Kerry E. Sieh is an American geologist and seismologist. (wikipedia)
If nothing ruptured, then that's really good news for the engineers who were trying to make it in fact so that it wouldn't.
This earthquake didn't just break all the records, it also broke some of the rules.
It's not a duplicate. It occurred a little bit further south. But it's the same type of earthquake.
This looks like a fraternal twin of the December 26 earthquake.
