Earthquake Cluster in Hualien (General)
Hualien does get a lot of relatively small earthquakes, i know, but this seems extreme.
14 earthquakes in a period of a couple of hours! I'd be feeling jittery if i was living on top of them.
There was a 5.7 (?) earthquake in Ilan a few days ago, so they may be aftershocks from that and it's all 'perfectly normal', but ... 14 in 2 and a bit hours!
