It reaches its greatest height in shallow water. NOTE: Out of stock; self-printing only. In order to locate the epicenter of an earthquake, you need to estimate the time interval between the arrival of the P and S waves (the S-P interval) on the seismograms from at least three different stations. Intro to Travel Time Graphs. After determining the S-P interval, use the S-P graph to get the . The distance of the epicenter from the seismic station is equals to 127 km(minimum). Using the data obtained from the seismic station, seismologists can read the lag time of 16.9 seconds of P waves before S waves detected. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. An earthquake of magnitude ML 2.5 it took place this morning not far from Rome. The earthquake happened at a place where there is no fault, so the epicenter is not near a fault line. In Figure 13.9, there is an example seismogram from a station that includes a minor earthquake. We have a new and improved read on this topic. Tsunami. P waves are compression waves and travel faster through the Earth than S … The epicenter of the earthquake is somewhere on the edge of that circle. For part 3) To locate the epicenter of an earthquake, three seismograms are needed. The cities Kodiak and Anchorage are shown on the map. The point within the earth where the actual movement takes place is called the focus. Agree with Dr. Booden's answer, except for the part about the epicenter being the location of the greatest vibration. The focus is the point beneath the surface where the earthquake occurs. How long did it take the P-wave to travel from the epicenter of the earthquake to seismic station D? Interestingly enough though, deep focus earthquakes can occur at depths of hundreds of miles and can be felt literally half a world away.
