A catastrophic eruption destroyed the Tongan island of Hunga Tonga-Hunga Haʻapai at 04:14 UTC on 15 January 2022. This event triggered a series of enormous ripples that spread out across the Earth. Atmospheric pressure observations recorded outside and inside the British Cave Science Centre at Poole’s Cavern, Derbyshire, present evidence for two phases of anomalous behaviour between c. 18:30 and 20:30 UTC on 15 January and c. 01:30 and 02:30 UTC on 16 January. These are thought to have been initiated by a Lamb wave circling the Earth. Visual inspection also identified a series of smaller perturbations repeating approximately every six hours until 17 January and renewed instability culminating on 19 January. In contrast, automated anomaly detection only pinpointed the larger anomalies on 17 and 19 January. Further research is needed in order confirm the existence of these later anomalies and to better understand their relationship with the volcanism in the southern Pacific.
