Where and why do earthquakes occur? - ANSWER-Earthquakes occur along plate boundaries and faults due to rocks underground breaking along a fault Are faults the same as plate boundaries? - ANSWER-No; Faults are cracks in rocks/plates, and plate boundaries are where the plates end (Plate boundaries are all faults, but not all faults are plate boundaries - most are not) What are the major types of seismic waves? Which travels fastest? Which causes most damage? - ANSWER-P and S waves. S waves ...

GEOG 1114 Physical Geography - Oklahoma State University. Locating the epicenter of an earthquake using trilateration Now, you will learn how data from seismographs in different locations are used to pinpoint the epicenter of an earthquake via trilateration. The material you need to refer to for this activity is in the file "Epicenter exercise package" on Canvas. The file has the seismograms for three locations (Marlow, OK, Carrier, OK, and Bolivar, MO), a scale with the P-S waves curve, and a...
