No worries, violet. Quite often we see reports coming in of two quakes when there's only one. Or an agency says it's such-and-such a magnitude and another has it a few points higher or lower. It can get pretty confusing.

And then there's the teleseisms which can result in a quake getting reported in a place that didn't really have one: some localized seismos picked up one from many miles away but the software calculated it as local. (These errors usually get deleted pretty quickly once they're review by a seismologist.)

Big quakes can really confuse things. After the huge Japan quake in March last year, the Pacific Northwest Seismic Network's VLA got so swamped by the aftershocks for a few days that their local data from ETS episodes was practically impossible to read and they simply had to scrap it.

So, whenever we get conflicting or multiple-quake reports coming in, it's best to wait a little while until the various agencies figure out what their auto-detectors are really picking up. Then, once they've sorted it all out and done their revisions, things tend to make sense.

Usually!
