WebEarthquakes produce shockwaves called seismic waves. These waves can be detected using seismographs. Some seismic waves are surface waves, while others can travel … WebFigure 2 : This is an actual travel-time curve for body-wave phases (P and S) for an earthquake at the surface. For teaching purposes, just go with the first arrivals in Figure 1, but to get a sense of the complexity see next page.

WebSep 12, 2024 · By looking at the time between the arrivals of the P- and S-waves, one can determine the distance to the earthquake from that station, with longer time intervals indicating longer distance. These distances are determined using a travel-time curve, which is a graph of Pand S-wave arrival times (see Figure 13.11). WebMeasure the difference in arrival times between the first shear (s) wave and the first compressional (p) wave, which can be interpreted from the seismogram. Multiply the difference by 8.4 to estimate the distance, in kilometers, from the seismograph station to the epicenter. 00:00 00:00 An unknown error has occurred Brought to you by Sciencing
