A team from Japan's Earthquake Research Institute detected a seismic wave just before the Hunga Tonga-Hunga Ha'apai eruption, providing insights that could enhance future volcanic eruption predictions.
Lead author Takuro Horiuchi stated, 'Many eruptions are preceded by seismic activity,' but such signals are typically subtle and only detectable nearby.
The massive eruption generated sound waves that traveled over 6,200 miles, highlighting its unprecedented power comparable to the historic Krakatoa explosion.
The study emphasizes the potential for real-time seismic analysis to aid emergency responders before future volcanic eruptions, marking a significant step in volcanology.
