The Mercalli Intensity Scale was developed by the Italian volcanologist Giuseppe Mercalli in 1884 and expanded to include 12 degrees of intensity in 1902 by Adolfo Cancani. It was modified again by Harry O. Wood and Frank Neumann in 1931. It is known today as the Modified Mercalli Intensity Scale. Mercalli ratings, which are given as Roman

Broad fissures in ground. Underground pipelines completely out of service. Earth slumps and land slips in soft ground. Rails bent greatly. The United States Geological Survey (USGS) said, " The earthquake was felt (IX) at Banda Aceh, (VIII) at Meulaboh and (IV) at Medan, Sumatra and (III-V) in parts of Bangladesh, India, Malaysia, Maldives, Myanmar, Singapore, Sri Lanka and Thailand. The Mercalli Scale was used earlier than the Richter Scale.

I've covered the Richter scale now I look at What is the Mercalli Scale?https: A scale based upon the work of Rossi and Forel was presented to the Second International Seismological Conference in Stra~sburg (Cancani, 1904). It greatly influenced European practice and is the basis of Sieberg's (1923) scale. From this, in turn, Wood and Neumann's (1931) Modified Mercalli scale, used in America and New Zealand, was derived.

The Modified Mercalli Intensity Scale of 1931 is the basis for the U.S. evaluation of seismic intensity. Intensity is different than the magnitude in that it is based on observations of the effects and damage of an earthquake, not on scientific measurements.

It was developed in 1931 by the American seismologists Harry Wood and Frank Neumann. The modified Mercalli intensity scale(MMor MMI), developed from Giuseppe Mercalli's Mercalli intensity scaleof 1902, is a seismic intensity scaleused for measuring the intensity of shaking produced by an earthquake. It measures the effects of an earthquake at a given location, distinguished from the earthquake's inherent force or strength as measured by seismic magnitude scales(such as the "Mw" magnitude usually reported for an earthquake). The Modified Mercalli Intensity Scale of 1931 is the basis for the U.S. evaluation of seismic intensity. Intensity is different than the magnitude in that it is based on observations of the effects and damage of an earthquake, not on scientific measurements.
