Giant lava bubble exploding. Etna’s ongoing activity is providing us with some beautiful sights of molten rock coming out from the depths of the Earth, including this amazing photo of a runny basaltic lava bubble exploding. The explosion is hundreds of metres high, being powerful enough to generate a spherical shockwave outlined in lava, and showering the area with glowing bomblets of lava. The volcano has been through a series of powerful paroxysms the last few days. which show no signs of abating. Eruptions are driven by gases exsolving from the magma as it rises and the pressure of the surrounding rocks drops. As it reaches the surface, and effect rather like opening a shaken bottle of champagne occurs. Below we link to a film of the event.
