California earthquakes

Having grown up in California, I experienced many earthquakes.
The first one I remember was the 7.5 magnitude quake in Kern county in 1952.  (I realize I'm dating myself here.)  I was too young to realize what was happening, but I was playing in our back yard at the time and remember seeing the fence sway.  I thought it was something strange.  It wasn't until that night that I learned it was an earthquake - not that it meant anything to me at the time.  We were a hundred miles or so away from the epicenter, and didn't have any damage.
I experienced several more small to moderate quakes over the years in Los Angeles.  Then experiencing the 6.6 San Fernando quake in 1971, when I lived only miles from the epicenter, was quite a shock - in multiple senses of the word.
I had just awakened to my alarm to get up for school when it hit.  I was still in bed.  I thought the building I was in was going to come down on top of me.  Fortunately, it didn't.
A few months after that, I had a brief dream.  I still remember that dream today.  I was down near the coast when a tremendous earthquake hit.  Suddenly, after the shaking, I was about 25 feet under water, with broken-up freeway concrete all around, trying to get up to the surface. 
I don't know whether that dream was due to a holdover stress/emotion (PTSD in today's terms) from the San Fernando quake or something else.
Earthquakes are difficult if not impossible to predict.  At the time, if I remember correctly, someone predicted a high probability of a major earthquake on the San Andreas fault within the next 30 years.  We're now 40-some years later.  It obviously hasn't happened.
My schooling and work took me away from Southern California.
But ever since then, I've tracked earthquakes around the world.  Today, I try to check the USGS site for US and world earthquakes occasionally.  I've noticed the quake numbers increase in the midwest US around Oklahoma.

So to the reason for this post. 
In tracking earthquakes, I've also noticed a couple of other things.
I wonder ...

First, there is a large gap along the western coast of North America in recent (i.e. last 100 years or so) great earthquakes (magnitude 8,0 or above).  There have been great earthquakes in this region in the past.
You may have heard of the "Ring of Fire" around the Pacific Ocean.  It's a roughly horseshoe-shaped feature surrounding much of the ocean where the earth is very active - lots of volcanoes and other geological activity.
Several great earthquakes have occurred around this ring since 1900: 
- Chile (9.5, 8.8, 8.5, and just recently an 8.3)
- Ecuador (8.8)
- Indonesia, with the 2004 quake which killed an estimated 250,000 people from that and the tsunami (9.1, 8.6, 8.5)
- Japan with the 2011 quake which resulted in the tsunami still discussed today because of the Fukushima nuclear plant destruction (9.0)
- Kamchatka and the Kuril Islands, north of Japan (9.0, 8.5)
- The Aleutian Islands (8.7, 8.6)
- Alaska with the 1964 quake and tsunami (9.2).
But there is that gap at North America.

Second, the number of earthquakes greater than magnitude 2.5 in Southern California around the San Andreas Fault, especially near the Salton Sea, seems to have slowed over the last few weeks - at least by my observations.  For several weeks now, the little dots which appear around there to the Mexican border seem less numerous. (Link is http://earthquake.usgs.gov/earthquakes/map/ for the current date if you want to check.)
Now one geological hypothesis is that smaller quakes can relieve the strain so bigger ones don't occur.  I saw a recent news report where that lower section of the San Andreas Fault has not slipped in a major way since the 1600s.
To the right I've inserted two weeks of earthquake data points. The first for the week preceding 9-12-2015; the second for the week preceding 9-25-2015.  (Unfortunately, I don't have images of earlier data showing the higher point count.)

Is this recent reduction of quakes in this section a precursor to the "big one" in Southern California?
And recently there was another prediction that there was a high probability of a major San Andreas quake within the next 30 years.  So what else is new?
Only time will tell.
But I wonder ...

About This Meditation Thing

(Sorry.  No picture this time)
Have you ever tried to meditate?
Were you successful?
I've tried it many times with many different sources over the years - starting with reading how-to books and following what they tell you to do, listening to tapes/CDs, participating in groups with a leader, or whatever.
It has never worked for me.
I don't think I have a Type A overall personality, but apparently I have a Type A mind/brain.  I can't get it to shut off for more than about 15-20 seconds.  It always goes to something that needs to be done ... something I'm concerned about ... something else I would like to do,  etc. 
If I am able to relax some, I'll occasionally go to sleep, especially in the afternoon or any time if I haven't had a good night's sleep.  Occasionally, but rarely, some good may come from this effort.  I'll get an idea for a story, a thought to include in my next project or email, or even an idea for this blog.
When I'm listening to a "leader" - whether in person, on the web, or on a CD, one thing really annoys and frustrates me.
It's the breath cycle timing. 
The leader gets you started by telling you when to breathe in and out.  That's okay.
But a problem appears after that.
He/she then goes off talking about something other than breathing in and out - the benefits of meditation, plant a suggestion, or something - while you are supposed to keep doing the breathe in and out thing.
When he/she comes back and resumes telling me to breathe in or breathe out, I'm almost always out of synch.
If he/she says "breath in" ... well, I may have just finished breathing in and I can't take any more air in.  I need to breath out or my lungs feel like they will explode.  Or he/she says "breath out" when I've just done that and need air.  Am I supposed to breathe out more and begin coughing like the lung capacity tests make me do?
I thought meditation was supposed to be relaxing.
It's amazing how often I come up out of sync with the leader.  It totally destroys any "mood" I did have when that happens.  I feel like I've just wasted my time thus far.  I might as well start again from the beginning on my own, burn my 15-20 seconds, then forget about it.
Even if he/she stays with the breathe in and out cycle, it's often in his/her or some other unknown timing.  And that rhythm may not be my natural rhythm.
Not a very relaxing situation conducive to meditation you think?  It's really frustrating for me.

Anyone else have these same problems?  Anyone know how to overcome this?
I've never seen this kind of thing discussed.

Please check out my website: http://extraordinarycopywriter.com.  Maybe there's something non-meditative I can help you with?

Have a great Labor Day weekend.
