# How To Which scale measures the amount of damage after an earthquake: 9 Strategies That Work

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. Here is a photograph of Giuseppe Mercalli, the inventor of the Mercalli ... Recently, scientists have begun to use the more precise moment magnitude scale, which measures the total energy released by a quake. The moment-magnitude scale is logarithmic, so an increase of one unit means an earthquake is 10 times bigger, with about 30 times the energy produced.Richter scale Classification of earthquake magnitude set up in 1935 by the US geologist Charles Richter (1900–85). The scale is logarithmic – each point on the scale increases by a factor of ten – and is based on the total energy released by an earthquake, as opposed to a scale of intensity that measures the damage inflicted at a ...Terms in this set (14) The point at which an earthquake originates is the ____________ .

The place where the greatest damage occurs. The point on the surface directly above the focus. Multiple Choice.Below are five steps to take after an earthquake occurs. One of the first steps you should take after an earthquake is to check the gas and water lines to your home. As a precaution, you may want to turn them off for a few hours. Then you can turn them back on when you know the area is secure, and that nothing is wrong with gas or water coming ...How Are Earthquakes Measured? Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary movement of the ground. Magnitude measures the former, while intensity measures the latter.11.3 Measuring Earthquakes. There are two main ways to measure earthquakes. The first of these is an estimate of the energy released, and the value is referred to as magnitude. This is the number that is typically used by the press when a big earthquake happens. It is often referred to as “Richter magnitude,” but that is a misnomer, and it ...The two types of seismic waves described in “Plate Tectonics,” P-waves and S-waves, are known as body waves because they move through the solid body of the Earth. P-waves travel through solids, liquids, and gases. S-waves only move through solids. Surface waves travel along the ground, outward from an earthquake’s epicenter.Intensity is based on the observed effects of ground shaking on people, buildings, and natural features. It varies from place to place within the disturbed region depending on the location of the observer with respect to the earthquake epicenter. Magnitude is related to the amount of seismic energy released at the hypocenter of the earthquake.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 how …... scale, measure the amount of shaking at a particular location. The Modified Mercalli Scale ranks earthquake intensity on a scale of I. (not felt) to XII ...The Richter Scale measures the magnitude or amount of energy released by the earthquake. This is a measure of size for earthquakes based on recordings of ground motions by instruments. Charles Richter developed the first magnitude scale in 1935. He used the logarithmic scale (which scales numbers by a factor of 10) to accommodate the …Earthquake size, as measured by the Richter Scale is a well known, but not well understood, concept.
