Tonga volcanic eruption

On January 14, 2022 a large volcanic eruption resulted in an atmospheric pressure disturbance which was measurable on weather station barometers around the world. The energy from the eruption was estimated to be equivalent to 10 megatons of TNT (many times greater than typical nuclear bombs).
KL3RR-2 barometric pressure increased from 1003.5 mbar to 1005.2 mbar before dropping to a low of 1002.6 mbar. (Sensor measurement interval 15 minutes)
