Aftershocks and Foreshocks

I found this animation today, along with this article explaining a new development in analyzing the quake data.

The article doesn’t explain exactly what is different or new about this quake, but seems to imply that the foreshocks were foreshadowing the biggest tremor. It’ll be interesting to see if geophysicists can read some sort of pattern for prediction from all the shocks.  The article I posted the other day explained why larger quakes are more difficult to measure than smaller ones. Maybe there’s some sort of threshold for size or saturation, or where they start to behave differently.  That would fit in with how complex systems behave, I think.

I wonder if it fits in with some of my worries that this could be bigger than it is.
