What else can I help you with?
What is the point where earthquake movement occurs first?
The epicenter.
Distance from 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.
When finding an epicenter do you subtract s wave minus the p wave?
No, to find the epicenter of an earthquake, you use the difference in arrival times between the P-wave and the S-wave at a seismograph station. The greater the time difference between the two waves, the farther the earthquake's epicenter is from that particular station. Subtraction is not directly involved in this process.
Which type of wave would be created at the epicenter?
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.
Is The point directly above the focus of an earthquake is called the S wave?
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.
Which type of wave causes the ground to shake in a motion parallel to the focus moving straight away from the epicenter?
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.
Why does the time between the arrival of the P wave and the S wave become greater and greater as you get farther away from the epicenter?
It is because the epicenter decreases their strenght as it is closer to it
What is the point where earthquake movement occurs first?
The epicenter.
Which two waves from an earthquake can triangulate the epicenter?
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).

What starts a tidal wave?
The tidal wave starts by the moon

How do scientists locate the epicenter of an earthquake by s-p time method?
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.
The point directly above the focus of an earthquake is called the S wave?
This statement is incorrect. The point directly above the focus of an earthquake is called the epicenter, not the S wave. S waves are one type of seismic wave that travel through the Earth's interior during an earthquake.
What is the circular wave?
A circular wave is a type of wave that propagates outwards in all directions from a central point. It is characterized by a wavefront that forms a series of concentric circles expanding outwards. Circular waves are often observed in phenomena such as ripples on water or seismic waves emanating from an earthquake epicenter.
How is the distance between the seismic station and the earthquake epicenter determined?
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.
