檢視所有 Wikipediahttps://en.wikipedia.org/wiki/Moment_magnitude_scaleThe formula above made it much easier to estimate the energy-based magnitude M w , but it changed the fundamental nature of the scale into a moment magnitude scale. USGS seismologist Thomas C. Hanks noted that Kanamori's M w scale was very similar to a relationship between M L and M 0 … 查看更多內容
The moment magnitude scale (MMS; denoted explicitly with Mw or Mw, and generally implied with use of a single M for magnitude ) is a measure of an earthquake's magnitude ("size" or strength) based on its 查看更多內容
Moment magnitude is now the most common measure of earthquake size for medium to large earthquake magnitudes, but in practice, … 查看更多內容
Seismic moment is not a direct measure of energy changes during an earthquake. The relations between seismic moment and the energies involved in an earthquake depend on parameters that have large uncertainties and that may vary between … 查看更多內容
Various ways of determining moment magnitude have been developed, and several subtypes of the Mw scale can be used to indicate the basis used.

At the beginning of the twentieth century, very little was known about how earthquakes happen, how seismic waves are generated and propagate through the earth's crust, … 查看更多內容The symbol for the moment magnitude scale is Mw , with the subscript "w" meaning mechanical work accomplished. The moment magnitude Mw is a dimensionless value 查看更多內容
Assuming the values of σ̄/μ are the same for all earthquakes, one can consider Mw as a measure of the potential energy change ΔW caused by earthquakes. Similarly, if one assumes $${\displaystyle \eta _{R}\Delta \sigma _{s}/2\mu }$$ is the same for all … 查看更多內容
