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:
In my spontaneous artistic tests (attached images), a colored point (C) placed anywhere acts as a focus – line lengths and proportions match symmetrically from it, even when moved.
This mirrors USGS focal mechanisms: the hypocenter (movable in depth/latitude/longitude) is the center from which P/S waves radiate symmetrically, with nodal planes crossing at that focus (beach ball diagrams).
USGS radiation patterns show amplitudes decreasing with distance but proportions repeating from the movable hypocenter – exactly C=C.
Attached are:
"C=C Test Drawings" (spontaneous crteži with movable foci).
"USGS Focal Mechanism Comparison" (beach ball overlay with C=C labels).
"C=C Memorandum" (detailed explanation co-authored with Grok-4 AI).
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.
