The viscosity of magma or lava will determine whether or not the eruption is explosive or quiet. Higher viscosity magma can result in explosive eruptions. Lower viscosity magmas tend to flow more freely.
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.
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.
The size of the magma chamber and the viscosity of the magma.
The explosiveness of an eruption is primarily controlled by the viscosity of the magma and the amount of gas trapped in it. Low viscosity magma with high gas content tends to lead to more explosive eruptions, while high viscosity magma with lower gas content leads to less explosive eruptions.
Viscosity of magma affects the explosivity of a volcanic eruption. High-viscosity magma tends to trap gas bubbles, leading to pressure build-up and explosive eruptions, while low-viscosity magma allows gas to escape more easily, resulting in effusive eruptions. Ultimately, the viscosity of magma influences the type and intensity of volcanic activity.
Viscosity is how thick the magma is and this can impact on how much a volcano erupts and how it flows.
The main cause of differences in volcanic eruption characteristics is due to the viscosity of the magma. High viscosity magmas are high in sticky silica which traps gas and produces explosive eruptions. Low viscosity magmas are low in silica and produce eruptions with far less energetic characteristics.

They feature magma with very low viscosity
The size of the magma chamber and the viscosity of the magma.
The viscosity of andesitic lava affects its flow behavior during volcanic eruptions. Higher viscosity lava flows more slowly and tends to form thicker, blockier lava flows, while lower viscosity lava flows more easily and can travel further before solidifying. This relationship influences the type and intensity of volcanic eruptions.
Low viscosity mafic magma.
Mount Fuji's magma is known to have relatively low viscosity compared to other volcanoes, which contributes to its more gentle eruptions. This low viscosity magma allows for gases to escape more easily, reducing the likelihood of explosive eruptions.
