Magma that fuels this type of volcano contains large volumes of gases but not silica and water.

Hi!

This type of volcano is called Cinder Volcano.

Cinder volcanoes are the most simple ones. They have a single vent and the lava ejected from the vent breaks into small fragments that solidify and form a circular cone. The most famous Cinder Volcano is Paricutin, in Mexico, and the most active one is Cerro Negro, in Nicaragua.

Have a nice day!
