The smoky cloud that rises from the vent of an actively erupting volcano is composed of fine volcaniclastic debris (ash) suspended in the air. This is because when a volcano erupts, it ejects ash, rock fragments, and gases into the air which combine to form a cloud-like plume. The ash is usually made up of pulverized volcanic rock, and it can be carried by wind to distant areas.
