A basketball-sized lava bomb slammed through the roof of a tour boat near an active fissure of Hawaii’s Kilauea volcano early Monday morning, showering the vessel with debris and injuring 23 people, according the Hawaii County Civil Defense Agency.

Officials described the incident on Facebook writing that an explosion off the coast of Kapoho hurled several lava bombs onto the boat — called Hotspot — at about 6 a.m. local time.

“[Four] passengers taken by ambulance to the hospital, one seriously injured with a fractured femur. Most other injuries were superficial,” the post read.
