Satellite images caught the dramatic growth of the volcanic plume, and the subsequent pressure wave which radiated outward from the volcano at close to the speed of sound. The initial pressure wave, and its subsequent reverberations, was detected across the entire globe, reaching the British and Irish Isles some 14 hours after the eruption. Several subsequent reverberations of this pressure wave could be detected in the British and Irish Isles up to 127 hours after the eruption, in what appears to have been the largest amplitude airwave event caused by a distant natural phenomenon since the Krakatoa eruption of August 1883.
