Earthquake swarm in southern California

[vavavroom]

Mildly OT (but so is James Bond in this thread),

How so? A View to a Kill was set in the Bay Area and the villain's plan was to set off an earthquake that would destroy Silicon Valley. Fictional, yes. Dumb, yes? However, also more on-topic than either the East Coast or the Caribbean!

what’s the risk in UT?

We rarely feel a quake on the east coast, and in the Caribbean we get quite a few but don’t worry about them at all in concrete houses built to withstand cat 5 hurricanes…

Even more OT. I felt several minor quakes during my Japan trip a few months ago.

East coast is a quiet place seismically but we do get small/medium quakes from time to time. I'll point to the recent ~5 in NJ a few mos. ago this year and the larger one in VA about 10 years ago near Mineral. Makes sense...east coast is geologically v. old and no active tectonic margin but those old rocks have fractures and faults that will move from time to time. Let's not forget:

Someone, please wake me up when a >7.0 has hit.

Beat me to it. I will be out standing in my field.

I think @Jdeere562 is standing in his field right now.

Meh, I have about a week until the big one hits and then ample warning before the 1-foot tsunami devastates our local beaches about 10 hours later. I probably won't be here anyway.

Is California still shaking today,,,,,,,,,,,,,,,,,havent felt a thing in Chattanooga tn,,,all is ok here at the moment......................

1,000,000 fracked wells between 1940-2014, with >1/3 being post 2000.
Was there a cluster of fracked wells above Los Angeles (post 14)?

1-I want frack map
2-I need fault lines to enhance this thread. Are frackers merely following fault lines?
3-Searches reveal that the source of the hydraulic pressure required is never described. It's repeatedly referred to as "blasted".

are you kidding?

Concrete construction does not fare well in an earthquake, they disintegrate. The stress on a building are quite different between a hurricane and an earthquake.

Sure. But for the pretty frequent mild earthquakes they get, the concrete and rebar houses seem no worse for wear.

 

[Forest Grump]

Sure but it’s the not so mild ones which cause them to collapse. You have to mount this type of construction on springs.
