Transcript of katla volcano
1775 VEI5: 1.5 cubic km of ejected material
1918 VEI4 OR VEI5: 0.7 cubic km of ejected material
2011 VEI1 ? meanings of katla Katla in Icelandic means ketill ("kettle"), referring to the form of the volcano. Katla is also used as a female first name.
Also "Katla" in Swedish folklore is a female dragon with the ability to spray flames from her mouth just like its namesake volcano, and if a victim of the flames survives, the victim is paralyzed. Katlas Explosive Features For this, the example I will be using is the 934 eruption.
220 million tons of sulfur
ash cloud would cool the earth by 2 degrees
eruption lasted one year
in total it threw about 14 km^3 of ash into the atmosphere Katla's Basic Features Katla's location is in southern Iceland right next door to Eyjafjallajökull. Its nearest plate boundaries are the North American and Eurasian plates. It has three types of magma. The first is basaltic. The reason why the basaltic magma is explosive is when it hits the ice, it creates steam which powers the burst through the ice with an explosive nature. The other two are dacitic and silicic which are usually explosive. The only nonexplosive ones were in 1955, 1999 and 2011
Katla is a sub-glacial volcano which can be a problem because when it explodes it causes something called a jokulhlaups, or glacier-outburst flood.
Katla is not an incredibly tall mountain; it does not have the tall peak that every body associates with volcanoes. It's height is 1512 meters but it has a wide base which is 6 miles in diameter. The crater itself is 10 by 12 kilometers.
About 15 miles away is Vik, Iceland with a population of 350. These people are in the most danger from Katla VEI stands for volcanic explosive index meaning the power of the eruption sources en.wikipedia.org/wiki/Katla_volcano
