Last 30 days: every M6.0+ earthquake on Earth

Ground truth: the USGS ComCat catalog — so a miss is a real miss and shows here the day it happens. HIT = the event was preceded by a logged, hash-anchored forecast that later matched it.

Coverage: M6.0+ 13/13 · M5.5+ 52/54 · M5.0+ 177/192 (coverage of catalog events by matched forecasts — not a skill claim)

Does this beat chance? The measured answer.

On where to look — not yet. We currently hold 88.1% of the world's seismicity under alarm and catch 87.3% of the earthquakes (350/401, 90 d, M5.0+). Alarming that same fraction of ground at random would catch 88.1%. Area Skill Score 0.4807, where 0.5 is no skill — integrated over the full alarm-threshold trajectory, not a single operating point (the single-point approximation reads 0.4960, which is optimistic). This number cannot be improved by alarming more — widening the alarm drives it toward 0.5 by construction.

On how likely — yes, newly. After per-model recalibration, 4 of 5 models reach positive out-of-sample skill (n-weighted mean of per-model out-of-sample Brier Skill Score +0.0615, where 0 is no better than quoting the base rate), from an expanding-window walk-forward. Recalibration is monotone, so it moves this number and leaves the Area Skill Score untouched — they are different products.

Separately, conditioned on a forecast having been issued: the when-issued full-magnitude rate is 70.6% (n=520, trailing 30 d, expired M4+) against 28.7% for naive USGS-catalog climatology, walk-forward backtest Aug 2026. That is a narrower question than the two above — it says nothing about how much ground we alarmed to get it, which is exactly what the Area Skill Score measures. Reproducible from public catalogs; every forecast hash-anchored before its event.

Where earthquakes cluster — the hazard map.

On where they happen — yes. Our smoothed-seismicity map places 95.6% of real future M5.0+ earthquakes within 50 km of where it flags — a median miss of just 6.6 km (Molchan spatial score 0.978, where 0.5 is no skill), tested out-of-sample on 5018 earthquakes the map was never trained on.

Read this correctly: this is WHERE earthquakes cluster — the field-standard seismic-hazard map — not WHEN one is coming. The 0.978 is spatial localization; it is not a percentage of earthquakes predicted, and picking the day remains at chance (see above). A full forecast is where × when × size — this is the where, done honestly and reproducibly from public catalogs.

Open Forecast Skill Exchange NOW OPEN

The track record above is ours. The Exchange is the open version: a public, hash-chained, pre-registered scoreboard anyone can enter. Every submitted forecast is SHA-256 hashed and its hash committed to a tamper-evident chain before its window opens; it is then scored against the public earthquake catalog (USGS ComCat) on a fixed monthly cadence. Outcomes are annotated, never rewritten — the same discipline our own ledger runs under.

What makes a score trustworthy here
  • Forecast hash anchored before the window — no hindsight edits.
  • Ground truth is ComCat, re-runnable by anyone with one public API.
  • Magnitude floor M4.5 global (M4.0 inside dense US coverage, which is complete to M3.5 across ~97% of the conterminous US — see the coverage polygon), so a miss is a real miss.
  • Skill is reported with its alarm volume (Area Skill Score), never as a bare hit rate. Coverage is labeled coverage, never skill.
How to take part
  • Open lane at launch: submissions and scores are public.
  • Opt-in only. We never score a named person's public predictions without their submission — you enter your own forecasts, or a baseline we implement from a published method.
  • Register (double opt-in) and submit via the API: /api/v1/exchange/.

Convergence Gate — multi-physics N≥3 agreement 97% specificity by construction (requires ≥3 channels at |z|≥2) ARMED · AWAITING

Fires only when ≥3 independent physics channels (seismic, electromagnetic, gravity, atmospheric, particle, oceanic, thermal, fluid) each cross a 2σ threshold in the same 15-min tensor snapshot. By construction, the expected false-positive rate at this gate is <3% for uncorrelated channels. This is the highest-precision, lowest-volume product in the ledger.
The gate is running on AX41 (13 * * * * cron); it has not yet produced its first ledger fire. That is expected behaviour at design-threshold: fires are supposed to be rare.

Cascadia + San Andreas Paired-Megafault Watch Goldfinger 2025 paleoseismic prior · 0.2%/yr LOADING…

Tests whether the Cascadia subduction zone AND the southern San Andreas (UCERF3) are both elevated above their typical 7-day rate in the same window. Goldfinger et al. 2025 (Geosphere 21(6):1132) identifies 3 paired Cascadia+SAF events in 1,500 years from sediment-core turbidite analysis -- the 1700 paired M~9 + M~7.5 is the most recent example. The paper deliberately stops at correlation; this card follows the same discipline.

Industrial Magnitude Cascade Phase 65o — T-7d → T-36h → T-24h per region

Per-region tiered-horizon cascade for industrial shutdown protocols (smelters, chip fabs, rail). Each of the ~54 monitored earthquake regions independently emits up to 3 linked predictions per run — T-7d early warning, T-36h convergence tightening, T-24h industrial alert. Confidence thresholds are 0.60 / 0.75 / 0.85. Every tier carries the M0.5 band (or M0.25 once a region graduates on residual sigma ≤ 0.30 with ≥ 30 matched obs), a 95% CI, and a SHA-256 hash-chain entry.

Tensor-Trained Solar Flare Classifier Phase 65h — real GOES X-ray outcomes

First solar-flare classifier trained on real outcome labels instead of rule-based synthetic data. Inputs: 9,687-dim Earth State Tensor + time-series delta. Target: M-class+ (or M-class+) solar flare in the next 24 hours. Labels come from NOAA SWPC GOES X-ray flux. Replaces the synthetic-trained classifier stuck at 17.1% real hit rate.

Per-Geyser Skill Breakdown (narrow products vs. bulk predictor)

Last 30 days, post-PR#28 cadence-artifact fix (Apr 20). Bulk Old Faithful is now logged as one prediction per predicted eruption (was every ~10 min; the old number was a cadence artifact, not skill). Specific geysers (Daisy, Beehive, Riverside) are scored per-eruption. Small N (n<10) and irregular-cadence research-tier geysers are badged so 100% on n=6 doesn't read the same as 100% on n=60.

Old Faithful Eruption Coverage (reformulated metric)
73.5%
1060 of 1443 distinct Old Faithful eruptions caught across 166.7 operating days (8.7 eruptions/day average per GeyserTimes).
This is the right question: "of all the eruptions we know happened, what fraction did we catch?" The bulk hit rate above answers a different question (per-prediction precision, naturally low because of cadence). Both metrics are honest; this one is the operationally meaningful one.
Tensor-Trained EQ Classifier (real outcome targets, leave-one-out cross-validated)
Global classifier (M6.0+ in 7d)
0.969
LOOCV AUC trained on 8760 earth state tensor snapshots (5657+ / 3103- balanced binary task). Brier 0.049.
First real outcome-trained EQ model (real USGS labels, not synthetic). Retraining weekly as snapshots accumulate at */15 cadence.
Holdout caveat: in a sealed out-of-sample test this model family's score fell to chance (held-out AUC 0.496, hypothesis HYP-9fb3d2fa, adjudicated 2026-07-20) — treat the cross-validated number as a ranking score, not live forecast skill. The live ledger record above is the operational metric.
Per-region classifiers (M4.5+ in 7d)
0.980
Mean LOOCV AUC across 113 trained regional models (16 regions skipped, awaiting more data).
Same holdout caveat applies (HYP-9fb3d2fa: held-out AUC 0.496 = chance). The when-issued ledger rate for this model — 80.1% over n=272 matched predictions — is the number to trust; LOOCV AUC is a ranking score only.
Top regions by AUC: caribbean_lesser_antilles 0.99 andaman_nicobar 0.97 juan_de_fuca_ridge 0.98 new_zealand 0.99 mid_atlantic_ridge 0.98

Trained on the unified Earth State Tensor (9,687 cross-physics features, hourly snapshots). Inputs include real-time gravity, solar wind, electromagnetic, oceanic, particle, fluid, atmospheric, and seismic measurements. Outputs are calibrated probabilities of M6.0+ events, cross-validated leave-one-out. Cross-validation is not a temporal holdout; see the holdout caveats above.

Verification Methodology

Every prediction is SHA-256 hashed at creation time and added to a tamper-proof hash chain. When a real-world event occurs (confirmed by USGS, NOAA, EMSC, NASA FIRMS, or NWS), the system automatically matches it against pre-existing predictions within 300km and 7 days.

Grading: A (80+ pts) to F (<20 pts) based on distance accuracy (0-50 pts) + prediction lead time (0-50 pts). Grade A requires <50km distance accuracy AND 72+ hours of advance warning.
