An example is like if you taped a block in a box, put a marble inside of the box, and closed the lid. The severity of an earthquake can be expressed in terms of both intensity and magnitude. Near an earthquake the shaking is large and dominated by shear-waves and short-period surface waves. Your email address will not be published. S-waves dont change the volume of the material through which they propagate, they shear it. Seismologists study earthquakes by looking at the damage that was caused and by using seismometers. The radius of each circle equals the known distance to the epicenter. This website uses cookies to improve your experience while you navigate through the website. The oceanic crust of earth is different from the continental part of the earths crust. The movement releases stored-up elastic strain energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake. How do seismometers affect people's lives? What is Earth Science? Answer: Seismic monitoring. . Seismographs detect seismic waves and use this data to study the length and depth of the waves. Unit Test Review.
