The time lag between the arrival of the P and S waves at a seismometer station can be used to determine the distance of the epicentre from the station. Main Concept. Seismology is the study of earthquakes, their effects, and seismic waves. The location of an earthquake's epicenter (point on the earth's surface directly above the location of rupture or faulting) can be determined using information about two of these seismic waves.. The first type of wave to consider when determining the epicenter of an earthquake is the P. What is a seismic travel time graph used for? A travel time curve is a graph of the time that it takes for seismic waves to travel from the epicenter of an earthquake to seismograph stations at varying distances away. The velocity of seismic waves through different materials yield information about Earth's deep interior. Locating the Epicenter You can now determine the distance from each seismic recording station to the earthquake's epicenter using the known times of travel of the S and P waves. Examine the graph of seismic wave travel times (middle graph on this page). There are three curves on the graph: The upper curve shows S wave travel-time graphed versus. 2 Single station location . In general, epicenters are determined using many seismic phase observations from different seismic stations. However, it is also possible to locate a seismic source using a single 3-component station. Since the vector of P-wave motion is polarized in the vertical plane of. Instruct the students on how to determine the distance to an epicenter using one seismograph reading. This is accomplished using a time-travel graph, which is a graph that shows the relationship between the difference in arrival times of the primary seismic wave and the secondary seismic wave and the distance to the earthquake's epicenter. new. The travel-time curve shown in the figure indicates that the earthquake epicenter is located at a distance of about 60 km from the recording station. This. ... The further away the epicenter is, the weaker the seismic waves will be. ... By looking at the arrival times of the seismic waves at each station, you can triangulate the epicenter's. The distance of the epicenter from the seismic station is equals to 127 km(minimum).

P-waves uses compression and Dilation, but S-waves uses Amplitude and Wavelength. Both types of seismic wave can be detected near the earthquake centre but only P-waves can be detected on the other side of the Earth. This is because P-waves can travel through solids and liquids whereas S-waves can only travel through solids. The distance from this seismic station to the epicenter of the earthquake is approximately. Base your answers to questions 7 through 9 on the data table below, which gives information ... If the distance from the epicenter to station 2 is 3,500 kilometers, what is the approximate difference in the arrival times of the P-waves and S-waves at. Because P and S waves travel at different velocities, The P wave arrives at a seismic station ahead of the S wave. The lag time between them is directly related to the distance that the waves travel. ... Although the lag time can be used to determine the distance to the epicenter of an earthquake, it does not provide information on the. The distance is evaluated by the relative attenuation of the high-frequency components of the wave which diminish with distance. The result is two possible epicenters in opposite directions, but looking at the map, only one corresponds to a plausible source. I read this yesterday but completely forget in which article. map to represent the distance of the earthquake epicenter from each station. Use a drafting compass to draw the circles. This map includes a legend in kilometers. For each station, note the distance to the epicenter. Measure the scale on the map in Figure 9-E4 in centimeters and convert your distances in kilometers to centimeters (e.g., if the. • The closer a seismic station is to an epicenter: 1. The sooner the P-wave will arrive. 2. The smaller the difference between the P-wave and S-wave arrival times.

What data from each seismic station is used to determine the location of the epicenter? _____ An earthquake was recorded at Stations A, B, and C shown on the map below. Station A reported that the epicenter of the quake was 1500 km from the station. Station B reported a distance of 3500 km. Station C reported a distance of 5000 km. As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave. The distance of a seismic station from an earthquake is easily. Determine the distance from the station that recorded that seismogram to the epicenter that caused those seismic waves. Note that the tic-marks on the time scale are in 5-second increments. 3) If you know that the first one-minute mark on Figure 1.4 is 8:52:00 p.m., find the exact time at which this earthquake occurred.. This instructable explains the basic steps seismologists undertake to locate the epicenter of an earthquake: Measure the time that elapses between the arrival of the P (primary) wave and the arrival of the S (secondary) wave to the seismic stations. Using the S-P time, determine the epicentral distance of each station to the earthquake using a. The first P-wave arrived at a seismic station at 10:00:00.
