What the record says

NCEI’s account, from the sources it cites.

Despite noisy data, we detect tiny but clear tsunami signals by utilizing the similarity of tsunami waveforms at nearby gauges. The analysis of the tsunami signals shows that submarine caldera uplift events occurred during both earthquakes, similar to past events […] occurred due to trapdoor uplifts in Kita‐Ioto Caldera (reference #14174)
