Hope this is not a sign of things to come

Since the Hualien earthquake sequence began, almost all subsequent activity has occurred in a tight cluster around the same area

There was one in Pingdong about a week ago and now one in Taidong near Green Island - but that's it. That in itself is unusual - a normal fortnight in Taiwan you would expect to see small shocks in a range of places across the island

I do expect there to be a significant earthquake triggered somewhere in Taidong as a result of the Hualien failure, and going on past history, we can expect some fore-shocks as a warning salvo. As such, it's a good time to stay alert to the earthquake reports and if a few start popping up in the same vicinity then that would be cause for serious concern

Additionally, it appears a triggered sequence is currently being played out in Mexico - after two big earthquakes from September last year, another 7+ yesterday in a different location
