Which scale of measurement measures the magnitude or strength of an earthquake based on seismic waves? mercali richter moment magnitude focus

The answer is Ritcher. The Ritcher scale was developed by Charles Ritcher from which it was named after in 1935. The measurement of earthquakes using the Ritcher magnitude scale is based on a logarithmic scale of between 0 and 10. This is measured using a seismogram. In earthquakes of 3.0 and below in magnitude, the shaking is almost undetectable by humans. Magnitude above 8.0, on the other hand, are very powerful and the shockwaves can be visible on the ground.

i believe that if you say you can, you cant and if you say you can't your right. i believe i can do anything i set my mind to. i've applied this with my everyday life. it me get motivated to do stuff.for example, i apply this to do school. if i believe i can finish a whole class in a couple of week's i will be motivated to do the class until i finish it, and if i believe i can't, i will get distracted and do other stuff besides doing my work. it changed me by believing i can accomplish anything i set my mind to.
