What type of magma does mount Pinatubo have?
Mount Pinatubo primarily erupts dacitic magma.
Does Pinatubo have silicia?
The magma of all volcanoes contains silica. The 1991 eruption of Mount Pinatubo involved dacite magma, which has a high silica composition.
Where did the magma come out when mount Pinatubo exploded?
It was release through a number of vents, first from near the summit and later from along its flanks.
What best describes the composition of the magma that erupts at Mount Pinatubo in the Phillippines?
The magma that erupts at Mount Pinatubo is mainly dacitic in composition, which is a type of intermediate magma that is rich in silica. This type of magma typically leads to explosive eruptions due to its high viscosity and gas content.
How did mount pinatubo occur?
Mount Pinatubo and the surrounding volcanoes of the volcanic arc rise up because of magma occlusion from the subduction plate boundary.
What type of eruptions does Mt Pinatubo have and what causes the eruption to be violent or non-violent?
Mt. Pinatubo is known to have explosive eruptions. The violence of an eruption is influenced by the amount of dissolved gas in the magma, the viscosity of the magma, and the presence of water or other fluids. If the magma has high gas content, is highly viscous, and interacts with water, it can lead to a more violent eruption.
Mount Pinatubo in Philippines is what type of volcano?
Mount Pinatubo is a stratovolcano, which is characterized by having a tall, conical shape with steep sides. Stratovolcanoes like Pinatubo typically have explosive eruptions and are associated with magma that is high in silica content, resulting in thick and viscous lava flows.
What type of igneous rocks are from mt Pinatubo?
The igneous rocks from Mt. Pinatubo are primarily dacite and andesite. These rocks form as a result of magma being pushed up towards the surface and cooling relatively quickly, creating a mix of intermediate composition rocks.
What type of eruption will Mount Pinatubo produce?
Mount Pinatubo is known to produce explosive eruptions due to its composition of magma. These eruptions can result in a large ash cloud, pyroclastic flows, and even lahars which are fast-moving mudflows.
How much CO2 did Mount Pinatubo release?
The 1991 eruption of Mount Pinatubo released an estimated 20 million tons of sulfur dioxide into the atmosphere, leading to a cooling effect on Earth's climate. The volcano did not release a significant amount of carbon dioxide.
How did the mount Pinatubo plates move?
The plates involved in Mt. Pinatubo's eruption are called a destructive plate boundary. This means that the plates move towards each other and the oceanic plate is denser than the continental plate and therefore it moves underneath the continental plate. As this peice of land moves underneath this is called the subduction zone, and the plate moves into the magma chamber of the volcano and it melts as magma which forces the magma up the main vent thus causing an eruption.
What type of eruption did mount Pinatubo have?
Mount Pinatubo had LATERAL eruption. It means, generally volcano erupts at its highest peak where its vent finds an opening, but mount Pinatubo got a weak side and therefore it erupted laterally.
