It starts from the center, I'm pretty sure, and then moves out from there. BORDERLANDS 2 ALL THE WAY!
The instrument that does not belong in this group is the seismograph. An anemometer, barometer, and thermometer are all instruments used to measure weather-related phenomena such as wind speed, air pressure, and temperature, respectively. A seismograph, on the other hand, is used to measure and record seismic waves caused by 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.
To find the distance to an earthquakes epicentre, you need the data from a seismometer.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 on the seismogram first.The difference in arrival time between the two types of seismic wave can be used to calculate the distance of the earthquakes epicentre from the seismometer.DE = DeltaT x (VP - VS) / (VS x VP)Where:DE = Distance to epicentre (km)DeltaT = Difference between P and S-wave arrival time (s)VP = P-wave velocity (km/s)VS = S-wave velocity (km/s)Please see the related question for further information.
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.
The Richter magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded on a seismograph. It provides a quantitative measure of the size or energy released during an earthquake. The Richter scale is commonly used for smaller to moderate earthquakes.
A seismograph is a device that measures and records seismic waves caused by earthquakes, while a seismogram is the record of the data produced by a seismograph. Together, they are essential tools in studying and monitoring earthquakes and other seismic activities around the world.

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)

No. A minimum of three seismometer stations are required to locate an earthquakes epicentre. Please see the related question for more information.
A seismologist is a scientist who studies earthquakes and seismic waves. They use tools such as seismometers, GPS, and satellite imagery to detect and locate earthquakes. Seismologists also analyze data from networks of seismic stations to understand the behavior of earthquakes.
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.
No. One seismograph station will only allow you to calculate the distance to the earthquake's focus. (The epicentre is on the surface above.) To find its exact location you need the recordings from at least 3 seismograph stations.For more information on the SP time method, please see the related question.

Well, honey, the antonyms of seismograph are anything that ain't related to measuring earthquakes. So, you could say "banana" or "unicorn" if you're feeling spicy. But really, just think of words like "silence" or "stillness" - they're about as far from a seismograph as you can get.
Scientists use a method called triangulation to locate the epicenter of an earthquake. By analyzing the arrival times of seismic waves at multiple seismograph stations, they can determine the distance from each station to the epicenter. The intersection of these distance measurements helps pinpoint the epicenter location.
