The viscosity of lava during an effusive eruption is generally low, allowing it to flow easily and spread over large areas. This low viscosity is typically associated with basaltic lava, which has a high temperature and low silica content. As a result, effusive eruptions tend to produce gentle lava flows rather than explosive activity. The fluid nature of the lava contributes to the formation of broad, shield volcanoes.

What types of lava will most likely lead to a volcanic eruption of an effusive nature?
Shield volcanoes have effusive eruptions. Effusive eruptions are a volcanic phenomenon; in some ways the opposite of explosive eruptions. An effusive eruption is characterized by an outpouring of low viscosity lava which has a fairly low volatile content. Usually, shield volcanoes have effusive eruptions.
Will an effusive eruption have more gas and be more dense than an explosive flow or will it be less gaseous and less viscous?
An effusive eruption typically produces less gas and is less viscous than an explosive eruption. Effusive eruptions involve the steady flow of lava, which is usually low in gas content and has a lower viscosity, allowing it to flow easily. In contrast, explosive eruptions are characterized by high gas content and high viscosity, leading to the violent expulsion of magma and ash. Therefore, effusive eruptions are generally less gaseous and less dense compared to explosive ones.
What role did viscosity play on the volcanic eruption?
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.
What factors determine the force of a volcano eruption?
Factors that determine the force of an eruption are magma viscosity and gas content.
What type of eruption does mt santa maria have?
Mount Santa Maria in Guatemala has experienced both effusive and explosive eruptions in its history. The 1902 eruption was explosive, causing catastrophic destruction, while subsequent eruptions have been effusive with lava flows.

What do lava flows made of pahoehoe and AA indicate about the type of volcanic eruption that occured?
They indicate that an eruption is effusive rather than explosive.
