Types of volcanic eruptions

Lava and other volcanic matter are expelled in many distinctive ways.  These ways were named after the manner in which some well-known volcanoes gave out lava. These are as follow:

volcano fact
Strombolian eruption:
In this eruption, clots of molten lava burst from the vent (summit) into the sky. It looks like fireworks, displaying luminous arcs or fire. It was observed during an eruption of Iruzu volcano in Costa Rica in 1965.

volcano factVulcanian eruption:
This involves the expulsion of ash-laden gas from the peak, forming whitish clouds of ash at the top of the cone. This type was observed in an eruption of Parícutinin 1947.

volcano factVesuvian eruption:
Here, ash-laden gas gushes out violently, forming thick cauli-flower shapes of ash-clouds. It was observed in the eruption of Mount Vesuvius in Italy, in the year 79 A.D

volcano factPeléan / Nuée Ardente eruption:
Here, incandescent lava, together with ash and gas are blown out from the crater, vertically upwards and falling in again. The spilling of glowing avalanches along the slopes can be very deadly and destructive. This type of eruption occurred on the Mayon Volcano in the Philippines in 1968

volcano factHawaiian eruption:
As observed with Mauna Loa Volcano in Hawaii, 1950, this eruption occurs along a fracture (linear vent) with burning lava sprouting from the fracture. It can also occur in a central vent, in which case incandescent lava gushes out in the form of a fountain.

volcano factPhreatic ((say free-a-tic) eruption:
This type does not involve the outpour of lava, but usually set off when cold ground or water comes into contact with hot molten matter. The resulting steam that is forced upwards usually contains débris of surface rocks. No new magma is erupted.

volcano factPlinian eruption:
This eruption type ejects massive viscous lava, with gases and ash, miles into the air. The light nature of the lava is carried miles away by the wind action, and tends to spread many miles from the eruption point.

volcano factDid you know?
In 1815, more than 90,000 people died in Indonesia, from the eruption of Tambora. The eruption sent fiery ash into the stratosphere, cooling the world climate for more than a year
