Magma chamber of magma chambers can be mapped using seismology: seismic waves from earthquakes move more slowly through liquid rock than solid, allowing measurements to pinpoint the regions of slow movement which identify magma chambers. As a volcano erupts, surrounding rock will collapse into the emptying chamber. If the chamber's size is reduced considerably, the resulting depression at the surface can form a caldera. Magma chamber A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is under great pressure, and, given enough time, that pressure can
Negadon: The Monster from Mars creature. His mission accomplished, Narasaki allows himself and "Miroku" to die when Negadon explodes. Negadon: The Monster from Mars In the year 2025, Earth sends an expedition to Mars in the spaceship "Izanami". A huge rock formation is discovered beneath the surface, and is transported back to earth. On the way back, the rock's temperature soars, causing the "Izanami" to explode and crash-land in Tokyo, leaving a large crater. The rock hatches into a colossal alien life form, which proceeds to attack Japan with bolts of energy from its many appendages and orifices. Missiles, tanks, and aircraft all attack but
