Lava extrusion refers to the process by which molten rock (lava) is expelled from a volcano during an eruption, typically forming various geological features like lava flows, lava domes, or cryptodomes. This process is crucial in shaping the landscape and can significantly influence volcanic hazards and landforms. The characteristics of the lava, including its viscosity and temperature, determine the style and extent of the extrusion, affecting both the eruption's dynamics and the resultant formations.
