Book One
Entries open with an X5.1 flare and a run of elevated Schumann readings. Seismic activity for the same window is written into the same ledger, on the same dates, without interpretation.

Schumann power at five times baseline
Schumann resonance power read 50 — roughly five times the station baseline. A volcanic eruption at Hayli Gubbi was recorded the same day. An X1.7 flare followed on November 25. Telluric readings sat at 2.3× baseline.

M7.6 Izu Islands, Japan
M7.6 at 495 km depth, southeast of Honshu. Tsunami advisory issued; felt across the Tokyo metropolitan region. An X1.1 flare was recorded at 05:01 UTC and the seismic event at 14:15 UTC.
Third-party reading: the HeartMath Global Coherence Initiative logged power level 250 — its highest in that two-month span — across Lithuania (250), Saudi Arabia (125) and California (180).

Book Two
The January entries centre on a G4 severe geomagnetic storm at Kp 8. Storm parameters and the seismic record for the same days are both written down; nothing is inferred from the ordering.

M5.3 Bluff, New Zealand · M5.3 Tonga
Bluff at 19 km depth, Tonga at 10 km depth. Geomagnetic indices were rising as the G4 storm system approached.

How this log is kept
Entries are dated records of what public instruments reported. Seismic data comes from the USGS Earthquake Hazards Program. Solar and geomagnetic data comes from the NOAA Space Weather Prediction Center, GFZ Potsdam and Kyoto WDC. Schumann resonance readings come from the HeartMath Global Coherence Initiative, the Tomsk SOS-70 observatory and the Cumiana VLF station.
Events appearing near each other in this log appear near each other in time — nothing more. No relationship between electromagnetic activity and seismic activity is asserted, tested or implied here, and this log is not used to forecast earthquakes. It exists so the raw record is public and anyone can check it against the same sources.
