Typically, at least three seismometers are needed at a given place to fully record the motions arising from earthquake waves. With three seismometers, data can be used to triangulate the epicenter and determine the magnitude of the earthquake. More seismometers can provide more detailed and accurate information about the seismic event.
Typically, at least three seismometers are needed to accurately determine the location and magnitude of an earthquake. By measuring the arrival times of earthquake waves at different locations, seismologists can triangulate the epicenter and assess the seismic activity more effectively.
To measure earthquakes, you need seismometers, devices that detect and record seismic waves caused by earthquakes. These seismometers are typically placed in various locations to accurately measure the magnitude and intensity of the shaking. The data collected from these instruments is then used to determine the earthquake's location, depth, and magnitude.
They need 3

There is no need to capitalize earthquake.
About 2,000-4,000 people where injured and need new limbs
1 good one.
There are many different disciplines in gymnastics and consequently many different record holders. You need to specify which one you are referring to.
