Ash (volcanic) The term 'Ash (volcanic)' as it applies to the area of volcanos can be defined as 'Fragments less than 2 millimeters (about 1/8 inch) in diameter of lava or rock blasted into the air by volcanic explosions. Fragments of lava or rock smaller than 2 millimeters in size that are blasted into the air by volcanic explosions. Fine pyroclastic material in fragments less than 4.0 millimeters in diameter. 'Ash' in this sense is quite distinct from the ash produced by common combustion because the rocks do not catch fire and burn during a volcanic event'.
