Webb21 jan. 2024 · Each seismograph records the times when the first (P waves) and second (S waves) seismic waves arrive. From that information, scientists can determine how fast the waves are traveling. Knowing this helps them calculate the distance from the epicenter to each seismograph. WebbBy understanding how seismic waves travel these records of ground motion, called seismograms, can be interpreted to enable us to locate the earthquake’s source. In this activity, students use recent 3-component seismograms (recordings of motion on the N/S, E/W, and up/down axis) to locate quakes.

Webbit's a method of determining the epicenter of an earthquake by finding the intersection of circles using seismic data Sets found in the same folder Seismograms and Earthquake … Webb43. The diagram on the right shows the record of one earthquake on seismograms at three different stations in a seismic network. These three seismograms show: a) ISCO station is closest to the earthquake b) WUAZ station was right at the earthquake c) DUG station is farthest from the earthquake d) WUAZ is the closest station, followed by DUG, and then … Webb12 sep. 2024 · A circle is drawn from each of the three different seismograph locations, where the radius of each circle is equal to the distance from that station to the epicenter. The spot where those three circles intersect is the epicenter (Figure 13.12). This page titled 13.4: Locating an Earthquake Epicenter is shared under a CC BY-SA license and was ... alfy unigranrio
