Ejecta

When the blockage breaks and cannot sustain itself any longer, a more violent eruption occurs, which allows materials to be ejected out of the volcano.

[3] In planetary geology, the term "ejecta" includes debris ejected during the formation of an impact crater.

[4] Ejecta features are classified based on their distance from the impact crater, the appearance of the ejected material, and the geomorphological characteristics of the terrain.

These patterns are commonly observed on icy surfaces, such as the moons of Jupiter and Saturn, and are indicative of the presence of subsurface volatiles, like water or other ices.

[9] In astrophysics or heliophysics, ejecta refers to material expelled in a stellar explosion as in a supernova or in a coronal mass ejection (CME).
