Unofficial. These are research results from Shake3D, a volunteer-run monitor. It is not affiliated with or endorsed by GeoNet, NEMA or Civil Defence; GeoNet’s catalogue is the official record. Results refresh in the background and can be several minutes old.
🔬 Transparent Multi-Station & Detector Verification
Recorded source solutions and fusion decisions compared with the current GeoNet felt-event feed (MMI ≥3). Network readings are shown as unassociated motion, not proof that an earthquake was detected. Historical demonstrations are excluded; only recorded results appear here.
Measurement rule: A station reading is not an alert. Fusion confirmation, shadow forecasts, and delivery outcomes are reported separately. Bulletin advantage compares recorded confirmation with this monitor’s first GeoNet receipt; it is not pre-shaking warning time.
