Here is what it looked like on the seismometer I watch in Utah. Look at 1517 UT (right side). All the waves following the EQ are echos. The earth rang like a bell for an hour after the EQ.
Takes time to analyze a strong quake. Especially one in a remote area.
I agree. I just wanted to point out that there was only one EQ of this magnitude in that area, and it was y-day morning.
This was a great post, especially since they raised the mag estimate.
