Scientists have now “discovered” something that I have been telling (and showing) my viewers / readers for the past several years.
Seismic pressure caused by large earthquake activity is causing other earthquakes up to 1,000km away.
These new findings, made by Italian scientists, indicate seismic pressure is causing “particles” in the Earth’s crust to vibrate (resonate) on a certain frequency which induces particulate matter to slip along far adjacent fault zones.
In otherwords, pressure from a large earthquake can cause vibration on layers of the crust several hundred to over a 1,000km away from the original earthquake epicenter.
Simply put, a large earthquake can cause another earthquake far away.
We see this happen across the North American Craton every few weeks, earthquake progression where seismic pressure in one area causes an earthquake in another region.
Up until now, professionals have literally been frequenting my pages (and videos) DENYING that earthquakes are related across large distances like this.
Now these denying professionals are corrected by other professional researchers. As if showing everyone via my videos for the past few years isn’t proof enough.
I just talked about this topic, the fact that earthquakes are related over a distance, in my most recent Earthquake Forecast video:

How earthquakes can trigger copycat quakes 1000 kilometres away
21 September 2015
“Seismic waves unleashed during Wednesday’s magnitude 8.3 earthquake in Chile could have triggered aftershocks as far as 1000 kilometres away.
That’s because they can shake up grains of rock wedged inside distant faults. According to computer models, even weak waves at the right frequency could be enough to start a new quake by vibrating that grist into a more slippery, liquid-like layer.
Earthquakes often happen when two tectonic plates that have been pressed together suddenly slip. But we’ve seen that major earthquakes like 1992’s Landers earthquake in California can also send out waves that spark copycat quakes 1000 kilometres away, even though the waves get weaker as they travel.
The mysterious remote triggering of quakes may have also played a role in events in Chile in 2014, and Japan in 2011.
“We were wondering: how could it happen that a very tiny wave with a very small amplitude could trigger earthquakes a thousand kilometres away?” says Lucilla de Arcangelis of the Second University of Naples in Italy.
One idea is that sound waves can lather up the grains between the two plates in a way that decreases friction, to make a slip easier. Now a team including de Arcangelis has built a computer model that shows the process as it happens.
They found that seismic waves could trigger an earthquake in the simulated fault only if they came in a narrow range of frequencies. If the fault was just about to slip, it would hasten the process by starting vibrations in that range. Only the frequency really mattered – weak waves, or even waves that would actually push in the direction against a slip, could still induce an earthquake.
“Each fault will have its own acoustic resonance frequency,” de Arcangelis says. “If a signal arrives at this frequency, the fault that without perturbation would be quiet will trigger an earthquake.”
Combined with a 2005 lab experiment that also showed a resonant frequency could jiggle glass beads in a fake fault into slipping, this simulation could suggest that actual faults have specific frequencies they’re susceptible to

Vibration of Small Particles Could Trigger Aftershocks of Earthquakes
“Earthquakes can create copycat events up to 1,000 kiometers away — and it could be the result of the vibration of small particles, according to new computer simulations of seismic activity in the Earth.
New Scientist reports that a team of researchers from the Second University of Naples in Italy has developed a computer model that analyzes the way grains between tectonic plates influence friction forces felt at their boundaries. The team has shown that at certain frequencies, small particles between the plates can becomes ‘lathered’, moving around and decreasing friction, making slip — and an earthquake — more likely, even up to 1,000 kilometers away.
Interestingly, they found that the magnitude of the seismic waves emanating from one earthquake don’t have much effect on the likelihood of inducing another earthquake — it’s just the frequency. “Each fault will have its own acoustic resonance frequency,” Lucilla de Arcangelis, one of the researchers, tells New Scientist. “If a signal arrives at this frequency, the fault that without perturbation would be quiet will trigger an earthquake.” The research is published in Physical Review Letters.
In fact, the researchers claim that the effect could been what triggered aftershocks which occurred after last week’s earthquake in Chile.”
For the record:
Professor Vidale came on the attack to my pages rather UN-professionally.
This well credentialed “professional” made several personal (ad hominem) attacks on my character, then followed up by making several scientific denials.
Specifically, Professor Vidale denied that one earthquake can cause another earthquake elsewhere far away.
Now John Vidale is proved wrong thanks to the work of real scientists who are willing to question the basic dogmas of Geology + Seismology.
