It is currently being conducted and the adequacy of the ground motion.
Each point on the scale indicates a tenfold increase in ground motion.
Most instruments measure directly the ground motion using the distance sensor.
Its size was measured as 7.8 on the Richter scale of ground motion.
A certain ground motion has an x percent probability of being exceeded in Y years.
Regional geology can have a large effect on the characteristics of ground motion.
The Richter scale is based on ground motion recorded at a distance.
The methods explained here concern only losses due to strong ground motions.
Besides air pressure, tactile sound can be conducted through ground motion.
Also the effects of strong ground motion make it very difficult to record information close to a nucleation zone.
