Lightning during a volcanic eruption
• Lightning during a volcanic eruption
"Dirty thunderstorm" - this is an extremely rare natural phenomenon, which is sometimes accompanied by large volcanic eruptions. The term "dirty thunderstorm" refers to lightning occurring in the cloud, which rises from the crater of a volcano during an eruption.

Generally, dirty thunderstorm observed only during the eruptions of several volcanoes. This is a rare phenomenon.

Transfer to Japan. Thunder and lightning. The eruption of the active stratovolcano Sakurajima, located on the peninsula of the island of Kyushu Osumi in the Japanese prefecture of Kagoshima, February 5, 2016. The height of the volcano - 1117 meters, and the area - about 77 square kilometers. At Sakurajima has three peaks.
Generally, this phenomenon - "dirty thunderstorm", regularly observed during the eruption of the volcano Sakurajima in Japan, one of the most active volcanoes in the world.
Dirty thunderstorms are common phenomenon and observed since ancient times, in particular, the first confirmed case of lightning occurred during the eruption of Vesuvius in 79 BC. e., and since the 1940s there they began to capture on photographic film.

In the spring of 2010 in Iceland began erupting volcano. The atmosphere was ejected huge ash cloud, whereby most of the airspace continent turned closed, and a plurality of flights was reversed. Photos of the grand event in large numbers went to the Internet, and the name of the volcano - Eyjafjallajokull (in translation - "island mountain glacier").

It is incumbent Sinmoe stratovolcano, one of the cones head volcano Kirishima-pit at the junction of the prefectures of Miyazaki and Kagoshima. During its eruption in 2011 was a "dirty thunderstorm."
Another famous center of "dirty thunderstorm" is located in Chile. This eruption of the Chilean volcano Puyehue in 2011. Puyehue is located in the eponymous national park and is part of a volcanic chain that bears the name of the Puyehue-Cordon Kaulle.
Puyehue volcano 2240 meters is located on the Chilean side of the Andes.

Lightning is formed by the collision of large electrical potential, which is negatively charged by falling ash particles and positively charged thickened volcanic gases in the column of ash rising plume into the air during a volcanic eruption. Puyehue-Cordon Kaulle in Chile, in 2011.
