Another vulcanic eruption, of the vulcano Chaitén in Chile. Lightening in the event of eruptions are often seen. This is believed to be due to ash that rises through the cooler atmosphere, transfer of charge occurs. And this excess of electrons within the cloud act like a capacitor, and with the correct conditions, electrical discharges may be observed as lightning during volcanic eruptions.

Sean Stiegemeier filmed this outstanding video of a volcanic eruption. It was the year 2010 and the Icelandic volcano Eyjafjallajökull halted the European air traffic.


It was a response to the concerns that volcanic ash from the eruptions of Eyjafjallajökull could damage aircraft engines, which led to that the controlled airspace of many European countries was closed to instrument flight rules traffic, resulting in the largest air-traffic shut-down since World War II.
