thats kind of relative, seeing as how an earthquake after an earthquake is an aftershock

So is this a new Earthquake or an aftershock?

Any quake in the vicinity of the epicentre of the initial mainshock (the mag 5.8) is deemed an aftershock until activity in the area returns to normal (i.e none in this case!!).
IF a larger earthquake occurs it will be deemed the mainshock and the 5.8 renegated to a foreshock.
