Cinders is the substance that is usually not present in explosive volcanic eruptions. Volcanic bombs, pahoehoe or lava and volcanic ash are all present in the explosive volcanic eruptions.
The pahoehoe lava forms from a basaltic rock that is usually dark in color with a smooth or ropey surface it flows slowly as compared to the aa type of lava.
Hence most of the violent volcanic matter can be seen in the Vulcanian, Peléan, Plinian and Phreatic eruption when the ash is supported by pressure from the gases from a strong explosion firm below.
