Earthquake Travel Times | U.S. Geological Survey - USGS.gov
Travel time curves of earthquakes. (Public domain.) P and S-P travel times as a function of source distance for an earthquake 33 km deep. The Time of the first arriving P phase is given, along with the time difference between the S and P phases. The latter time is known as the S minus P time.

Travel-time curve - Wikipedia
Travel time in seismology means time for the seismic waves to travel from the focus of an earthquake through the crust to a certain seismograph station. [1] Travel-time curve is a graph showing the relationship between the distance from the …
Travel-time Curves: How they are created - IRIS
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.
A travel-time curve is a graph of the time that it takes for seismic waves to travel from the epicenter of an earthquake (time and distance = zero) to seismograph stations varying distances away. The curves are the result of analyzing seismic waves from thousands of earthquakes, received by hundreds of seismic stations around the world.

To construct and utilize a graph to characterize the relationship between distance and time of travel of seismic waves (a travel time-curve). To use the constructed time-travel graphs to locate the epicenter of a simulated earthquake by triangulation.
a) Time of quake: 1:20:40 PM (20 minutes and 40 seconds after 1 PM) b) Distance from epicenter to seismic station: 5200 km c) P wave travel time from epicenter to station: 8:40 (8 minutes and 40 seconds)
From analyzing many earthquakes in a given region seismologists know the relationship between the S‐P interval and the distance to an earthquakes epicenter. The basic tool that they use is the travel‐time graph (Figure 10). On such a graph, time is plotted along the y‐axis and
