Storm clouds in Iceland in 2016, which produced a tornado

Tornadoes in the country of Iceland are extremely rare, with only 13 events ever being recorded in the country's history. No fatalities or injuries have ever been recorded because of tornadoes in Iceland, and the highest rated tornado to ever occur was an F1.

Climatology

[edit]

Thunderstorms are extremely rare for any specific location in Iceland, with fewer than five storms per year in the southern part of the island. They are most common in early or late summer. They can be caused by warm air masses coming up from Europe, or deep lows from the southwest in wintertime. Lightning can usually be observed in connection with ash plumes erupting from the island's volcanoes. Vortices, sometimes on the scale of tornadoes, also occur with volcanic eruptions. Landspouts and waterspouts are occasionally observed. Classic mesocyclone derived tornadoes (i.e. forming from supercells) are very rare, but have been observed. Any of these do occasionally cause damage, although the sparse population further reduces the probability of detection and the hazard.[1][2]

Lava tornadoes of September 3-13, 2014

[edit]

From the days of September 3 to September 13 of 2014, a volcanic eruption and subsequent lava field spawned multiple lava and fire tornadoes, an extremely rare phenomena in which smoke from a fire[11] (most commonly from wildfires, but can also be found in other events) mixes with cold atmosphere, creating an extremely hot rotating cloud of smoke which can ignite objects it tracks through.[12]

On September 3, a cloud of sulfur dioxide gas originating from the Holuhraun lava flow caused the formation of a fire whirl, which consisted of a column stretching 3,300 feet (about 1 kilometer) into the air. A remotely monitored infrared camera caught the event on video. Multiple other "lava tornadoes" touched down in the days following, many of which were brief and only touched the ground for 5–10 seconds.[13]
