Earthquake magnitude

This is a list of earthquakes in 2023.Only earthquakes of magnitude 6 or above are included, unless they result in significant damage and/or casualties. All dates are listed according to UTC time. The maximum intensities are based on the Modified Mercalli intensity scale.Earthquake magnitudes are based on data from the USGS..

Scientists base the magnitude on the strength and duration of the quake’s seismic waves. The higher the number, the more powerful the earthquake: A magnitude 3 to 4.9 earthquake is considered minor; 5 to 6.9 is moderate to strong; 7 to 7.9 is major; and 8 or more is an extremely powerful temblor.0:47.

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. Neural networks are investigated for predicting the magnitude of the largest seismic event in the following month based on the analysis of eight ...Earthquake - Magnitude, Intensity, Effects: The violence of seismic shaking varies considerably over a single affected area. Because the entire range of observed effects is not capable of simple quantitative definition, the strength of the shaking is commonly estimated by reference to intensity scales that describe the effects in qualitative terms. ….
