The Richter scale measures the magnitude of an earthquake (how powerful it is). It is measured using a machine called a seismometer which produces a seismograph. A …The highest-magnitude earthquake on the Richter scale took place in Chile in 1960. It came in at 9.5 on the Richter scale, killing almost 1,700 people and injuring 3,000 more.The Richter scale is a base-10 logarithmic scale, meaning that each order of magnitude is 10 times more intensive than the last one. In other words, a two is 10 times more intense than a one and a three is 100 times greater. In the case of the Richter scale, the increase is in wave amplitude. That is, the wave amplitude in a level 6 earthquake ...Plug magnitude values of 5.0, 6.0, and 7.0 into the equation above. The energy released by an M5 earthquake is about 2.8 x 10 12 joules. An M6 earthquake releases 7.8 x 10 13 joules, and an M7 radiates 2.1 x 10 15 joules. If you don't have a sense for what these numbers mean, the bomb dropped on Hiroshima released about 7.4 x 10 12 joules.ANNUAL EARTHQUAKES. In a single year, on average, more than 900,000 earthquakes are recorded and 150,000 of them are strong enough to be felt. Each year about 18 earthquakes are major with a Richter magnitude of 7.0 to 7.9, and on average one earthquake has a magnitude of 8 to 8.9. Magnitude 9 earthquakes are rare.Whenever we hear of an earthquake, its magnitude is always explained in terms of the Richter scale. For instance, the one that hit Haiti in 2010, measured 7.0 on this scale. This figure is calculated on the basis of the tremors caused at that time, as well as the energy that was released by the tremors. Beno Gutenberg and Charles F. Richter, both of whom were American seismologists in the year 1935, created it. The magnitude of an earthquake is measured by determining the height of the biggest seismic wave shown on a scale by a seismograph. With the continued technological evolution, improved scientific practices have replaced …The Richter scale, developed in the 1930s, is a base-10 logarithmic scale used to quantify the magnitude of an Earthquake.

On the Richter scale, the magnitude of an earthquake is related to the released energy E in joules (J) by the equation. log 10 E = 4.4 + 1.5M. The 1906 San Francisco earthquake registered 8.2 on the Richter scale. Using the above equation, the released energy was E = 5.011872336x10 16 JA magnitude 4.0 earthquake is only equivalent to about 15 tons of TNT explosives, but because the Richter scale is a base-10 logarithmic scale, the amount of energy released increases quickly. A magnitude 5.0 earthquake is about 480 Tons of TNT tons of TNT, magnitude 6.0 is 15080 tons,Richter Scale. Magnitude is the measure of the energy released by an earthquake. The Richter scale (M L), the first and most well-known magnitude scale, was developed by Charles F.

(In fact the scale itself does not set an upper or lower limit; limits of earthquake size are set by the Earth). Moment MagnitudeWhat does a minor or light earthquake mean? The Richter magnitude scale is a measure of the strength of earthquakes, which can also be used to qualitatively describe the strength of a quake based on the quantitative number. Magnitude: Qualitative Description: Mercalli Intensity: 1.0 – 1.9: Micro: I: 2.0 – 3.9: Minor: I – IV:EARTHQUAKES The Richter Scale.
