What is pelean lava?
Pelean lava is a type of volcanic lava that is characterized by its highly viscous and thick consistency, which results in the formation of steep-sided lava domes or volcanic plugs. Named after the 1902 eruption of Mount Pelée in Martinique, where this type of lava was prominently observed, Pelean lava typically flows slowly and can build up pressure, leading to explosive eruptions. Its high silica content contributes to its stickiness, making it distinct from other types of lava, such as basaltic lava, which flows more easily.
What volcanic eruption type the most violent?
Pelean
What are the differences between pahoehoe and AA What kind of eruption produces these type of lava?
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.
What kind of lava does Mount Shasta have?
Mount Shasta primarily produces andesitic lava, which is a type of intermediate lava characterized by a medium viscosity and silica content. This type of lava typically results in eruptions that produce a combination of lava flows and explosive eruptions.
What kind of eruption is hot lava?
Hot lava comes from effusive eruptions, where magma is relatively low in silica and flows easily out of the volcano. This type of eruption typically results in slow-moving lava flows that can cover large areas.
What type of eruption does composite volcano have?
The type of eruption that a composite volcano has is lava flow with cinders and bombs in an explosive eruption
How can scientists tell what kind of eruption occurred by studying cooled lava formations?
Scientists can determine the type of eruption by studying features such as the size and shape of the lava flows, the presence of gas bubbles or vesicles, and the composition of the minerals within the cooled lava. Different types of eruptions result in different lava compositions and textures, providing clues to the eruption style and intensity. By analyzing these features, scientists can infer whether the eruption was effusive (gentle, with slow lava flows) or explosive (violent, with ash and pyroclastic flows).
What type of eruption does erebus have?
It's a composite volcano (also known as stratovolcano), which means that it has a big eruption followed by small lava flows. A composite volcano is the deadliest type of volcano and is also the biggest kind.
What is the most violent type of volcanic eruption?
Both the Pelean and Plinian eruptions are violent, and the Plinian (such as Vesuvius) are the most spectacular type. More specifically, there is a designation "ultra-Plinian" to describe highly explosive eruptions such as Kratatoa. The type of eruption that is most violent is when lava, ash and other materials are hurled into the air.
What type of scientists most likely to study the cooling of lava after a volcanic eruption?
A vulcanologist is most likely to study the cooling of lava after a volcanic eruption
What shoots out of a volcano during an eruption?
It depends on the type of eruption. Some will erupt lava or a mixture of lava and gas. Others will erupt gas, ash, and pumice.
What type of eruption causes pahoehoe lava?
High effusion rates
