There are seven types of volcanic eruptions: Strombolian, Vulcanian, Peléan, Hawaiian, Phreatic, Plinian, and subglacial. A Strombolian eruption, named after Stromboli in Sicily, consists of large blobs of magma thrown tens to hundreds of meters in the air, until they fall to the ground and...
The type of volcanic eruption is often labeled with the name of a well-known volcano where characteristic behavior is similar—hence the use of such terms as “Strombolian,”“Vulcanian,”“Vesuvian,”“Pelean,”“Hawaiian,” and others. Some volcanoes may exhibit only one characteristic type of...
Factors Affecting the Type of Eruption The type of volcanic eruption that occurs depends on a number of factors, including the composition of the magma, the depth of the magma chamber, and the presence of water. Magma composition:The composition of the magma, specifically the gas content, is ...
Lava and other volcanic matter are expelled in many distinctive ways. These ways were named after how some well-known volcanoes gave out lava. These are as follows: Strombolian eruption: In this eruption, clots of molten lava burst from the vent (summit) into the sky. It looks like firework...
