There isn't really a word to describe the noise a volcano makes when it erupts. You don't just hear it, you feel it.

BOOOOOOOOOOOOOOOM!

A class trip to Borneo starts off with a bang – a visit to a real-life volcano! But when Mount Bako erupts, Sam Fox is left stranded with his teacher, Mr Griffin, who's suffering from a heart attack. They make it down the mountain to the cool blue sea – only to be hemmed in by blood-thirsty sharks . . .
