What else can I help you with?
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.
Which body waves is a longitudinal wave?
The primary body wave that is a longitudinal wave is the P wave. P waves are compressional waves that travel through solid and liquid materials by causing particles to move in the same direction of wave propagation.
Which body wave is a longitudinal wave?
The primary body wave that is a longitudinal wave is the P-wave (primary wave). It is the fastest seismic wave and travels through the Earth's interior by compressing and expanding the rock in the direction of the wave's propagation.
Is a P wave longitudinal or transverse?
A P wave is a type of seismic wave that is classified as a longitudinal wave. Longitudinal waves are characterized by the vibration of particles in the same direction as the wave is moving.
What is the formula of wave intensity?
Not sure what formula you are looking for. Wave intensity is given by the amplitude of the wave.
What is S P lag time?
the difference between the arrival of the p-wave and s-wave
How do you determine an p-s interval on a seismogram?
To determine the P-S interval on a seismogram, first identify the arrival times of the P-waves and S-waves. The P-wave is the first seismic wave to arrive, so locate its initial peak on the seismogram. Next, find the point where the S-wave arrives, which is characterized by a distinct increase in amplitude following the P-wave. The time difference between the two arrivals, known as the P-S interval, can then be calculated by subtracting the P-wave arrival time from the S-wave arrival time.
What is S-P lag time?
the difference between the arrival of the p-wave and 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.
What are the steps of the S-P time method?
The S-P time method is used to determine the distance to an earthquake epicenter. The first step is to measure the time difference between the arrival of the primary (P) waves and the secondary (S) waves at a seismograph station. The second step is to use a travel-time graph to determine the distance to the epicenter based on the time interval between the P and S waves. Finally, by using data from at least three seismograph stations, the exact location of the earthquake epicenter can be triangulated.
What difference between P-waves and S-waves is used to find an earthquake's epicenter?
The difference in arrival times of P-waves and S-waves can be used to find an earthquake's epicenter. P-waves travel faster than S-waves, so by measuring the time lag between the arrival of the two wave types at different seismic stations, scientists can triangulate the epicenter of the earthquake.
What is the difference between arrival times of a p-wave and a s-wave?
s waves are about 60% slower than p waves, so basicaly p waves are about twice as fast. The actual time in like minutes or hours depends on where the epicenter is, and where you are recording from
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.
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
How do you measure an S-P interval?
To measure the S-P interval, you would first identify the onset of the S wave and the onset of the subsequent P wave on an electrocardiogram (ECG) tracing. Then, you would determine the time interval between these two points, typically using calipers or measuring tools available on ECG machines. The S-P interval represents the time it takes for electrical stimuli to travel from the AV node to the Purkinje fibers in the heart.
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.
How do scientists find the distance of an epicenter from a seismograph?
They measure the difference in arrival times of P and S seismic waves as measured on a seismograph. From this (based on an estimate of their relative velocities) they can calculate the distance of the seismometer from the earthquakes epicentre using the following equation:Distance to epicentre (km) = Time Difference (s) x (VP - VS) / (VS x VP)Where:VP = P-wave velocity (km/s)VS = S-wave velocity (km/s)
