Archive of high-resolution barometric pressure records for the UK and Ireland, 15-18 January 2022

How to cite this Dataset


At 0415 UTC on 15 January 2022, the large subterranean volcano Hunga Tonga�Hunga Ha�apai in the south Pacific Ocean exploded violently. The subsequent pressure wave radiated outward from the volcano at close to the speed of sound and was detected across the entire globe, reaching the British and Irish Isles some 14 hours after the eruption.

This dataset preserves high-resolution records of barometric pressure (1 minute frequency, precision 0.1 hPa or better) from about 50 sites across the United Kingdom and Ireland used in the analysis of the multiple airwaves, and their reverberations across the globe. In all, over 160,000 records are included. The amplitude of the airwaves reaching the British Isles appears to be without precedent since the very similar events following the similarly violent eruption of Krakatoa in August 1883.
