Effusive eruptions occur when magma rises to the surface and flows out of a volcano rather than exploding violently. This type of eruption typically produces lava flows that can travel long distances, creating broad, gently sloping landforms known as shield volcanoes. The lava is usually low in viscosity, allowing it to spread easily. These eruptions are often associated with basaltic magma, which has a lower gas content compared to more explosive magma types. As a result, effusive eruptions tend to be less hazardous to nearby communities, although fast-moving lava flows can still pose risks to infrastructure and natural landscapes.
