aqmd. The, amount of time that passes between the Pwave arrival and the Swave arrival is. !D,X2:azTG)kPT~Mj 4>d w@O'. By looking at the time between the arrivals of the P- and S-waves, one can determine the distance to the earthquake from that station, with longer time intervals indicating longer distance. The spot where those three circles intersect is the epicenter (Figure 13.12). Use Figure 4.5 and the travel-time graph in Figure 4.4 to determine the distance between each station and THREE SEISMOGRAMS the epicenter. When an earthquake strikes, P waves arrive at a seismograph rst and S waves next. Many updates and improvements! We additionally manage to pay for .

Richter scale Method of earthquake measurement based on the amplitude of seismic . Yw8SxGk}X3kfTfW& gk`41#'uf7"G\fsN4^8jC7[+%`qFLFKpFc (Source: USGS, Wikipedia). The nations most famous fault is the San Andreas Fault, which runs along a north-south trend in southern California, and happens to run directly through Los Angeles. Section 8.1 What Is an Earthquake? Then from the same recordings they determine the earthquake's magnitude, an estimate of the amount of energy released during the earthquake. If you draw a circle on a map around three different seismographs where the radius of each is the distance from that station to the earthquake, the intersection of those three circles is the epicenter. Another method of locating an earthquake is to use the P-wave arrival-time minus origin-time (P - O) interval instead of distance. The distance is in kilometers. If less precision is desired, precede M with a tilde, such as "M ~7" or "magnitude ~6.8.". The longer the time between the arrival of the P-wave and S-wave, the farther away is the epicenter. Since the 1970s, the use of the Richter magnitude scale has largely been replaced in the scientific community by the moment magnitude scale (MMS).
