Bold type indicates a "Seismic Window" of increased, potential for earthquakes.
Underlined items for quakes within perigean spring tides with Sychroneity less than 37 hrs.
Mg = Magnitude
Int = Mercalli Intensity
Lat = North Latitude
Lon = West Longitude
e = Eclipse (et = Total Eclipse)
FM = Date of Full Moon in relation to Quake
Per = Perigee = Date of Perigee in relation to Quake
NM = Date of New Moon in relation to Quake
