A crack in the Earth's crust where volcanic material escapes is known as a fissure. Fissures can occur during volcanic eruptions, allowing magma, gases, and ash to flow out from the Earth's interior to the surface. These openings can vary in size and length, and they often serve as pathways for lava to reach the surface during volcanic activity. Fissures can also contribute to the formation of features such as lava plateaus and rift valleys.
