Earthquakes are known to be highly correlated (that's why you have pre- and after-shocks and why low seismicity means both lower frequency and lower intensity.

Earthquakes are one of the most interesting phenomena whose every aspect displays fractal statistics and whose dynamics is possibly chaotic...

While multifractality of the earthquake process is confirmed in every way...

Absolutely (none / 0)

It has been understood that a fracture network is a self-organising system capable to operate at all scales (micro, meso, macro).

Re: Absolutely (none / 1)

But, moreover, probabilistic intuition trained on "regular" memoryless processes such as the Poisson process is misleading, which is where the "anomalous number of recent earthquakes" argument is coming from.

Re: Absolutely (none / 0)

Oh, and a fracture is understood as a network and not a single fault?

No (4.00 / 2)

Technically, a fracture is a fracture; a fault is a fracture which has undergone (tectonic) movement. Both can occur at all scales. However, a fracture network at the micro scale has the potential to develop into a fault at the meso/macro scale. Faults organize them in networks - fault zones - fractally identical to a network of micro fractures or micro faults.

One fracture is just a fracture; a single fault is derived from a network of micro/meso fractures.
