Three quakes!
Is this the “earthquakes in diverse places” thing?
8 is a bit much.
Sure seems to be a few big ones lately.
I imagine when that happens it will be on and on and on.
Earthquake comparison tool https://earthquake.usgs.gov/learn/topics/how_much_bigger.php
The difference between these two magnitudes is... 1.2
A magnitude 8.0 earthquake
is 15.848 times bigger than
a magnitude 6.8 earthquake,
but it is 63.095 times stronger (energy release).
