Document Summary
Earthquakes and faults: movements that produce earthquakes are usually associated with faults. Foreshocks and aftershocks: adjustments that follow a major earthquake often generate smaller earthquakes called aftershocks, small earthquakes, called foreshocks, often precede a major earthquake by days or, in some cases, by as much as several years, foreshocks>major earthquakes>aftershocks. Seismology scale: the study of earthquake waves, seismology, dates back almost 2000 years to the. Push-pull (compress and expand) motion, changing the volume of the intervening material. Generally, in any solid material, p waves travel about 1. 7 times faster than s waves. Move very similar to the way a slinky moves when pushed: secondary (s) waves. Shale motion at right angles to their direction of travel travel only through solids. Move to the side in an up and down fashion. Moves very similar to the way a rope moves when shaken. Measuring the size of earthquakes: two measurements that describe the size of an earthquake are, 1.
