	Jay's Java Earthquake
		One of the first intensity scales was developed by the Italian scientist De Rossi and the Swiss scientist Forel, known as the Rossi-Forrel scale.
		In 1902 the Italian scientist Mercalli improved this scale, and in 1931 the American scientists H.O. Wood and F. Neumann adapted the scale for use in California.
		Before there were seismometers which could measure the vibration of the earth caused by earthquakes, scientists used descriptive measures of the effects of the vibration as a means of quantifying their size or severity.

	Richter magnitude scale - Encyclopedia.WorldSearch
		Intensity scales, such as the Rossi-Forel and Modified Mercalli Intensity Scale, are used to describe relative earthquake effects.
		By the beginning of the 21st century, most seismologists considered the traditional magnitude scales to be largely obsolete, being replaced by a more physically meaningful measurement called the seismic moment which is more directly relatable to the physical parameters, such as the dimension of the earthquake rupture, and the energy released from the earthquake.
		It is a base-10 logarithmic scale obtained by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a seismogram.

	Mercalli intensity scale - Wikipedia, the free encyclopedia
		The Mercalli scale originated with the widely used simple ten-degree scale by Rossi and Forel, which was revised by Italian volcanologist Giuseppe Mercalli in 1883 and 1902.
		The Mercalli intensity scale is one of many scales used to classify the intensity of an earthquake by examining its effects on the Earth's surface, humans, objects of nature, and man-made structures.
		The Mercalli-Wood-Neuman (MWN) scale was later improved by Charles Richter, the father of the Richter magnitude scale.

	South Carolina Geological Survey Earthquake Intensities
		The Rossi-Forel Scale initially used to describe the January 1, 1913, Union County, S.C., earthquake is considered comparable to the Modified Mercalli Intensity Scale for the purpose of developing this map.
		Earthquake Intensities in SC ntensity is a numerical index describing the effects of an earthquake on the surface of the Earth, on man, and on structures built by man. The intensities shown on the map below are the highest likely under the most adverse geologic conditions.
		The intensities shown on this map are the highest likely under the most adverse geologic conditions that would be produced by a combination of the August 31, 1886, Charleston, S.C., earthquake and the January 1, 1913, Union County, S.C., earthquake.

		The one important intensity scale that does not have twelve degrees (now that the Rossi-Forel Scale is no longer much in use) is the seven-degree Japanese Meteorological Agency Scale (JMA Scale).
		This new scale was based on MCS, MM56 and previous work by Medvedev in Russia, and added a new quantitative aspect to make the scale more powerful.
		It therefore fell to A Sieberg to construct a twelve degree intensity scale with full descriptions of each degree; the first version was published by him in 1912 and subsequently revised twice.

	Glossary
		Most frequently used are at present the European Macroseismic Scale (EMS-98), and in the United States the Modified Mercalli scale and the Rossi-Forel scale.
		The moment magnitude (Mw) scale, based on the concept of seismic moment, is uniformly applicable to all earthquake sizes but is more difficult to compute than the other types.
		In principal, all magnitude scales could be cross calibrated to yield the same value for any given earthquake, but this expectation has proven to be only approximately true, thus the need to specify the magnitude type as well as its value.

		The two character fields give the epicentral intensity and its scale (European Macroseismic Scale 1992 or 1998, EMS92, EMS98; Geofina; Mercalli, Cancani, Sieberg, MCS; Modified Mercalli, MM; Medvedev, Sponheuer and Karnik 1964, MSK64; Rossi Forel, RF) has been defined, despite of a number of problems associated with the assessment of epicentral intensity.
		The use of a unified magnitude scale in ground motion studies is another important consideration ( Ambraseys and Smit, 1998).
		The intensity-values have been directly adopted from the literature or from bulletins without re-assessment.

	Earthquakes
		In the late nineteenth century, a 10-point scale to measure earthquakes was invented by François-Alphones Forel and Michele Stefano de Rossi, and was in use for a while ("The Story").
		In 1902, Giuseppe Mercalli created a 12-point scale of intensity that measures the strength of shaking produced by the earthquake at a certain location ("The Story").
		Unlike the Mercalli scale, the Richter scale measures the magnitude of an earthquake at its epicenter ("The Story").

	Introduction
		The 1990 Luzon Earthquake was felt in many places at Intensity VIII (based on a modified version of the Rossi-Forel Intensity Scale of I to IX currently used in the Philippines).
		At 4:26 PM of 16 July 1990, Central Luzon was rocked by the strongest quake to hit northern Philippines this century.
		A 125 km long ground rupture was consequently formed along the Gabaldon (Nueva Ecija)-Kayapa (Nueva Vizcaya) segment of the Philippine Fault-Digdig Fault system (Fig.
