Richter scale ranges between?

1.	Richter scale ranges between?
Answer» The scale has no UPPER limit but usually ranges from 1 to 9. Because it is logarithmic, an earthquake RATED as 5 is ten times as powerful as one rated as 4. An earthquake with a magnitude of 1 is detectable only by SEISMOGRAPHS; one with a magnitude of 7 is a major earthquake.
