The Earth Resonance Initiative
An interdisciplinary research project exploring measurable relationships among Earth-system signals, environmental phenomena, and biological activity, with particular interest in potential earthquake precursors and early-warning applications.
The Earth Resonance Initiative (ERI) investigates whether measurable relationships exist among geophysical, electromagnetic, atmospheric, hydrological and biological signals associated with Earth-system activity. Its initial focus is earthquake-related phenomena, including whether combinations of signals such as seismic activity, ULF/ELF electromagnetic variation, groundwater changes and animal behaviour contain reproducible information that could contribute to earthquake early warning. ERI uses an interdisciplinary, evidence-led approach in which proposed relationships are tested against published research, alternative explanations, negative findings and appropriate controls. More exploratory hypotheses—including possible relationships involving resonance, mineralogy and electromagnetic coupling—are treated as hypotheses to be tested rather than established mechanisms.

Findings & Evidence
Taxonomic shifts in animal activity before the Contamana earthquake — finding 3
During the pre-earthquake period, the taxonomic composition of animals recorded by camera traps changed. Rodents, normally the most abundant animals in the study area, became scarce as the earthquake approached, while some other taxa, including armadillos, continued to be recorded during the final days before the event.
Animal activity prior to earthquake — finding 1
Animal detections recorded by motion-triggered cameras declined over approximately three weeks before the 2011 magnitude 7.0 Contamana earthquake, with the decline becoming more pronounced during the final eight days. No animal movements were recorded on days 10, 6, 5, 3, 2, or on the day of the earthquake.
Ionospheric VLF perturbations before the Contamana earthquake — finding 2
Night-time very-low-frequency (VLF) phase perturbations were observed along a propagation path passing over the epicentral region before the 2011 magnitude 7.0 Contamana earthquake. The perturbations began about two weeks before the event, with a pronounced fluctuation around eight days beforehand.
