Part 8/14:
Scientists have investigated natural precursors such as electromagnetic signals, gravity changes, and radon gas emissions. Radon, a radioactive gas trapped beneath the Earth’s surface, can indicate micro-fractures forming inside rocks prior to an earthquake. However, the variability of influencing factors like rainfall and soil composition complicates these signals' interpretation. While there are instances where anomalies were detected days before a quake, inconsistencies prevent reliable long-term forecasts.
