Document Summary
Chapter 10, p. 225-245 earth: an introduction to physical geology 4ce earthquakes are neither uniform nor random in their distribution, but tend to be concentrated in long belts that are related to lithospheric plate boundaries. 100-300 km, and deep focus below 300 km, to a practical lower limit of. Based on observations related to the 1906 san francisco earthquake, reid developed a theory, named: the elastic rebound theory; measurements revealed the buildup of strain (deformation) in the region leading up to. Magnitude scale, characterized: a calculation that includes the area of displacement on the rupture, and the shear properties of the rocks. These travel the fastest (1. 6x s waves) and arrive first. These waves characterized: have a compressional form, with energy transmitted through alternating compressions and rarefactions, and particle motion parallel to the direction of wave proagation: secondary (= s = shake) waves. These of course arrive second, after p waves.
