Ash and Lightning Above an Icelandic Volcano

Explanation: Why did the recent volcanic eruption in Iceland create so much ash? Although the large ash plume was not unparalleled in its abundance, its location was particularly noticeable because it drifted across such well populated areas. The Eyjafjallajökull volcano in southern Iceland began erupting on March 20, with a second eruption starting under the center of small glacier on April 14. Neither eruption was unusually powerful. The second eruption, however, melted a large amount of glacial ice which then cooled and fragmented lava into gritty glass particles that were carried up with the rising volcanic plume. Pictured above two days ago, lightning bolts illuminate ash pouring out of the Eyjafjallajökull volcano.

Почему в результате последнего извержения вулкана в Исландии вырвалось так много пепла? На самом деле выброс пепла не был уж таким огромным. Вулкан и выбросы, которые он породил, стали такими известными, потому что облако пепла перемещается над густо населенными территориями. Вулкан Эйяфьядлайёкюдль, расположенный на юге Исландии, начал извергаться 20 марта.
