WebMar 10, 2024 · In Italy, a 10-point intensity scale developed in 1902 by Giuseppe Mercalli was adapted by a succession of people. When H. O. Wood and Frank Neumann translated one version into English in 1931, they called it the Modified Mercalli scale. That has been the American standard ever since.
