"Scientist John Cassidy says the two quakes in the same place in such a short time is a coincidence."
" 'It's a little bit unusual to have two earthquakes of that size so close together in time but this is a very active region.' "
It's interesting that they didn't label the first one a foreshock instead of a "coincidence."
That's what seismologists tend to report down here. Often it seems, if the 2nd quake is slightly smaller, they call the second earthquake an "aftershock."
The word "coincidence" makes the "events" sound a little less serious, though it's unclear that that would be a seismologist's or geologist's motivation.
Odd.
After any 5+ magnitude quake, is rare NOT to have aftershocks!
So what is this scientist referring to by claiming a "coincidence" of two earthquakes in the same area?
