Icelandic Eruption Menaces Aviation, Again May 27, 2011
Icelandic eruption 2011
Heavier ash falling into the sea, combined with ligher winds than last spring, kept Grimsvotn from disrupting aviation as much as its neighbor Eyjafjallajokull.
Iceland’s Grimsvotn volcano erupted with a massive plume of ash that soared high above the North Atlantic a year after ash from nearby Eyjafjallajokull caused major disruptions to global air travel.

Aviation officials closed airports across Scotland, Norway and other northern European countries after volcanic debris was detected blowing into their air routes.

While the Grimsvotn eruption was far larger than that of its notorious and nearly unpronounceable neighbor in the spring of 2010, its ash was heavier and fell into the ocean at a faster rate.

Ashfall plunged a large area in the southeast of Iceland into nearly total darkness, also covering buildings, cars and farmland with a thick layer of gray soot.

Vulcanologists said Grimsvotn’s blast was the most powerful for 100 years, but the ash plume it created didn’t last very long.

Just like in its eruptions of 1998 and 2004, the volcano ceased spewing ash within a few days.
