One on the Southern slope,whose lava flows covered the ones from 2001 and the other on the Nothern slope.]]> 2018-04-20 07:29:53 UTC https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/253720844 https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/253738187 This eruption began on 14 December 1991 and ended on 30 March 1993.It was the longest-lasting Etna eruption among the recent ones.The lava flowed out from the system of pits which extended within a few days from 2200 to 3100 meters. It destroyed fruit trees,farms,water systems and villages for exemple Zafferana etnea.]]> 2018-04-20 08:47:24 UTC https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/253738187 wojciech_drewski1 https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/253745848 From april 5 to may 7 different mouths around 3050 from a chasm from which emission of pyroclastic products formed the Sub-terminal cone of the southeast.

Hawaiian eruptions are the calmest types of volcanic events, characterized by the effusive eruption of very fluid basalt-type lavas with low gaseous content. The volume of ejected material from Hawaiian eruptions is less than half of that found in other eruptive types.

Strombolian eruptions are a type of volcanic eruption, named after the volcano Stromboli, which has been erupting continuously for centuries. Strombolian eruptions are driven by the bursting of gas bubbles within the magma. These gas bubbles within the magma accumulate and coalesce into large bubbles, called gas slugs.

20 years ago Etna eruptions were Hawaiian type now is Strombolian .]]> 2018-04-20 09:58:08 UTC https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/253754641 wojciech_drewski1 https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/253756442 This eruption is considered the most devastating in historical times. The eruption  destroyed and buried many inhabited centres reaching up to the sea in correspondence of the western districts of Catania. A series of violent earthquakes destroyed the southeastern flank of the volcano causing damage and collapses. During the eruption an attempt was made to deviate the lava flow.]]> 2018-04-20 10:08:58 UTC https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/253756442 wojciech_drewski1 https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/253758988 The explosion accurred at the front of the lava flow that emerged from a mouth at the base of new southeast crater, at about 3200 meters above sea level. The snow, when it is in contact with the lava, tends to melt, forming pools of water that can be covered by the lava progress. In that case, the water under the lava flow tends to vaporize and can cause fractor-magmatic explosions.]]> 2018-04-20 10:22:09 UTC https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/253758988 wojciech_drewski1 https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/254037993 2018-04-21 09:59:14 UTC https://padlet.com/wojciech_drewski1/o7xyfj00dlx0/wish/254037993
