Is Krakatoa a explosive or non-explosive?
Krakatoa is a volcano that erupted. In the eruption, gases were trapped below the cap of the volcano. The explosive eruption occurred when the pressure was enough to blow the cap off of the volcano.
Was Krakatoa in 1883 more explosive than Mt St Helen's in 1980?
Yes, far more explosive. The eruption of Krakatoa was more than 10 times larger than the 1980 eruption of Mount St Helens.
Did Krakatoa have high viscosity lava?
No, Krakatoa is known for its explosive eruptions due to its low-viscosity lava. This type of magma allows gas bubbles to rise quickly to the surface, resulting in powerful and destructive eruptions.
What eruption type was the Krakatoa eruption in 1883?
The Krakatoa eruption in 1883 was a Plinian eruption, which is a highly explosive volcanic event characterized by the eruption of vast amounts of ash and volcanic material into the atmosphere. The eruption of Krakatoa was one of the most powerful volcanic explosions in recorded history.
How big is Krakatoa's magma chamber?
Krakatoa's magma chamber is estimated to be around 40 cubic kilometers in volume. This large magma chamber plays a significant role in fueling the volcanic activity and explosive eruptions of Krakatoa.
How does the viscosity of magma contrast Krakatoa?
The viscosity of magma affects its ability to flow. For Krakatoa, the magma was characterized by high viscosity due to its high silica content, causing pressure buildup leading to explosive volcanic eruptions. The high viscosity of the magma at Krakatoa contributed to the violent nature of its eruptions in 1883.
Why was the eruption of Krakatoa in 1889 so explosive?
The eruption of Krakatoa in 1883 was so explosive due to the accumulation of high-pressure magma beneath the volcano, which eventually led to a catastrophic release of energy. The eruption was triggered by the collapse of the volcano's magma chamber, resulting in a series of powerful explosions that generated massive tsunamis and global climatic effects.
What was Krakatoa's viscosity?
Krakatoa's magma viscosity was estimated to be relatively low, indicating it was more fluid-like. This low viscosity contributed to the violent explosive eruption in 1883, producing devastating volcanic events such as pyroclastic flows and tsunamis.
How is the Krakatoa classified?
Krakatoa is classified as a volcanic island and part of the Sunda Strait in Indonesia. It is famous for its explosive volcanic eruptions, including the catastrophic 1883 eruption that caused major devastation in the region.
Does Krakatoa have felsic magma or mafic?
Krakatoa volcano typically has mafic magma, which is low in silica content and high in magnesium and iron. This type of magma tends to be more fluid and can lead to explosive eruptions due to the rapid release of gases.
What is Krakatoa a silica rich or a silica poor?
Krakatoa is silica-rich, meaning it contains a high amount of silicon dioxide (silica) in its composition. This high silica content is associated with explosive volcanic eruptions due to the interaction between silica and magma.
What kind of volcano is mt.kraktoa?
Mt. Krakatoa is a stratovolcano, also known as a composite volcano. It is characterized by its steep profile and explosive eruptions due to the presence of viscous magma. The eruption of Krakatoa in 1883 was one of the most powerful volcanic events in recorded history.
