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
Journey to the Center of the Earth (1959 film) in the form of wedding rings and tooth fillings. Completely exhausted, they reach the opposite shore. While the others are asleep, a hungry Saknussemm catches and eats Gertrud. When Hans finds out, he rushes at the count, but is pulled off by Lindenbrook and McEwan. Reeling back, Saknussemm loosens a column of stones and is buried beneath them. Right behind the collapse, the group comes upon the sunken city of Atlantis. They also find the remains of Arne Saknussemm. The right hand of his skeleton points toward a volcanic chimney; a strong updraft suggests it leads to the surface, but
