What is Laki known for?
Laki, volcanic fissure and mountain in southern Iceland, just southwest of Vatna Glacier (Vatnajokull), the island’s largest ice field. Mount Laki was the only conspicuous topographic feature in the path of the developing fissure eruption that is now known as Lakagígar (English: “Laki Craters”).
What happened during the Laki eruption?
The Laki eruption and its aftermath caused a drop in global temperatures, as 120 million tons of sulfur dioxide was spewed into the Northern Hemisphere. This caused crop failures in Europe and may have caused droughts in North Africa and India.
How many deaths did Laki cause?
More than 9.000 people were killed by the direct effects of the eruption, like lava and poisonous gases. The ash was carried away with the wind and poisoned the land and the sea, killing half of the Icelandic cattle population and a quarter of the sheep and horses population.
What caused Laki eruption?
These two events are thought to be related in a single “volcanic-tectonic episode” that fed magma into the Laki fissures and Grímvötn. Like most volcanic eruptions, the Skaftár Fires (as they are known in Iceland) started with a series of earthquakes first noticed 3-4 weeks before the eruption started on June 8.
What type of eruption was Laki?
The Laki eruption lasted eight months during which time about 14 cubic km of basaltic lava and some tephra were erupted.
How did Laki 1783 affect the biosphere?
Away from source, the Laki aerosols were delivered to the surface by subsiding air masses within anticyclones. We show that ∼175 Mt of H2SO4 aerosols were removed as acid precipitation and caused the extreme volcanic pollution (i.e., dry fog) that effected Europe and other regions in 1783.
How long did the Laki eruption last?
eight months
The Laki eruption lasted eight months during which time about 14 cubic km of basaltic lava and some tephra were erupted. Haze from the eruption was reported from Iceland to Syria.
What hazards did Laki 1783 produce?
The Laki eruption belched out huge amounts of gases—including more than 120 million tons of sulfur dioxide—that became caught up in southeast-flowing winds and carried toward Europe. Throughout the summer of 1783, a peculiar “dry fog” was seen in London, Paris, Stockholm, Rome, and beyond.
Did Laki cause the French Revolution?
The Laki eruption was a catalyst for the French Revolution.
How did Laki get its name?
The name Laki comes from Mount Laki, a mountain of volcanic origin that did not actually erupt in 1783, located roughly in the middle of the fissure (Figure 4). In English, the eruption is mainly known as the Laki Fissure eruption.
How was Laki formed?
The Laki volcano is also part of a chain of volcanoes that form from a hotspot. The Laki volcano is a shield volcano, meaning that the volcano is a large, gently sloped volcano made entirely out of lava (volcanoes form when lava or pyroclastic material builds up around a vent).
What kind of eruption was Laki?
basaltic lava
