The Richter Scale measures earthquakes by using seven different categories: micro, minor, light, moderate, strong, major, and great. Below is a look at each description: Micro earthquakes are measured at between 1 and 1.9. This magnitude would be considered a I on the Mercalli intensity scale. These earthquakes are not noticed by the general ...The Richter magnitude scale is used to measure the size of earthquakes. The higher the number, the more powerful the earthquake and the higher the chance that it will cause …The formula for the Richter magnitude, M, of an earthquake is M = log ⁡ A A 0 M=\log \frac{A}{A_{0}} M = lo g A 0 A , where A is the amplitude of the ground motion and A 0 is the amplitude of a standard earthquake. In 1985, an earthquake with magnitude 6.9 on the Richter scale was recorded in the Nahanni region of the Northwest Territories.The moment magnitude of an earthquake is a measure of the amount of energy released - an amount that can be estimated from seismograph readings. The intensity , as expressed by the Modified Mercalli Scale , is a subjective measure that describes how strong a shock was felt at a particular location. Best Answer. Copy. The Mercalli scale, which measures the visible effects; and the Richter scale, which measures the energy given off by the earthquake, are the two most common ways of measuring ...The digital recording is called a seismogram. A network of worldwide seismographs detects and measures the strength and duration of the earthquake's waves.

For example, hurricanes are measured by category (1-5) based on wind speed. Tornadoes are measured on the Fujita scale (F1-F5) estimated by damage that is caused. Earthquakes are measured by magnitude (1-10) based on the energy released. Earthquakes occur when tectonic plates slip. This shift causes the earth to shake.One of the major advances in the development of magnitude scales was the concept of ‘seismic moment’ (Kanamori, 1978).The Seismic Moment is considered to be the most accurate and comparable measure of an earthquake and can be considered as a measure of the irreversible inelastic deformation in the fault rupture area (Kanamori, 1977).The magnitude of an earthquake is commonly measured using the Richter scale or the moment magnitude scale.

M = 32 log 0.007E where E is measured in kilowath-hours. a.Relation between Magnitude, Energy and Intensity. If the earthquakes would occur at only one, say shallow, focal depth, the maximum seismic intensity at the surface could serve as a rating of the strength of the given earthquake, provided the ground conditions were similar at all observational sites. The Richter Scale is a scale that is used to measure the magnitude of earthquakes, and was first developed by Charles Richter in 1935. It is a logarithmic scale starting at 1, which represents the smallest earthquake that can be felt, with each increase in integer representing a ten-fold increase in earthquake magnitude.I - XII (ROMAN NUMERALS) Who was Charles Richter? a SEISMOLOGIST who created the scaled to measure an earthquake's magnitude.

The other is based on intensity—how much the ground shakes at a specific location.How is the magnitude of an earthquake determined? Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at that site. The slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate.What is used to describe earthquake magnitude?
