300,000 square miles
As Krakatoa blew up, it sent something in the magnitude of 5 cubic miles (21 cubic kilometers) of shattered rock into the air.

Is Mount Etna basaltic?
“Mount Etna is a basaltic eruptive volcano” which releases the same type of rock as seen on the Giant’s Causeway in Co Antrim. Basaltic lava does not usually hold much dissolved gas or water so Etna’s flows are slow and regular, similar to those seen in the Hawaiian islands.
