Yes, that looks very similar! (I assume there are also associated smaller quakes that don't appear on the graphic)

And close enough to Guam to be causing concern there

I'd never heard of the term 'earthquake swarm' until I started doing some background reading for the Hualien quakes but seems it's not that uncommon

I know about the earth slowing this year - and it definitely feels like there are more earthquakes happening - but actually I don't know for a fact - do you?

If the 6.4 is to be taken as the peak event for the Hualien swarm, there were, according to a table I saw, roughly 100 pre-shocks and 300 aftershocks combining for 400 earthquakes in a 5 day period - that's a helluva a lot of activity
