Definitions for "Effusive eruption"
Volcanic eruption where low- viscosity basaltic magma is released. This type of eruption is not explosive and tends to form shield volcanoes.
an eruption characterized by an outpouring of lava onto the ground (as opposed to the fragmentation of lava into the air during violently explosive eruptions)
An eruption dominated by the outpouring of lava onto the ground is often referred to as an effusive eruption (as opposed to the violent fragmentation of magma by explosive eruptions). Lava flows generated by effusive eruptions vary in shape, thickness, length, and width depending on the type of lava erupted, discharge, slope of the ground over which the lava travels, and duration of eruption.
