Etna erupts again.

It seems as though the regions of Iceland and Italy are having a fairly quiet season in terms of volcanoes. Mount Etna, however, erupted on April 10. This is the third eruptive episode of its type to occur in 2011 on the Southeast crater. The type of eruption is strombolian: there was a lava flow, the expulsion of tephra, a gas column and lava fountaining. There were also small pyroclastic flows due to the presence of snow. Though the eruption seemed to have more or less subsided after two days, little is known as to whether more activity will ensue.

This image can be found here. It is an image of a small pyroclastic flow, created as lava passed over snow.
