Is magma a explosive eruption and why?
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.
1883 volcanic eruptions?
It was on the Island of Krakatoa - and the huge eruption blew most of the volcano apart.
How does magma composition and the resulting eruption affect the form of a volcano?
If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
What caused the Eyjafjallokull volcano in Iceland to erupt?
Volcano eruptions are amazing process that don't begin and end in one day. The activity that led to the eruptions actually started at the end of 2009. A first volcanic eruption occurred on March 20, 2010. The eruption that led to the travel disruptions across Europe and beyond occurred on April 14, 2010. After that, there were still more eruptions. A volcano erupts because it sits on top of tectonic plates which move apart, causing the pressure to build up below and eventually erupt.
When was the last eruption of mount terror?
The last known eruption of Mount Terror, which is part of the Ross Island volcanic group in Antarctica, occurred around 1842-1843 during the Ross Island party expedition led by James Clark Ross. There have been no recorded eruptions since then.
What else happened apart from the eruption of Mount Vesuvius?
Jesus happened.

What type of volcanic eruptions occur most often when plates are moving apart?
Most common would be a fissure eruption of basaltic magma.

What is the example of rift eruption?
An example of a rift eruption is the ongoing volcanic activity at the East African Rift, where the continent is splitting apart. This region is known for producing both effusive (lava flows) and explosive eruptions due to the tectonic forces associated with the rifting process.
The world's largest volcanic explosion occurred in 1883 which country when the island of Krakatoa blew itself apart?
False. The island of Krakatoa was indeed destroyed by a massive volcanic eruption in 1883, but it did not plow itself apart, nor was it the largest volcanic eruption. When Krakatoa erupted, it blasted out so much magma, that it left an empty space in the magma chamber. This caused the volcano to collapse in on itself. Such an even is called a caldera forming eruption. The largest eruption of historic times was the 1815 eruption of Mount Tambora. Other, prehistoric eruptions have been much larger.
What type of volcano is the most violent eruption type?
The most violent eruptions are of the "Plinian" type (named for two Greeks involved with the eruption of Mount Vesuvius in 79 AD). In this type of eruption, huge volumes of ash and lava are ejected explosively, often accompanied by horizontal pyroclastic flows of superheated gas and pulverized rock.Generally, eruptions in subduction zones such as the Andes mountains are more violent, where one tectonic plate is being pushed under another, and melted. Areas like these have the most seismic activity as well. Rift zones- where new crust is forming and pushing the plates apart, such as in Iceland, tend to have less explosive eruptions (basalt lava tends to "ooze" out). The most violent eruption was Krakatoa, because it started on the sea bed, where an empty space formed beneath the lava. The sea bed gave way and millions of tonnes of sea water poured into the hot space, with predictable results. the explosion was heard in London, and the shock wave circled the globe several times.

What is an eruption from the side of a volcano called?
An eruption from the side of a volcano is called a lateral eruption. This usually happens at rift zones where a volcano breaks apart. It is also called a flank eruption. If the volcano is explosive, it may also be called a lateral blast.
What happened in the 1350BC Yellowstone eruption?
The 1350 BC was not a super eruption. The last of those in Yellowstone was 640,000 years ago. Instead it was most likely a phreatic eruption, essentially a steam explosion. This type of eruption does not erupt fresh material from magma. Instead water come in contact with magma or superheated rocks underground and flashes to steam, reulting in an explosion. These eruptions can produce clouds of ash as rocks in or on a volcano are blasted apart.
