The opening in the Earth's crust is called a fissure or a vent. These openings can occur as a result of volcanic activity, allowing magma, gases, and other materials to escape from beneath the surface. Fissures can also manifest as cracks or fractures in the crust due to tectonic movements. When they are associated with volcanic eruptions, they can be referred to as volcanic vents.
