- http://en.wikipedia.org/wiki/Volcanic_bomb
- A volcanic bomb is a globule of molten rock (tephra) larger than 65 mm (2.5 inches) in diameter, formed when a volcano ejects viscous fragments of lava during an eruption. They cool into solid fragments before they reach the ground. Lava bombs can be thrown many kilometres from an erupting vent, and often acquire aerodynamic shapes during their flight. Bombs can be extremely large; the 1935 eruption of Asama in Japan expelled bombs measuring 5-6 m in diameter up to distances of 600 m from the vent.
