hawaii's Kilauea Volcano meets the ocean left 23 people on a tour boat injured Monday, emergency officials said.
The Hawai'i County Civil Defense said a basketball-sized "lava bomb" punctured the roof of the vessel and scattered debris. Ambulance crews transported four of the more seriously injured passengers to a hospital, including one with a femur fracture.
