I put together a little display of the earthquake action of the first 4-5 hours after the large event using data from the USGS site. [0] You can follow the action from event to event over the course of the first 22 events (about 4-5 hours I think). [0] https://postimg.cc/HckCRn1m https://postimg.cc/HckCRn1m It started near Hualien City with the magnitude 7.4 and then if you folow the blue lines you can see how it rattled NE-SW mostly along the coast for the first hour (6 events) then following the pink line you can see it popped at the NE end along the coast before a series of events that curved out into the sea to the E-SE for the next hour (5 events). That was followed during the third hour by 4 events oriented roughly NE-SW in green with all but one offshore to the NE. The fourth hour saw 4 more events almost complete the square in yellow. Things were quieting by then and the fifth hour only saw two events, both offshore in light blue with the series ending red with a single event offshore. I have a graph of activity showing the magnitude and depth versus the time of the event. You can see that the later events trend deeper and lower magnitude making them unlikely to be felt as much as the initial event and less likely to cause as much damage.

In the map view you can get a feel for the region's relaxation after the main quake and the other graph allows you to see how the event magnitudes decreased while the later events tended deeper.
