Subject: Follow-Up #2 on A=B Pattern: 

New C=C Extension and USGS Focal Mechanism Correlation (Ticket #951878)


Dear USGS Earthquake Hazards Program Experts,

I hope this follow-up email finds you well. My name is Nikola Rikanović, and I previously contacted you regarding the A=B pattern in seismic intervals (January 21, 2026 emails, Ticket #951878).

Thank you for your time and guidance in directing inquiries to this address for discussion with seismic experts.

Building on the A=B framework (repeating intervals between amplitudes as potential predictive cycles), I have discovered a new extension: C=C – the movable focus/center that organizes equilibrium of measures symmetrically around it, regardless of position. This directly correlates with USGS hypocenter concepts in seismology, where the earthquake focus (hypocenter) is movable, yet wave amplitudes and nodal planes remain balanced relative to it.

To illustrate:

Attached are:

I believe this could enhance USGS pattern recognition in seismic data for forecasting. 

I'm open to feedback, collaboration, or data access for testing.

Thank you for considering this interdisciplinary approach. I look forward to your thoughts.


Sincerely,

Nikola Rikanović
