No I am not comparing apples to oranges. Stress is stress no matter how it is built up. There is movement and it may not be subduction, or maybe it is, and movement is what causes the stress. Sorry but you cannot get away from that. No movement, no stress.
So tell me where in the middle of Asia? No matter where you pick you will find plate movement causing stress, or Coriolis movements causing stresses in or rather under apparent solid land masses.
The simple facts are that once an area, and it matters not which area, looses its built up stress it goes right back to building it up again. That takes time. In my opinion there are insufficient forces at work in the NMSZ to produce a mag 7.5 to 8 for many decades - possibly 200 years yet.

I had a working theory that the quartz crystals may resonate as an amplifier. Maybe explaining why the effects of a quake here in Arkansas (with Huge amounts of Quartz crystals) are so widespread even quite a distance from the epicenter.
There is so much to learn about all of this !

I have a few rather beautiful quartz crystals from Arkansas (amongst other places), and I too have often wondered about their resonance and amplification abilities in relation to EQ's. I just wish I could find the link to a recent scientific study that was recently undertaken whose results showed a very strong possibility that they indeed do this (as do other minerals but not to the same degree).
Within this paper which was written by a group of geologists from some university or institute, they also found quartz ceystals recorded previous seismic events.....I had to smile at this finding as there is a certain configuration of quartz known as a record keeper!
It is late, but I shall try and trace the article from my old emails and post the link here tomorrow.
PS...unless somebody else beats me to it overnight!
SAN DIEGO—The Scripps Institution of Oceanography has been awarded a $1 million grant to develop a deep sea seismic network.
Scientists hope this new system will plug current monitoring gaps.
Ships typically deploy earthquake sensors in the ocean that gather data for a certain amount of time before they are retrieved by vessels.
Scripps will pair with industry in the project that's being funded by the National Science Foundation. Data from the sea floor sensors will be transmitted to a surfboard-sized autonomous unmanned vessel on the ocean's surface, and then to shore via satellite.
Researchers say the unmanned vessel would be able to stay stationary for longer periods of time, allowing for more data collection.

Tracked the reference for that.

as the universe is expanding
Time appears/or may appear to speed up. So time as we appear to experience it is becoming shorter. What we acheived in 100 years is now reduced to achieving greater things in 10 years.
Maybe the planetery experience is speeding up and what you envisage could be a lot closer than your estimations?
