Thread: earthquake regularity

I veiw spaceweather.com, & Earthquakes, on that site i was watching the regularity of a 6.1 or higher on the planet. for Months at least 4+ we have had a 6.1 or better on the Earth average every 3-5.5 days. this kept happening until July 6th of which that was the last one. we did have 1 6.0 but not bigger since but it is kinda weird to go nearly 15 days now. Could this be a warning of a Large one building somewhere. does the Earthquakes of Earth usually slow down like this?

No, the distribution of earhhquakes is pretty much random. After a large quake (Mw > 7,5) there are many aftershocks that exceed Mag 6.

And part of the definition of "random" is that there will be periods with clusters of earthquakes of a particular magnitude and periods with an absence of them.

Some faults do steadily ratchet up pressure and periodically slip, like clockwork.

Megathrusts are associated with such faults, and follow the same ratchet/slip rule but at much greater interval and less regularity.

The good news is that for British Columbia's Cascadia Subduction small slip occurs at very regular 14-month intervals, and this provides danger windows for when the megathrust will come. Earthquake preparedness is best done in the week preceding these windows. Major hosted events like Olympics may be scheduled around them.

I liked Strange's choice to put quotation marks around random. The occurence of any earthquake, regardless of its magnitude, is very certainly not random. It is dependent on a variety of complex factors, such as regional tectonics, rock pore pressure, lithology types, stress regime, three dimensional structure, etc. However, the relative timing of earthquakes in toto is random.

Holy word that starts with an s!I've been doing that for the past 2 freaking years! You thought that up too!!??I knew I wasn't crazy! Something was up with that pattern! Did you read that article posted in the ny times about the new core layer discovered a few months ago? I think that has something to do with it. It's a new idea I bulit on. Some scientists believe that magnetic activity can be linked to seismic activity. This new core I read about proves it because it's made of purely concentrated iron. It's also moving twice as fast as the rest of the planet. That's how magnetic shift works! I knew that I couldn't be Wrong, because I predicted Japan!

There have been these little 2 or even 3 week intervals between this pattern, like earlier this month. That's usually followed by a major quake between 6.7 and 9. The core might be jostling and revirbarations might be sent pulsing through the mantle. This disrupts normal observable convection patterns. Or it could be geomagnetic disturbances could have a slight pull on magnetic metals within the crust enough to cause vibrations. Am I alone in this discovery?

Who was that addressed to? I can't see anything in any of the responses that matches the take you seem to have on things.

That's how magentic shift works.

There is no core layer moving twice as fast as the planet. Even if there were, that would not be 'how magnetic shift works'.

How unfortunate that the prediction followed rather than preceded the event. It rather makes a mockery of the definition of prediction.
