The biggest earthquakes make the Earth ring like a bell. But do earthquakes that rock the world increase the risk of new temblors?
Not by much, according to two reports presented today (April 19) at the Seismological Society of America's annual meeting in Salt Lake City. In fact, one recent quake near Sumatra, Indonesia, seemed to actually quiet global earthquakes.
The April 11, 2012, Indian Ocean earthquake was the largest strike-slip shake-up ever recorded. A strike-slip fault moves horizontally, as California's San Andreas Fault does. The magnitude-8.6 quake triggered earthquakes worldwidefor up to six days, said Fred Pollitz, a geophysicist at the U.S. Geological Survey's (USGS) Menlo Park, Calif., office.
But once the triggered quakes stopped, Pollitz was surprised to find a sharp drop in moderate

So like the finanaical markets, if we let market corrections heppen they relieve pressure on the system....
So imagine if we could “prevent earthquakes” by sealing the fault lines, and we would only have tiny tremors, that would be well and good, but guess what after a whiel the pressure would become so great that we would woozy of a earthquake we would lose control fo what we thought we had control of......
Interesting how the natural world can teach us about things that behave like forces of nature, like the markets and such....
I hate the word temblor. There is absolutely no reason to use it.
So a little logic and a guess here, if big earthquakes don't cause more earthquakes so much, wouldn't little bitty disturbances like fracking cause even less.
It looks like the environmental Communist DemoRat "progressives" are pushing another fraudulent crisis like all the others.
Exactly.

Me too:)
Alright, I’m not the smartest guy in the room but duh! I had this figured out a long time ago!
“Easy there, big fella.”
This makes sense, that in the short term it would help trigger other quakes, but in the intermediate term would cause some calming.
An important consideration is the “wave train” created by an earthquake. This is easiest observed in a tsunami created by the earthquake, whose series of waves can be measured in minutes or even hours.
But this is a wave train being propagated in water. A wave train propagated in rock will have a different character.
