Seismic moment is a quantity used by seismologists to measure the size of an earthquake. The scalar seismic moment M 0 {\displaystyle M_{0}} is defined

minor seismicity, in a brick building located on fill subject to liquefaction can be as high or higher risk. A special subset is urban seismic risk which

Southern California Seismic Network uses this "magnitude" where the data fail the quality criteria. A special case is the Seismicity of the Earth catalog

oceanographers. The term seismic sea wave is also used to refer to the phenomenon because the waves most often are generated by seismic activity such as earthquakes

In seismology, a seismic zone or seismic belt is an area of seismicity potentially sharing a common cause. It can be referred to as an earthquake belt
