In many ways, the intensity is an even more important measure of an earthquake as it is related to the tangible impact a quake has. Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location.It does not have a mathematical basis; instead it is an arbitrary ranking based on observed effects. The Modified Mercalli Intensity value assigned to a specific site after an earthquake has a more meaningful measure of severity to the nonscientist than the magnitude because intensity refers to the effects actually experienced at that place.... did not rupture, but the ... The magnitude of an earthquake is based on measurements from instruments, so it is objective. Intensity is a subjective measure.Geology. The intensity is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth’s surface and on humans and their structures. Several scales exist, but the ones most commonly used in the United States are the Modified Mercalli scale and the Rossi-Forel scale.Earthquake intensity measures (IMs) are fundamental for describing the important characteristics of ground motion in a quantitative manner. Many IMs have been proposed to characterize the amplitude, frequency content, and duration of motions (Kramer, 1996).Since intensity is a measure of earthquake shaking, it is important that scale diagnostics are effects that actually relate to shaking, such as the movement of objects and damage to buildings. Objects, buildings, and people make reliable sensors for deducing intensity; the natural environment does not provide good sensors.The Richter scale is a scale of numbers used to tell the power (or magnitude) of earthquakes. Charles Richter developed the Richter Scale in 1935. His scale worked like a seismogram, measured by a particular type of seismometer at a distance of 100 kilometers (62 mi) from the earthquake. Earthquakes 4.5 or higher on the Richter scale can be ... The intensity of an earthquake is not entirely determined by its magnitude.and the Rossi-Forel scale,measure theamount of shaking at a particular location. An earthquake causes many different intensities of shaking in the area of the epicenter where it occurs.

Based on damage from ...Intensities a measure of the amount of ground shaking at a given location. Intensity not magnitude measures how about the earthquake is a location. Most common measurement of intensity is a modified Mercalli scale. Mercalli scale. Modified Mercalli is a good qualitative description of intensity in terms of damage levels. a break or fracture in a rock mass across which movement has occurred. focus (hypocenter): the point of origin of an earthquake. any of various instruments for measuring and recording the vibrations of earthquakes. massive irregularly-shaped sections of Earth’s crust that are constantly in motion. Most earthquakes are caused by the movement ...To locate an earthquake epicenter: 1. Scientists first determine the epicenter distance from three different seismographs. The longer the time between the arrival of the P-wave and S-wave, the farther away is the epicenter. So the difference in the P and S wave arrival times determines the distance between the epicenter and a seismometer. The Modified Mercalli Scale of Earthquake Intensity In seismology a scale of seismic intensity is a way of measuring or rating the effects of an earthquake at different sites. …Prior to the development of the magnitude scale, the only measure of an earthquake's strength or "size" was a subjective assessment of the intensity of shaking observed near the epicenter of the earthquake, categorized by various seismic intensity scales such as the Rossi-Forel scale.
