<u>Answer:</u>
<em>It is detected by a seismograph.
</em>
<em>It is measured by the Mercalli scale.
</em>
<em>It is based on the size of seismic waves.</em>
<em></em>
<u>Explanation:</u>
The earthquake's magnitude can be described as follows.
<em>1. It is detected by a seismograph.
</em>
Magnitude follows the logarithmic scale of base 10. Alternatively, any motion caused by the earthquake increases by 10 times on a seismograph.
<em>2. It is measured by the Mercalli scale.
</em>
This scale follows the observations of survivors or witnesses of the earthquake.
<em>3. It is based on the size of seismic waves.
</em>
Richter scale takes into account the strongest wave recorded by the seismometer and seismometer's proximity to the earthquake.
