What are the type of eruptions like at the santorini volcano?
Subglacial eruptions are named because of activity under ice, or under a glacier. They can cause dangerous floods, lahars, and create hyaloclastite and pillow lava. Strombolian eruptions are named because of activity of Stromboli in Sicily. They are characterised by huge clots of molten lava bursting from the summit crater to form luminous arcs through the sky. Collecting on the flanks of the cone, lava clots combine to stream down the slopes in fiery rivulets. The explosions are driven by bursts of gas slugs that rise faster than surrounding magma. Vulcanian eruptions are named after Vulcano, following Giuseppe Mercalli’s observations of its 1888-1890 eruptions. Another example was the eruption of Parícutin in 1947. They are characterised by a dense cloud of ash-laden gas exploding from the crater and rising high above the peak. Steaming ash forms a whitish cloud near the upper level of the cone. In a Peléan eruption or nuée ardente (glowing cloud) eruption, such as occurred on the Ma
