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. IRIS' travel times graphic for the 1994 Northridge, CA earthquake.

Enter the latitude and longitude of the earthquake and station and the focal depth of the earthquake. = 6.0 min. Calculate the difference between the arrival time of the P-wave and the S-wave.Referring to the Earthquake Time Travel Graph below, determine the location on the graph where the two lines have a difference in their y values equal to the time difference you. Earthquake-station distances need to be calculated separately by first picking P and S arrival times on seismograms, and then using a P and S wave travel time graph to determine the distance. We are showing the 1000 latest earthquakes with a magnitude of at least 5. To plot a different selection of events, visit Interactive Earthquake Browser. Basic worksheet that leads students through the processes of calculating distances to an epicenter, travel times for P &amp; S waves and origin times of an Earthquake.

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. In this activity you will construct a Travel-Time Graph for seismic waves similar to the one shown below. This graph will be used to determine the distance to an epicenter based on the amount of time that earthquake waves have traveled.

This vodcast briefly goes over how to find distance to an epicenter and time traveled by a seismic body wave using an S-P time curve.

The network-theoretical method enables us to estimate H and β more easily than other standard methods such as calculating power spectrum [].Therefore, it has been applied to extract the fBm-like nature of time series in several contexts such as finance [], health science [18, 19], image processing [], and geophysics [21, 22].In this paper, we study the nature of. mph.

Plot the calculated travel times at the five distances (place a dot at the distance and location given by the data in columns 1 and 5 of Table 1 on the graph shown in Figure 4. Draw a smooth curved line through the calculated travel times (from the graphical calculations, Table 1).

Make sure you subtract any rests or stops you made from the total trip duration. If the total distance travelled was 500 miles and the time it took you was 5 hours, then your average speed was 500 / 5 = 100 miles per hour (mph). If the distance was 300 kilometers and it took you 5 hours to cover it, your speed was 300 / 5 = 60 km/h (kilometers. Description. Frequency is cycles per second .

P-waves are a type of elastic wave, called seismic waves in seismology, that can travel through a continuum. The continuum is made up of gases (as sound waves), liquids, or solids, including the Earth. P-waves can be produced by earthquakes and recorded by seismographs. The name P-wave is often said to stand either for primary wave, as it has the highest velocity and is therefore the first to.
