A tiltometer measures the bulging of a volcano, which is how much the volcano is 'growing' wider and wider due to the magma chamber within a volcano filling with magma, if the tiltometer is reading that the volcano is bulging massively then this could be because it is about to errupt so it can be used to predict volcanic eruptions. A seismometer on the other hand measure tremors before an eruption due to magma movement and it can be used to predict earthquakes due to foreshocks.

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.
What is the difference in arrival time between P and S waves equivalent to?
This value is related to the distance of the seismometer station from the earthquake's epicentre. The larger the difference in arrival times, the greater the distance.
What is the difference between a seismograph and a 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.
What would you use to determine the distance that seismic waves have traveled from the origin to that station?
The difference in arrival times between P and S-waves as measured on a seismometer can be used to determine the distance to the origin.
What is the difference between a seismograph and a seismogram?
Most of vibrations can be detected and recorded by sensitive instruments called seismograph, or seismometers. The record produced by a seismometer is called a seismogram.

What is the difference between a seismometer and a accelerometer?
A seismometer is the modern instrument used to measure seismic waves. A seismogram is a print out of the seismic data recorded by the seismometer. Usually in the form of the motion per unit time in all three dimensions.
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 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.

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 machine detects earthquakes?
A seismometer (the term seismograph may be used to describe a seismometer combined with an instrument for recording and displaying the amplitude and frequency of the seismic waves that the seismometer measures). Please see the related link.
