The Eurasian Plate is moving. It is translating into movement along the Arabian Plate, Australlian Plate and nudged the Pacific plate north against the North American plate.
Wrong the pivot point is Dushanzi, China. The Eurasian Plate is rotating clockwise. The North American Plate is being squeezed against the Pacific Plate. That is why the Alaskan islands are receiving seismic activity. The pressure is coming from the north.
There was a 4.5 in that Chinese province today, but, there was also a 4.7 on June 24, 2013. There are two geological faults that effect the stability of the region. (click here)
The faults are in the Paleozoic (Palaeozic in Chinese). The province is primarily in the Quaternary. The Paleozoic is the primary 'base' of the country. There are some outcrops of older rock, Precambrian.
It makes sense that Dushanzi is a region that would rotate. It has consistent aged rock that would provide a strong adherence to movement of the plate. In other words, the base rock is throughout without reason to distribute the stress into other younger formations.The outcrops of the oldest rock on Earth only provides a deeper view of the Eurasian Plate's stability and moving as one 'piece' of land.
The Chinese have a lot of dangerous earthquakes. There may be a sincere reason beyond simply mountain formation.
The Chinese love their long lived heritage from the beginning of time. It would be an interesting investment into understanding Chinese earthquakes to also find some fascinating prehistoric artifacts.
I did a study of the coastal region and found a very small and distant culture known as Qingliangang. It was a very unappreciated culture. It failed because of sea level rise and the loss of their rice capacity. The flooding fragmented the culture too much to sustain it's longevity.
A really interesting fact came out about the relationship between China and Japan while I was researching the Qingliangang culture. The same species of rice was found in Japan that this culture existed on. It raised the question that when ice ages occurred was there enough land mass between China and Japan to allow migration. That question is still open.
The rice was found in Neolithic pottery. Really cool stuff. They were a great culture. They appreciated beauty and used artistic technique in their pottery. They were sophisticated. A very brief culture in the history of China. I liked them a great deal.
But, any investment to understand Chinese earthquakes could also unearth some interesting return on the investment.
I have no interest in the funding or the research. There are very talented Chinese archeologists and anthropologists. I am sure they would love to chase any and all of that down.

The European-Mediterranean Seismological Center (click here) reported that the
earthquake whose epicenter was in Amfiklia, a town in the Phthiotis
regional unit, had a magnitude of 5.2 on the Richter scale.
According to the same source, the focal depth of the quake was 10 kilometers and took place 116 kilometers away from Athens.
The residents of the region, who in the last months have often been
feeling the earth moving under their feet, are quite alarmed. Fire
Brigade men are already out in the streets in case anyone needs help.
A little earlier, at 17:49 in the afternoon, a 4.6 magnitude tremor
jolted the region, too, according to the Athens Institute of
Geodynamics. Again the epicenter of the quake was in Amfiklia, 23
kilometers southwest of Atalanti, a town in southeastern Phthiotis,
Greece.

Georgia, Tbilisi, Sept. 17 / Trend N. Kirtzkhalia /
A strong earthquake occurred in Georgia on Tuesday morning. According
to the Seismological Monitoring Centre at the University of Elijah, it
was a 5.3 magnitude quake in Kvareli (Kakheti, eastern Georgia).
The epicentre was a few kilometres from Kvareli. The earthquake occurred at 8:08 a.m.
There was no information about any damage or casualties. Tremors were felt in Azerbaijan near the border.
