Data for the same earthquake reported by different agencies​

Info: The more agencies report about the same quake and post similar data, the more confidence you can have in the data. It takes normally up to a few hours until earthquake parameters are calculated with near-optimum precision.

I usually don't feel small earthquakes like this (small by Chilean standards) even when the epicenter is close, but because of the depth (114km according to the University of Chile seismology center) is must have been felt over a large geographical area:

Yes, I read that these M5+ earthquakes are a "piece of cake" for what people in Chile are used to. There is even a tweet from a broadcaster who is still working as if nothing happened.
