Started at 3.30 this morning with twin 4+ quakes a minute apart, then a 3+ at 8.36pm, then a 5.1 just 36 minutes later. The 3+ was slightly further north, but the others were in almost the exact same location in northern Hualien. All of them relatively shallow

This is a very similar pattern to what happened here - a building sequence - no doubt anyone sitting on top of these quakes today is starting to feel pretty damn nervous and wondering where it's all going
