What was discovered
A method proposed to predict earthquakes from low-frequency electrical signals detected in the ground before shocks. Its predictive value has been strongly contested.
The 1996 debate in Geophysical Research Letters set defenders against critics (among others, Geller); the community does not accept it as a reliable prediction method. It is kept as a milestone of historiographic interest.
What it led to
- scientific debate on earthquake prediction
- research on electromagnetic precursors of earthquakes
