In most cases there is an initial report within 10 to 30 minutes of all magnitude 5.0+ earthquakes globally, and magnitude 4.0+ earthquakes within the contiguous U.S. Note that the magnitudes and locations in the initial reports are only first-order approximations, which get revised in the following hours, days, and months.

The United States typically has around 63 earthquakes between magnitude 5.0 and 5.9 each year, according to the U.S. Geological Survey, about five between 6.0 and 6.9 and fewer than one between 7. ...
The Richter scale [1] (/ ˈ r ɪ k t ər /), also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale, [2] is a measure of the strength of earthquakes, developed by Charles Richter in collaboration with Beno Gutenberg, and presented in Richter's landmark 1935 paper, where he called it the "magnitude scale". [3]
Originally intended for estimating the magnitude of historic earthquakes where seismic data is lacking but tidal data exist, the correlation can be reversed to predict tidal height from earthquake magnitude. [63] (Not to be confused with the height of a tidal wave, or run-up, which is an intensity effect controlled by local topography.) Under ...
The magnitude of an earthquake isn't enough to determine how much death and destruction it will cause. Location, time of day, building codes and other factors make a big difference.
Aftershocks can be distinguished in part by starting immediately following a main shock, but usually about 1.2 magnitude smaller, and rapidly decaying in magnitude and frequency (see Bath's Law, whereas doublet/multiplet events are usually only a few events of roughly the same magnitude, separated by hours, days, or even weeks.
