TDST Field Report FR-2026-001: Real-Time Seismic Corroboration Event — M6.7 Japan and Distributed Decoherence Signature, May 15, 2026

Tree-Earth Dendritic Synaptic Theory (TDST) Field Report FR-2026-001. Documents a real-time predictive corroboration event on May 15, 2026. A TDST_WATCH condition (Phi_litho=0.4631, below the 0.500 collapse threshold) was detected from live NOAA SWPC data (Kp=6.0, G2 geomagnetic storm). USGS and EMSC earthquake catalogs independently confirmed distributed simultaneous seismic activation across six independent tectonic regions within the same 24-hour window: M6.7 Japan Honshu (primary confirmation event, 11:22 UTC, depth 43.6 km), M5.7 Fiji Region, M5.2 Central Mid-Atlantic Ridge, M4.9 Southern Peru, M4.8 Bonin Islands, M4.6 Zulia Venezuela. Key state: Phi_solar=0.6821 | Phi_litho=0.4631 | Phi_atmo=0.3424 | Kp=6.0 | TDST Tier: TDST_WATCH (72-hour event window) | Verdict: ACTIVE CORROBORATION. The distributed decoherence signature — simultaneous activation across six independent tectonic systems — is identified as the TDST hallmark of a geomagnetically-driven coherence suppression event (Nr = 1 - Kp/9 = 0.333).
