A molten “lava bomb” injured 23 people when it crashed onto a Big Island tourist boat on Monday.

Four people were transported to the Hilo Medical Center by ambulance—a 20-year-old woman suffered a broken leg—and others were treated for minor soft tissue burns, says Hawaii’s Department of Land and Natural Resources.
