What is an effusive eruption?

An effusive eruption is a volcanic event where lava steadily flows out onto the ground rather than exploding violently. These eruptions are typically characterized by low-viscosity, high-temperature basaltic magmas with low gas content. Hawaiian eruptions are a common example of this style of volcanic activity.

What we know

• An effusive eruption is a type of volcanic eruption in which lava steadily flows out of a volcano onto the ground. [1, 2]
• Hawaiian eruptions are typically effusive eruptions featuring basaltic magmas of low viscosity, low gas content, and high temperature. [4]
• Effusive eruptions produce very small amounts of volcanic ash. [4]
