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.
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.
What is a long wave caused by an underwater earthquake or other disturbance called?
A tidal wave is caused by an earthquake.
Which of the three recording stations was closest to the epicenter of the earthquake based on the seismograms shown below?
To determine which recording station was closest to the epicenter of the earthquake, you would typically analyze the arrival times of the seismic waves recorded at each station. The station with the shortest time interval between the arrival of the primary (P) wave and the secondary (S) wave would be the closest to the epicenter. If you have specific data points or seismograms, you can calculate the distance based on these wave arrivals.
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 can the arrival and progress of an earthquake be recognized on a seismogram?
The arrival and progress of an earthquake can be recognized on a seismogram through distinct patterns of seismic waves. Initially, the P-wave (primary wave) appears first as a series of rapid, small spikes, indicating the first seismic activity. Following this, the S-wave (secondary wave) arrives, characterized by larger, slower oscillations, which typically have greater amplitude. The time difference between the arrival of these waves helps seismologists determine the earthquake's distance from the recording station.
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 s-p time 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.

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.
What can be determined using a seismogram?
A seismogram can be used to determine several key details about an earthquake, including its magnitude, depth, and distance from the recording station. It provides information on the arrival times of different seismic waves, allowing scientists to identify the type of earthquake and its location. Additionally, the seismogram can reveal characteristics of the Earth's subsurface structure based on the wave patterns recorded.
