Seismic Wave(:
The epicenter.
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.
Assuming you are some distance from the epicenter, the first effect will be a side to side motion of the ground. That wave is called the P-wave. The last wave to arrive is the rolling type, similar to waves on the occean's surface, known as a Raleigh Wave.

p-wave
It is because the epicenter decreases their strenght as it is closer to it

where the fault is at or the epicenter which is not where the earthquake starts it is the focus where the earthquake starts
The tidal wave starts by the moon
p wave
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.
