A pyroclastic bomb is a volcanic rock fragment ejected during explosive eruptions. These bombs are molten or semi-molten when they are launched into the air and solidify as they cool down, forming aerodynamic shapes due to the velocity of their launch. They can vary in size from centimeters to meters in diameter and can cause damage or injuries if they land near populated areas.

Does Krakatoa produce lava or pyroclastic flow?
Yes, of course Krakatoa has a pyroclastic flow. Every volcano has an pyroclastic flow, which can travel up to at huge speeds. Krakatoa's pyroclastic flow raced an amazing 200 mph over 20 miles of open sea. Yes Krakatoa has pyroclastic flows but not all volcanoes produce pyroclastic flows, only Mt. St. Helens type volcanoes usually composed of andesite. Kilauea for example does not produce pyroclastic flows because it is composed of basalt, the lava flows out easily.
How are pyroclastic materials classified?
Pyroclastic Material is classified by size from very fine dust and volcanic ash.

Are magma and rock both pyroclastic materials?
