Aftershock. 7.2 first one was 8.8.
This might be a dumb question, but how do they differentiate an "aftershock" from an "earthquake?" At what point would it be considered a separate earthquake from the first, rather than an aftershock?
The 8.8 hit off of Conception. Unless I’m mistaken, this one hit in a different part of the fault. If so, then it’s not an aftershock.
