A sightseeing trip almost ended in disaster when huge lava bombs came crashing down around a tourist boat.
Thrill seeker Matthew Davison, 34, captured the sudden eruption from the Anak Krakatau volcano near Jakarta, Indonesia, from the boat.
Mr Davison, who is from Auckland, New Zealand, said "car-sized" pieces of molten rock came hurting down the volcano and splashed into the water around him, according to the Daily Mail.
In the dramatic footage filmed on Tuesday, glowing rocks can be seen flying through the air, surrounded by smoke and people can be heard shouting.
