pyroclastic cone

A pyroclastic cone, also known as a cinder cone, is a volcanic landform created by the accumulation of pyroclastic rock fragments, or cinders, around a volcanic vent. These cones typically form steep, conical hills with a bowl-shaped crater at the summit. They develop from explosive eruptions of mafic and intermediate lavas and are often found on the flanks of shield volcanoes. The loose cinders forming the cone are usually inclined at about 30°, the angle of repose. While some cinder cones are small, others can reach heights of several hundred meters, such as Paricutín in Mexico. Despite being made of loose material, cinder cones can be surprisingly enduring because rainwater easily soaks into the permeable cinder, preventing erosion. Pyroclastic cones are among the most common volcano types globally.12
