A dash to the beach in between heavy showers came upon a scene like a volcanic eruption because of all the pumice visible . Fallout from Krakatoa ? For example , the surface of Alma Creek , above , on Magnetic Island , was covered with a sheet of pumice with coconuts bobbing about near the weir , just before the stream discharges into the sea .
In turn the beach had a large amount of pumice spread along its entire length . A combination of king tides and heavy rain is responsible for the build up .
Pumice has been washing up on the island for years and hearsay has it that it came from an eruption in the Solomon Islands .
