M7.8 Nepal earthquake - valley thrust supershear



Somewhere I have done a huge thing on blind thrust supershear earthquakes.  I even did a wikipedia on it.  The whole area is under compression because of mountain building.  Then they have these lovely valleys where everybody likes to settle.  But what are they really?  They are the scars of old thrust faults.  Each one goes every few hundred years, but there are a lot of them.  The PGV is record-breaking, if somebody could record it, probably 2 m/s or more.

Vancouver M6.1 walks down the track


This is right down at the bottom of the previous M7ish strike-slip earthquake,  This one is oblique thrust.


The big question is which track?  I am adamant about the buried strike-slip fault that defines the island, and goes way down into Seattle.  This is the real threat to Vancouver, but it is buried under a ton of sediment.  Pooh-pooh on the subduction zone, that is the worst-defined zone on the planet.  Other cities will tumble before this one does anything.

Being adjacent to the old quake, it could be a left-over or the start of the next section.  I make no predictions since my previous extrapolation was assuming the earthquakes were walking North to Alaska.

Just like Oklahoma, we could use some deep imaging here.

Maximum magnitude of 7!  Just like I said.  Oklahoma is the New New Madrid.  In fact, I think NM should be downgraded.  :)

Get your insurance before the Clueless Swiss read this.

Oklahoma comes clean about earthquakes

Reference

That's nice.  Now I don't have anything to do.  I can't make fun of the OGS or the usgus.  They have taken the more extreme position that it is all the water they inject, not just surface water.

It's too late for the oil industry to come up with this thought:

“It worked out smashingly right up to the point where it didn’t,” Mr. Hatfield said. “Something changed and we need to figure out why that is.”

They lied and cheated, and when the big earthquakes come rolling in, everything has to stop.  Think of the effect on oil prices!  Had they been honest sooner, they could have investigated the patented Fish Treatment. They could have injection and no earthquakes, but really, they should seal their boreholes.

So for now, all the government people are going for the Stupidity Defence, where they throw up their hands and say there is nothing they can do.  The earthquakes will go on.

Download is Dead, Bring Forth the Stream

The cooperative network of bittorrent has been thoroughly smashed by the slimy lawyers of the home box office.  They have sent depressing letters everywhere, and thus depressed the new economy by 2 points, throwing thousands out work.  Their infamy is now a close second to the Sony rootkit, and we know what happened to that company.

So, go sic 'em, my Mad Russians.  Nobody will morn.  Ask not for whom the bell tolls, Mr. boxoffice.

Now, instead of mutual cooperation, we will go to single-channel streaming sites, where they serve us every sort of porn ads.  All of it not covered by 'harperism put everybody in jail'.  When they do make a new law, we know what will happen to it.

So remove 'download' from your lexicon, everything is 'stream'.  I promise harp-nose that I will never 'download' again, I'm a stream-boy now!
