Although earthquake magnitude is one factor that affects tsunami generation, there are other important factors to consider. The earthquake must be a shallow marine event that displaces the seafloor.
PAGER stands for the Prompt Assessment of Global Earthqu
Although both are sea waves, a tsunami and a tidal wave are two different and unrelated phenomena. A tidal wave is the wave motion of the tides.

It is possible that you have found a bug. The only known bug affects dragging the rectangle in Firefox. If you think your issue is a bug in our code, please let us know.
Currently, PAGER results are not directly available to the public through e-mail. However, users can sign up for earthquake alerts through the USGS Earthquake Notification Service (ENS).
The earliest reference we have to unusual animal behavior prior to a significant earthquake is from Greece in 373 BC. Rats, weasels, snakes, and centipedes reportedly left their homes and headed for safety several days before a destructive earthquake.
The results of past calculations are stored in a table near the bottom of the page. Subsequent calculations will be appended to this table until you reload or leave the page. 
Currently, there are no methods available to do this. Evidence from some case histories suggests that the magnitude of the largest earthquake tends to increase as the total volume of injected wastewater increases.
