The most interesting evidence-backed connections uncovered across WIVVI’s research.
Collective animal activity preceding earthquake occurrence
The study reported elevated collective activity among monitored farm animals before some nearby earthquakes while the animals were housed in a stable. The pattern was not detected consistently while…
Evidence Strength: 25/100
Interpretation Confidence: 85%
Electromagnetic anomalies preceding earthquake occurrence
Published reports describe electric, magnetic, geomagnetic, radio-propagation, and ionospheric anomalies during periods preceding some earthquakes. Proposed explanations include stress-related…

Bird behavior preceding earthquake occurrence
A camera-trap study in the Peruvian Andes reported a decline in recorded terrestrial mammal and bird activity during the weeks preceding one magnitude 7.0 earthquake, with no animal activity recorded…
Evidence Strength: 20/100
Interpretation Confidence: 85%
Groundwater anomalies preceding earthquake occurrence
Some studies report changes in groundwater level, temperature, pressure, flow, or chemistry before nearby earthquakes. However, findings are inconsistent and often site-specific, while rainfall,…

Dairy-cow milk-yield changes preceding earthquake occurrence
An observational time-series study reported that dairy-cow milk yields varied systematically before a selected set of nearby earthquakes, including a negative association approximately three weeks…

Honey-bee colony acoustic changes preceding earthquake occurrence
A retrospective study reported changes in statistical properties of acoustic noise recorded within a honey-bee hive during selected periods preceding earthquakes. The authors compared these changes…
