The magnitude is based on the size of the largest wave recorded on a seismometer. Seismometers are instruments that detect and record ground vibrations. The lower magnitude earthquakes are usually not felt by people and the higher magnitude earthquakes could be very destructive (Michigan Technological University). It’s hard to say how destructive an earthquake could be because it could be in a field or in a big city. People are still trying to predict earthquakes but they have an idea where earthquakes might occur but they are not sure when (planet science.com). People have seen animals behaving weirdly before an earthquake but we are still not sure if animals can actually predict them.
