"The survival value of human intelligence has never been satisfactorily demonstrated." Fictional character Dr. Jeremy Stone in Michael Crichton's novel, The Andromeda Strain.
A major contributor to our situation is over population. A segment on Quirks and Quarks about a year ago said the maximum sustainable human population is 1.5 billion. If we don't reduce our population, mother nature will. The latter option is not a pleasant one.

The world population has been over 1.5 billion for well over a hundred years and we're still here. But I agree adjustments need to be made. One problem is that countries that can afford to have kids aren't, while those that can't, are. Lot's of young people in India, lots of old people in Canada for instance.

wait... what? Given your expressed rejection of all proxies/reconstructions, what are you relying upon to make such an outlandish statement on your 20K years past warming - hey!  ;D
hey member TimG - what's your understood/interpreted attribution for today's relatively recent warming... say from the industrial age on?

Populations under threat ... reproduce.
Forces of nature, more children, more chances some will survive. Also more people to help out?
Not sure why, but ... people in comfortable circumstances do reproduce less.

I learned to withold water and fertilizer from some plants because they only flower under threat.
Made me think ... Lol

That's the conclusion I have found in various studies I have read on population growths, namely that producing children may provide a path to improved living conditions. And actually when I pause and think back on a personal level, my grandparents emigrated here from Scotland in around 1910. They were young and poor but they knew how to farm, which they did for others until they earned enough for a down payment on a chunk of land of their own. Then they also set about having six children and luckily it all worked out very well. Just checked and the average fertility rate in Canada now is 1.6 per woman.

More affluence, less children. Go figure.

And the pill ... only available since the '60's.
Made a HUGE difference. Lol

A whole lotta shakin' goin' on in southern Cal. and surrounding area. A 6.4 occurring and the seismic folks are expecting a number of after shocks and possibly an even bigger shock coming up. I wonder if Trump arranged this to help celebrate the 4th.

Looks like a whole lot of soup cans to put back on grocery store shelves from the pics I'm seeing.

I have spent a lot of time in California, but never "experienced" one there. I am sure in all the time I was there, that there were many tremors I could have felt if I was paying attention. I guess when you are away for work, other things occupy your attention that you don't get any quiet time to feel what is happening. I have however experience 3 in Ontario. In all cases I was alone in a quiet place and could tell that something happened. One was centered in Cincinnati, and the other two were in Quebec. Being several hundred miles from them, the effect was subtle but noticeable. In one case I was outdoors at the time and could feel the ground trembling, I had been working hard with a pick-axe and shovel for a few hours so my first thought was did I overdo it.

I have experienced a couple over the years. One of the scariest was in Haiti. I was just getting settled into my hotel room in a suburb of Port aux Prince called Petionville which is high up on a ridge south of the city. The ridge drops off again and the south side of the hotel is supported by brick pylons. When things started to shake I immediately envisioned those pylons crumbling and the whole place sliding down the hill. I raced for the door as apparently everyone else in the place did and we were now all standing by the swimming pool watching the waves slap against the sides. The building survived fine it seemed and so after a couple of sips around the pool it was bed time and so everybody drifted back inside but I doubt many of us had a really sound sleep.

A few shakers but nothing serious. A couple in Japan, one in Alaska and one of the Seattle quakes which was also felt in Vancouver back in the sixties and of course Mt. St Helens which was more heard than felt. Pretty unnerving One really mild one in the nineties that had my daughter freaking out. She was in the bathtub and the water started slopping around.

A couple shakes out here on the coast. 5 or so tsunami alerts however from quakes elsewhere around the Pacific.  Only the April 2011 Fukushima earthquake produced results we could actually see. I was tied to the dock working on the boat that day and we saw the tide come and go 3 times in the space of an hour or so.  A buddy and I went jigging ling-cod on one warning/occasion but that was years before we had any brains and the evidence of Indonesia and Fukushima to sober our thinking.  That said I've seen people flee to local mountain tops during warnings so there's more than one sort of brainlessness that can exist in the face of these things.  The last warning there was a lot of warning sirens, mobilizing and evacuating going on. Some predictably high-tailed it to much higher-ground than the recommended 30 meters.  Despite our even higher elevation our neighbour's teenager and a few others around me basically started hiking or driving up the mountain behind us on old logging roads.  That seems unsafe to me, If they get themselves into some other sort of jam I suspect any help they might need won't be available because emergency services will be running around doing other things.

I don't dwell on it but its sort of at the back of mind now and then when I'm up some long narrow inlet miles from the open sea and deeper water I'd probably rather be during the Big One.  We'll only have 15 minutes or so to get to higher ground or deeper water as the case may be.

The strongest one I experienced was Jalalabad Afghanistan. Again I had pretty much just arrived there so I was wondering if it was my presence that caused these things to occur. I wasn't too afraid as I was in a single story building constructed basically of nailed together 2x4's and plywood and they can stand up to a shake or two. The worst part was that it seemed like the shaking went on forever. It was a 6.9 according to Mr. Richter and it probably actually lasted about 20 seconds. A sea of water bottles had flown off shelves and a few laptops ended up on the floor, but the building held up. The US military had just moved into a brand new control tower they had built at the airport. It stayed standing but you could see a lot of cracks in the concrete. I love boating but that tsunami thing scares the hell out of me.

Big ones 9.0+ happen on the Cascadian subduction zone on an average of every 400 years. It is 319 years since the last one.

Well then I hope everything sticks to the schedule and I'll be able to experience the next big one from my own "subduction zone".
