Rossi and Forel later collaborated and produced the Rossi-Forel Scale in 1883. The Rossi-Forel Scale used ten degrees of intensity and became the first scale to be widely used internationally. In 1902, Italian volcanologist Giuseppe Mercalli created a twelve-degree scale of intensity.

In 1883 M. S. de Rossi and F. A. Forel published a 10-step intensity scale which was widely used in the 19th and early 20th centuries. ... In 1902, Giuseppe Mercalli greatly improved the Rossi-Forel Scale, later increasing the number of steps to 12, and the intensity scale has since been known as the Mercalli Scale.

Mercalli intensity scale - Wikipedia, the free encyclopedia
The Mercalli intensity scale is a scale used for measuring the intensity of an earthquake. The scale quantifies the effects of an earthquake on the Earth's surface, humans, objects of nature, and ma...
en.wikipedia.org/wiki/Mercalli_intensity_scale
The Mercalli scale originated with the widely used simple ten-degree Rossi-Forel scale, which was revised by Italian volcanologist Giuseppe Mercalli in 1883 and 1902. The terms ''Mercalli intensity scale'' or ''Mercalli scale'' should not be used unless one really means the original ten-degree scale of 1902.
