	Earthquake Alert - Important Within this there are the two different meanings of ‘Alert’ and ‘Order’. The ‘Earthquake Alert’ is a warning that ‘in the next 2 to 3 days (or in a few hours even) an earthquake of a magnitude of 8 (the Tokai Earthquake) will strike and the whole of Shizuoka Prefecture will experience tremors of the magnitude of a weak 6’.
