Yes.High viscosity magmas are thick whereas lower viscosity ones are thin and runny. Therefore higher the viscosity or the resistant to flow property , more violent will be the explosions.
As the magma rises up the mantle the confining pressure reduces which results in the release of potential dissolved gases from the melt.More the dissolved gases more violent will be the explosion.
Yes, high viscosity and dissolved gases in magma can increase the explosivity of a volcano. High viscosity traps gases in the magma, building pressure until it's released explosively during an eruption. Dissolved gases, like water vapor and carbon dioxide, can create a more volatile and explosive eruption when they are suddenly released.

What Tend to increase the explosive potential of magma body beneath a volcano?
high viscosity and dissolved gas
If the magma of a volcano has a high amount of dissolved gas what type of eruption will the volcano have?
Typically, high viscosity, high gas magma results in a Plinian (explosive) eruption. The gas pulverizes the magma into ash and may form lateral pyroclastic flows.
What are the two factors the control whether a volcano eruption will be explosive or quiet?
The two main factors that control whether a volcano eruption will be explosive or quiet are the viscosity of the magma and the presence of dissolved gases. High viscosity magma (thick and sticky) and high gas content tend to result in explosive eruptions, whereas low viscosity magma (thin and runny) and low gas content lead to quiet eruptions.
What is the viscosity of lava flow from a cinder cone volcano?
The viscosity of lava flow from a cinder cone volcano is typically high, leading to slower-moving lava flows. This is due to the higher silica content of the lava, which increases its viscosity. As a result, cinder cone volcanoes often produce short, thick flows that can cool and solidify quickly.
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.

Is pyroclastic material likely to form from low-viscosity or high-viscosity lava?
low viscosity lava due to the violent eruption of the volcano
How viscosity affect volcanic eruptions?
Viscosity is how thick the magma is and this can impact on how much a volcano erupts and how it flows.

What is a caldra?
a crater at the top of a volcano formed by the remains of the last explosions
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
How does erruptions effect the viscosity of an erruptions?
is a erruption a volcano of mt. mayon
The intensity of a volcanic eruption is determined by?
The material inside the volcano.
How does an ash cloud come out of a volcano?
There are two ways a volcano can produce an ash cloud. In most cases gas-rich magma rises inside the volcano. The gas is dissolved in the magma under pressure. As the magma approaches the surface the pressure decreases and the gas is released and expands rapidly, producing an explosion. The magma is blasted apart into tiny particles, which we call ash. The hot gasses then rise, taking much of the ash with them. In other gases, water inside a volcano may come in contact with magma or rocks heated by magma, causing steam explosions. These explosions pulverize some of the rock inside the volcano, during it into ash.
What is the large hole at the top of a volcano called?
The large hole at the top of a volcano is called a "crater." It is formed when explosions or collapses create a depression at the summit of the volcano.
