actually no. the p waves gets subtracted from the s wave. remener promary comes before secondary waves!
According to the chart, this earthquake's epicenter was 215 kilometers away. Measure the amplitude of the strongest wave. The amplitude is the height (on paper) of the strongest wave. On this seismogram, the amplitude is 23 millimeters.
This is true; a seismic wave weakens the farther it travels, and thus has lower intensity.
No, the point directly above the focus of an earthquake is called the epicenter. The S wave is one of the types of seismic waves that are generated during an earthquake and move slower than the P wave.
At the epicenter of an earthquake, both primary (P-wave) and secondary (S-wave) seismic waves are typically generated. P-waves are faster and arrive first, while S-waves are slower and arrive next. These waves cause the ground to shake in different ways, with P-waves traveling through solids, liquids, and gases, while S-waves only travel through solids.
The distance between a seismic station and the earthquake epicenter is determined from the S-P interval, which is the time difference between the time of arrival of the first P wave and the first S wave.
They first collect several seismogram tracings of the same earthquake from different locations. Then the seismograms are placed on a time distance graph. The seismogram tracing of the first p wave is lined up with the p wave time distance curve. The difference from each station from the earth quake can be found by reading the horizontal axis. After finding out the distance, a seismologist can locate an earthquake's epicenter.
It is because the epicenter decreases their strenght as it is closer to it
P-waves (Primary) and S-waves (Secondary). Using the difference in time between the arrival of P- and S-waves, you can then determine the distance from the epicenter. Once you've determined the distance from the epicenter of three different stations, you'll be able to triangulate the epicenter (the point where all three circles cross).

The distance of an epicenter from a seismograph station can determined by the time it takes for the seismic waves to reach each station. You need at least 3 seismic stations to record the event to determine this. The time taken for each seismic station to resisted the event will be different as they are different distances from the epicenter. The distance to the epicenter can then be calculated for each station and a epicenter can be determined by a triangulation from all stations that have registered the event.
The type of wave that causes the ground to shake in a motion parallel to the focus moving straight away from the epicenter is a primary (P) wave. P waves are compressional waves that travel through the Earth and are the fastest seismic waves. They are the first to be detected by seismographs during an earthquake.
