Story: Historic earthquakes

Aftershocks, 22 February 2011 to 11 February 2012

Choose magnitude:

  • 0–2.5

  • 2.5–3.0

  • 3.0–3.5

  • 3.5–4.0

  • 4.0–5.0

  • 5.0–6.0

  • All since 4 September 2010

Following the magnitude 6.3 Lyttelton earthquake on 22 February 2011 there were many aftershocks. Seismologists believe that the 22 February quake was itself an aftershock of the magnitude 7.1 earthquake centred on Darfield on 4 September 2010. At magnitude 6.3, the Lyttelton quake was so large that it generated its own series of aftershocks.

I think there is a way to "rotate" information so as to reveal previously hidden aspects; possibly allowing dramatic advances in earthquake-forecasting through pre-quake signature build-up patterns (of stress (re) distribution) (leading to the type of cohering structures that would appear to be a necessary (from physics perspective) state for an actual earthquake to occur) (I haven't read the "disclaimer") (Higher dimensional sorting of information!.......)(I am writing a document on this and related subjects)
