It starts from the center, I'm pretty sure, and then moves out from there. BORDERLANDS 2 ALL THE WAY!

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.
What do seismologists measure?
A seismograph is a device that scientists use to measure earthquake severity. It also determine the origination of the tremor and magnitude.
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.
How is the fact that P-waves travel faster that S-waves used to determine the distance of an earthquake epicenter from an seismograph station?
Using the difference in their arrival times and an estimate of their velocity of propagation you can calculate the distance of the earthquake epicentre from the seismometer recording station. If you do this from three or more different seismometer stations you can triangulate it's position. For more information please see the related question.
What are earthquakes related to?
Earthquakes are related to plate movements as it is caused by them.

What ways are earthquakes measured?
Earthquakes are measured using a seisometer which detects tilts/movements of the plates within the earthquakes Charlotte x
What is a seismologist and what types of scientific tools do they use to locate earthquakes?
Seismologist use a seismometer or seismograph to record the P and S-wave arrival times.Please see the related question for detail on how this is used to locate an earthquake epicenter.Geologists use seismic waves to locate an earthquake's epicenter.
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)
How are strengths of earthquakes measured?
The magnitude of an earthquake is measured with a seismograph and the readout is measured using the Richter scale - See Sources and related links for more information
What do seismologists measure?
A seismograph is a device that scientists use to measure earthquake severity. It also determine the origination of the tremor and magnitude.
Can you locate an earthquake with one seismograph station?
No. A minimum of three seismometer stations are required to locate an earthquakes epicentre. Please see the related question for more information.

What instrument is used to detect vibrations in an earthquake?
Seismometers. For information on how seismometers are used, please see the related question.
Are earthquakes and super moons related?
No, but earthquakes and MOONquakes are related
