The USGS Earthquake Hazards Program is part of the National Earthquake Hazards Reduction Program (NEHRP), established by Congress in 1977, and the USGS Advanced National Seismic System (ANSS) was established by Congress as a NEHRP facility. The Richter scale was created in the 1930s to assign a single number to quantify the energy released during earthquakes. Point on Earth's surface directly above an earthquake's focus.

The Earthquakes Living Lab gives students the chance to track earthquakes across the planet and examine where, why and how they are occurring. The process is called triangulation. Seismic stations detect earthquakes by the tracings made on seismographs. 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. 4. fault - a fracture in Earth's crust where the rocks on either side have moved. This opens a new window to Michigan Techs UPSeis informational site about earthquakes and seismology. 12), computer or other device with Internet access, journal or writing paper for each student. If the lag time were measured at a location closer to the epicenter, The period of a wave is the time between two adj, How does the period of the P waves compare to t. Use data from seismograms to locate the epicenters of earthquakes. 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. (Figure 3):. The wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium through which it is passing. Focus. For example, the western United States has earthquakes more frequently and on a larger scale than the eastern part of the country.

It's a logarithmic scale from 1 to 10 with each succeeding level representing 10 times as much energy as the last. When the tension becomes too great, the fault slips, causing an earthquake. HS-PS4-1. 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. 5. focus - the point within Earth where an earthquake originates.

In the U.S., earthquake measurements under the MMS (those of magnitude 3.5 or higher) are still commonly erroneously referred to by the general public and media as being on the Richter scale, due to more familiarity with the Richter scale. Finally, the location of the 3 seismographs are placed on a map and the distance to the epicenter is used to draw a circle with an origin at each seismograph and a radius equal to the distance to the epicenter as taken from each seismogram. A circle with a radius of the distance to the quake can be drawn. 1. Answer Key: Lab 5 Earthquakes - Find People EARTHQUAKES: Epicenter Determination and Seismic Waves .
