Magnitude measures the former, while intensity measures the latter.11 Des 2018 ... Seismographs are able to measure the time, location and strength of an earthquake. The earthquake magnitude communicates its energy level, ...Therefore, the greater the magnitude, the more energy is released during the earthquake. Following this logic, this would be a logarithmic scale. Put another way, the increase in magnitude of 1 unit would correspond to the increase in energy release of 30 units. And it is based on this theory that the Richter Scale arises.The intensity scale consists of a series of certain key responses such as people awakening, movement of furniture, damage to chimneys, and finally - total destruction. Although numerous intensity 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 first earthquake was big - it registered as 7.8, classified as "major" on the official magnitude scale. It broke along about 100km (62 miles) of fault line, causing serious damage to buildings ...Measuring an earthquake’s intensity. The intensity of an earthquake is measured using the Modified Mercalli Intensity, or MMI, Scale. It measures the strength of an earthquake’s shaking at specific locations around its epicenter – the spot on Earth’s surface directly above a quake’s underground origin. The MMI scale uses Roman ...Fast Fact: Measuring Earthquakes. Earthquakes are measured by special machines called seismometers. Scientists use the numbers from 1 to 10 to say how strong an earthquake is. This number system is called a scale, or a magnitude scale. Magnitude means how big or strong something is. Higher numbers mean stronger earthquakes.The Mw scale is a more accurate measure of the magnitude of large earthquakes than other scales, such as the Richter scale. This is because the Richter scale is based on the amplitude of seismic waves, which can be affected by the distance to the earthquake and the type of ground that the waves travel through.An earthquake measuring 6.9 on the Richter scale devastates north-west Armenia, killing 25,000 people. 19 September 1985 Mexico City is shaken by a huge earthquake which razes buildings and kills ...The calculation of earthquake size using this scale is based on earthquake seismic movement rather than the amplitude of seismic waves recorded by a seismograph.
