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.

Earthquake magnitudes are determined from seismic waves, the ground-bending waves generated by the earthquake fault. The energy in these waves lessens with distance. As you move farther from the earthquake fault, the intensity of the shaking decreases. At a fixed distance from the fault, the larger the earthquake magnitude, the greater the shaking.As a result, seismic waves (also known as S waves) are generated. The seismic activities in an area determine the earthquake’s type and intensity. Scientists measure and record the seismic activities that occur during an earthquake with the help of an instrument known as the Seismograph.Feb 5, 2023 · The earthquake, which hit at 4:17 a.m., according to the United States Geological Survey, measured at magnitude 7.8.
