Early Monday morning, 23 passengers on a lava tour boat were injured when an explosion at the ocean entry
hurled lava bombs and debris onto their boat. Of the injured, 4 were taken by ambulance, one seriously injured with a fractured femur. Most of the injured passengers had superficial injuries and were treated on arrival at Wailoa Harbor in Hilo.
A basketball-sized lava bomb punctured the vessel's roof, and explosion debris littered the floor of the boat.
