Cross-Domain Temporal Clustering Atlas: Inter-Event Time Analysis Across Environmental Metrics
Applying the coefficient of variation (CV) inter-event time method proven on earthquakes (CV=1.545) to CMEs, radiation spikes, geomagnetic storms, AQI exceedances, and flood events. Building a clustering atlas across domains.
The 1.545 above is the parent study’s result, Temporal Clustering of Global M4+ Earthquakes, measured on 118,009 M4.0+ earthquakes from 2021 to 2026. This atlas counted its own earthquake streams, so the M4+ figure in its key finding comes from a different set of events.
Key findingCV above 1
12 of 12 event streams bunch in time: the gaps between events vary more than random timing would give.
Time between events, the first 6 of 12 streams| Event stream | CV (random = 1) |
|---|
| Earthquakes M4+82,189 events, mildly clustered | 1.17 |
|---|
| Earthquakes M5+9,836 events, mildly clustered | 1.30 |
|---|
| Earthquakes M6+836 events, clustered | 1.32 |
|---|
| Kp Storms (≥4)12,804 events, clustered | 60.58 |
|---|
| Kp Major (≥5)5,914 events, clustered | 55.81 |
|---|
| CME Events9,043 events, clustered | 21.49 |
|---|
CV is the coefficient of variation of the time between events: its spread over its mean. Random timing gives 1; above 1, events come in bunches with long quiet gaps between.

When One Report Says Golf-Ball Hail, How Often Does the Next One Disagree?
Same-storm pairs of US hail reports, 1996-2025: of the neighbouring reports within a mile of a golf-ball report, 43.1% came in below golf-ball size (2010-2025), rising to 61.9% at 15 to 30 miles, against 78.5% for a report with no link.
