Unexplained Signal Detected Before Tonga's Massive Eruption
Researchers have identified a seismic precursor that occurred 15 minutes before the massive Hunga Tonga-Hunga Ha’apai eruption in January 2022, which was equivalent to hundreds of atomic bombs. This precursor, detected by distant monitoring stations, was caused by a collapse of the ocean floor, leading to a deadly tsunami and a massive plume of gas and ash. The findings highlight the potential for early warning systems to mitigate the impact of such eruptions.
