A second eruption occurred on the evening of 13 May from a fissure that opened NE of the SE crater, about 800m long. Catania airport had to be closed because of ash emission from Etna. Apart from the emission of lava, the eruption at Etna emitted large amounts of sulphur dioxide (SO2), a colourless and toxic trace gas, into the atmosphere. It plays an important role in climate change if it finds its way to high atmospheric regions through volcanic eruptions, where it can lead to temporary cooling.
