What among the following is FALSE about the Richter scale? A. It was developed by Charles Richter and Gutengberg in 1935. B. It is a logarithmic scale C. It can be measured using a seismometer D. Magnitude of 8-9 on a Richter scale means it is a micro earthquake.

The Richter scale was developed in 1935 by Charles Richter with Beno Gutenberg. It is logarithmic (each whole number is ten times the amplitude of the one below), and the shaking it uses is recorded by seismometers. A magnitude of 8–9 is a great, highly destructive earthquake; micro-earthquakes are below magnitude 2. So statement D is false.
