Book Description
"Seismograms provide the seismologist the most efficient means of 'looking' into the most inaccessible regions of the Earth--the Earth's interior. Geophysical studies based on seismograms have drawn a vivid picture of a planet that has a solid inner core about 1250-km radius, a fluid outer core about 3470-km radius, a mantle about 2900 km thick, and a crust about 30 km thick. Other studies have pinpointed areas of high earthquake risk, where the buildings in which we live and work must be constructed to resist damaging earthquake motion. Further, the methods devised to describe Earth's internal structure have been used by many others to search for rich deposits of oil and minerals beneath its surface and its oceans"--Introduction.
