Which type of seismic waves arrives at distant points before any other seismic waves?
Primary waves are seismic waves and the arrive first after an earthquake occurs.
Which earthquake waves are the first to be recorded on a seismometer and are the fastest?
P-waves which are a compression or pressure wave are the fastest seismic waves. As they are the fastest they will reach the seismic station before any of the other seismic waves and be recorded first. Seismologists can use the difference between the arrival times of different seismic waves to calculate the distance and ultimately the location of the earthquakes epicentre. For information on this, please see the related question.
How are P-waves and S-waves related to earthquakes?
They are the names given to the two types of seismic body waves released when an earthquake occurs. P-waves are known as primary waves as they have the highest verlocity of any seismic waves and so are the first to be recorded by a seismometer and they are longitudinal or compression waves. S-waves are known as secondary waves having a lower velocity than the P-wave and so arriving at a seismometer station after the P-waves. S-waves are transverse or shear waves.
Which seismic wave arrives last at a seismograph station?
The first waves to arrive at a seismograph station are primary waves, or P waves.
How is the distance between a seismic station and the earthquake epicenter is 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.
What seismic waves reach the seismometer first after an earthquake?
P waves
Which type of seismic waves arrives at distant points before any other seismic waves?
Primary waves are seismic waves and the arrive first after an earthquake occurs.
Which seismic wave type arrives first during an earthquake?
The P Waves. Then the S Waves.
What is the process that is used to find an earthquake's epicenter?
Triangulation. First, they calculate the time between the first and second - primary and secondary - seismic waves created in an earthquake and use this information to determine how far the seismometer is from the epicenter of the earthquake. A circle is drawn around the seismometer so that it is in the center and the radius is equal to the calculated distance. Using this information from three different seismometers, two more circles are drawn and the intersecting point of the three circles is where the epicenter of the earthquake is located.
Which earthquake waves are the first to be recorded on a seismometer and are the fastest?
P-waves which are a compression or pressure wave are the fastest seismic waves. As they are the fastest they will reach the seismic station before any of the other seismic waves and be recorded first. Seismologists can use the difference between the arrival times of different seismic waves to calculate the distance and ultimately the location of the earthquakes epicentre. For information on this, please see the related question.
Why are P-waves called P-waves?
They are given this name in seismology because they are the fastest travelling of the seismic body waves released by an earthquake. Because they are the fastest, they are detected by seismometer stations first. Hence P for primary wave.
What Instrument measures the density of an earthquake?
The instrument that can measure the density of an earthquake is called an seismometer. The first seismoscope dates back to 132 AD.
Why are 3 seismometers required to locate exactly where an eartquake occurred?
The seismometer records the P and S-wave arrival times. P-waves travel faster through the earth than S-waves and so they arrive at the seismometer station before the S-waves and are recorded by the seismometer first. The difference in arrival time between the two types of seismic wave can be used to calculate the distance of the earthquake's epicentre from the seismometer. This can then be plotted on a map, by drawing a circle with a radius equal to the distance to the epicentre around the seismometer station. This is then repeated for the other two seismometer stations and the point where the three circles intersect is the location of the earthquakes epicentre.
How are P-waves and S-waves related to earthquakes?
They are the names given to the two types of seismic body waves released when an earthquake occurs. P-waves are known as primary waves as they have the highest verlocity of any seismic waves and so are the first to be recorded by a seismometer and they are longitudinal or compression waves. S-waves are known as secondary waves having a lower velocity than the P-wave and so arriving at a seismometer station after the P-waves. S-waves are transverse or shear waves.
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 seismic wave arrives last at a seismograph station?
The first waves to arrive at a seismograph station are primary waves, or P waves.
Who thought of seismic waves?
well it's a scientist. it first came from the word seismic. there was no wave added until an earthquake happened to cross the scientist who made the word seismic.
