What is the difference between s and p wave?
As P-waves travel at a higher velocity than S-waves they arrive at a seismometer station before the S-waves. The difference between their arrival time can be used to calculate the distance from the seismometer station to the epicentre.
When was Seismometer created?
Seismometer was created in 1880.
How many seismometer measurements are needed to determine an earthquake's epicenter?
Typically, at least three seismometer measurements are needed to determine an earthquake's epicenter. By analyzing the time difference of arrival of seismic waves at each monitoring station, scientists can triangulate the epicenter of the earthquake.
What happens to the time difference between primary and secondary waves as the distance traveled gets longer?
The time difference between primary (P) and secondary (S) waves becomes larger as the distance traveled by the waves increases. This is because P-waves travel faster than S-waves, so the time delay between their arrivals at a seismometer station increases with distance.
Where is the epicenter of an earthquake if the arrival time difference between P and S waves is zero?
Your standing on it! P-waves travel faster than S-waves through the Earth. As such the further away a seismometer station is from the epicentre of an Earthquake, the larger the difference between arrival times will be. By the same logic this means that the closer you get to the epicentre, the smaller the difference in arrival time will be until your at the epicentre when the difference will be zero!
What is the difference between p and s waves arrival time?
As P-waves travel at a higher velocity than S-waves they arrive at a seismometer station before the S-waves. The difference between their arrival time can be used to calculate the distance from the seismometer station to the epicentre.
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.
What is an Accelerometer?
An accelerometer is an instrument used to measure acceleration.
Does the Samsung Intercept have an accelerometer?
Yes, it in fact has an accelerometer
What is the difference between s and p wave?
As P-waves travel at a higher velocity than S-waves they arrive at a seismometer station before the S-waves. The difference between their arrival time can be used to calculate the distance from the seismometer station to the epicentre.
When was Seismometer created?

Who invented the accelerometer?
The accelerometer was invented by George Atwood, who developed the first known accelerometer in the 18th century. Atwood's accelerometer was a simple device consisting of a weight attached to a spring that could measure changes in velocity.
What is the difference between a seismograph and a seismometer?
A seismograph is a device that records vibrations and seismic waves caused by earthquakes, while a seismometer is a sensor that detects ground motion. Essentially, a seismometer is a component of a seismograph, which includes additional recording instruments.
Are accelerometer and blackbox same?
No. The black box is a recorder, while an accelerometer feeds an instrument.
What is the difference between the seismograph and seismometer?
The word seismograph is the old fashioned term for a seismometer. They both perform the same function (recording the amplitude, frequency and duration of seismic waves) however they record the data differently. Seismometers record the data digitally, whereas a seismograph plotted the data directly onto a roll of graph paper. Previous answer: A Seismometer is something used to record motions of the ground. Such as earthquakes and nuclear explosions. So they can measure the size of the explosions.
How do you turn on the iPod Touch's accelerometer or fix it so that it works again?
You can't. If you are having intermittent or permanent problems with your accelerometer, you need to get your unit serviced or exchanged or live without the accelerometer.
