Dear friend The magnitude of earthquakes are measured with these following data's obtained from seismograph picture.We need 2 parameters to decide the magnitude in Richter scale.Those are one highest amplitude recorded and the distance from the point called focus. This distance can be determined by calculating the arrival time of primary and secondary waves.Normally the time difference in seconds multiplied by 8 will give you the distance in Kilo meters. For energy release for each Richter scale please refer the attached chart. I am the person issued the warning 2 hours before Tsunami struck our Indian coast,but my warning was ignored.
Approximate TNT (Tri nitro telecom ) Yield for Seismic Energy
1 30 lbs
2. 1 ton
3. 29 ton
4. 1000 ton
5. 32000 ton
6. 1 million ton
7. 32 million ton
8. 1 billion ton
9. 32 billion ton
10 1 trillion ton.

Generally any pictures you find of an earthquake will be of the damage it caused. You may want to try to find videos that were being filmed during EQs. You can't really "photograph" an earthquake. And its not like a lot of people wait around to film them as they can be random and quick.
