The Mercalli intensity scale (or more precisely the Modified Mercalli intensity scale) is a scale to measure the intensity of earthquakes. Unlike with the Richter scale , the …

The Mercalli intensity scale was created to measure the intensity and effects of an earthquake. The intensity is not completely determined by the magnitude. This scale attempts to quantify the effects on a scale from I (Roman numeral 1), where it’s not felt, to XII, which is total destruction. The values depend on distances from the epicenter ...Modified Mercalli Intensity Scale. CREDIT: Northern Illinois University. Earthquake magnitude measures the strength of an earthquake, or the amount of energy that is released. This measurements stays the same no matter where you are in the world. Earthquake intensity measures the amount of damage that an earthquake causes and what people feel ...The effect of an earthquake on the Earth's surface is referred to as its intensity. Numerous intensity scales have been developed over the last several hundred years. The one currently used in the United States is the Modified Mercalli Intensity Scale developed in 1931.

The Mercalli Scale . Giuseppe Mercalli, an Italian volcanologist, introduced the Mercalli Intensity Scale in 1885. The scale was expanded to accommodate 12 degrees of intensity by Adolfo Cancani in 1902. The scale was designed to determine the extent of damage in the aftermath of an earthquake. Mercalli ratings are assigned by Roman numerals.Intensity Shaking Description Image; I: Instrumental: Not felt except by a very few under especially favorable conditions. II: Feeble: Felt only by a few persons at rest, especially on upper floors of buildings. Delicately suspended objects may swing. III: Slight: Felt quite noticeably by persons indoors, especially on the upper floors of ...The scale now generally employed in North America is the Mercalli scale, as modified by Harry O. Wood and Frank Neumann in 1931, in which intensity is considered to be more suitably graded. A 12-point abridged form of the modified Mercalli scale is provided below. Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs. So the intensity of an earthquake will vary depending on where you are. Although numerousintensity scales have been developed over the last several hundred years to evaluate the effects of earthquakes, the one currently used in the United States is the Modified Mercalli (MM) Intensity Scale. It was developed in 1931 by the American seismologists Harry Wood and Frank Neumann. Feb 10, 2011

The Modified Mercalli (MM) Intensity Scale is used in the United States. Based on Giuseppe Mercalli's Mercalli intensity scale of 1902, the modified 1931 scale is composed of increasing levels of intensity that range from observable quake impacts from light shaking to catastrophic destruction. Intensity is reported by Roman numerals.Sep 29, 2023 · A modified Mercalli intensity scale is used to quantify the earthquake's effects. That's why you can't directly convert the Richter or Magnitude scale to the Mercalli scale — although the released energy, local geology, terrain, depth of an earthquake and distance from the epicenter are all still the same. Thus, the Mercalli scale describes ...
