As a result, USGS partners including FEMA's Wireless Emergency Alert system ...How Are Earthquakes Measured? Two different viewpoints underpin the most important measurements related to earthquakes: magnitude and intensity. To scientists, an earthquake is an event inside the earth. To the rest of us, it is an extraordinary movement of the ground. Magnitude measures the former, while intensity measures the latter. There may be errors in the antenna heights. The velocities are very dependent on the length of the span of observations. The presence of outliers (errant observations) sometimes contaminates the velocities. « Back to BasinAndRange_SGPS_ITRF2014 Network.

The first earthquake magnitude scale was invented by Charles Richter for southern California in 1935. Unlike seismic intensity, which measures the strength of shaking and varies according to distance from the quake and other factors, the magnitude is intended to measure the intrinsic size of an earthquake.Earthquake - Magnitude, Seismology, Epicenter: Earthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the section Seismic waves.) Because the size of earthquakes varies enormously, it is necessary for purposes of comparison to compress the range ... A round, or multiple-sided home, is more resistant to hurricane strength winds.
