The first wave to reach a recording station after an earthquake is the Primary wave, or P-wave. P-waves are compressional waves that travel faster than other seismic waves, moving through both solid and liquid layers of the Earth. They are followed by Secondary waves (S-waves) and surface waves, which arrive later and can cause more damage.
What else can I help you with?
When will the first p wave be received if an earthquake epicenter is approximately 1800 kilometers from the seismic station?
3.5 minutes after the earthquake.
Which earthquake wave is not a seismic wave?
the sound wave
A seismograph station recorded the arrival of the first P-wave at 7 32 pm From an earthquake that ocvured 4000 kilometers away What time was it at the station when the earthquake occurred?
P-waves, or primary waves, travel faster than other seismic waves, typically at speeds of about 6 to 8 kilometers per second. If the earthquake occurred 4,000 kilometers away and the P-wave arrived at 7:32 PM, it would have taken approximately 500 to 667 seconds (about 8 to 11 minutes) to reach the station. Subtracting this time from 7:32 PM, the earthquake likely occurred between 7:21 PM and 7:24 PM at the station.
What is a long wave caused by an underwater earthquake or other disturbance called?
A tidal wave is caused by an earthquake.
If a p wave arrives at a seismograph station at 907 am and the S waves arrives at the same seismograph stations at 909 an about how fare is that station from the epicenter of the earthquake?
To estimate the distance from the seismograph station to the earthquake epicenter, we can use the typical speed of P waves (approximately 6 km/s) and S waves (approximately 3.5 km/s). The time difference between the P wave and S wave arrival is 2 minutes (or 120 seconds). Given that P waves travel faster, we can calculate the distance using the time difference, which would be approximately 360 km from the epicenter to the station.
How do you find the lagtime of an earthquake?
To find the lagtime of an earthquake, subtract the origin time of the earthquake from the arrival time of the seismic waves at a specific location. This lagtime represents the delay between the earthquake occurrence and the arrival of seismic waves at that location. The lagtime is a crucial parameter for determining the distance of the earthquake epicenter from the recording station.
When will the first p wave be received if an earthquake epicenter is approximately 1800 kilometers from the seismic station?
3.5 minutes after the earthquake.
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.
The first s-wave arrive at a seismograph station 11 minutes after an earthquake occurred how long after the arrival of the first p-wave did the first s-wave arrive?
The P-wave generally arrives before the S-wave during an earthquake. The time difference between them can help determine the distance to the earthquake's epicenter. In this case, if the S-wave arrived 11 minutes after the earthquake, you would need to calculate the time difference between the arrival of the P-wave and the S-wave to determine how long after the P-wave arrival the S-wave arrived.
Can the S-P times method be used with one seismograph station to locate the epicenter of an earthquake?
The first step in this method is to collect several seismograms 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, and the tracing of the first S wave is lined up with the S-wave curve.The distance of each station from the earthquake can be found by reading the horizontal axis. After finding out the distances, a seismologist can locate an earthquake's epicenter.-New Boyz

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.
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.
How do you calculate the distance from an earthquake?
The distance from an earthquake epicenter can be calculated using the time difference between the arrival of P-waves and S-waves at a seismograph station. By measuring this time lag and using the known velocity of seismic waves through the Earth's interior, the distance can be estimated. The greater the time lag between the arrival of the P-wave and S-wave, the farther the seismograph station is from the earthquake epicenter.
Which earthquake wave is not a seismic wave?
