The moment magnitude scale (MMS) was developed in the 1970s as a modification of the Richter scale and is better for measuring big earthquakes but less good for small ones. Some places are more prone to earthquakes than others. The Earthquakes Living Lab gives students the chance to track earthquakes across the planet and examine where, why and how they are occurring.

American Geosciences Institute. Today, most seismologists no longer follow Richter's original methodology because it does not give reliable results when applied to stronger earthquakes and it was not designed to use data from earthquakes recorded at epicentral distances greater than ~600 km.

In Figure 13.9, there is an example seismogram from a station that includes a minor earthquake. If a quake is far from the seismograph, the P-waves arrive long before the S-waves. 2. For example, the western United States has earthquakes more frequently and on a larger scale than the eastern part of the country.

How is the magnitude of an earthquake determined? Another method of locating an earthquake is to use the P-wave arrival-time minus origin-time (P - O) interval instead of distance. Today we will be using a traveltime graph, where the vertical separation between, the P and S curves is equal to the difference in the arrival times between the Pwave, and Swave. Civil engineers, who design houses, apartment buildings, schools, skyscrapers, bridges, highways, tunnels, water treatment facilities, factories and other structures, may use this data to help them create safer structures that are less likely to sustain damage during earthquakes. 107 0 obj
