You might, therefore, be tempted to wish it into the daylight, when tourists would have been afoot, as then it might have garnered more notice-since it came in pulses of ascending violence, there would have been time to run, and the headlines would have been nothing more than ‘Tour operators reassess risk after near miss’. You might wonder if this eruption triggered any changes, but it happened at night, with no witnesses, so it simply passed on by. “These eruptions clearly pose a significant hazard to the tourists that visit the island,” the authors wrote. The pyroclastic surge, though just five millimetres thick at its extremities, had nonetheless covered 95 per cent of the track. It then took nearly three years before the resulting scientific paper was published, on April 1, 2019, and laid out the facts: more than a quarter of the walking track had been bombarded by rock fragments. GNS Science geologists reconstructed the pulses of the eruption from acoustic and seismic data, and three weeks later-when they could safely land on the island again-they began figuring out the reach of those pulses. This eruption took place on Whakaari/White Island on April 27, 2016. A scalding current of steam and debris, coloured green by the hydrothermally altered rock it contained, rolled right over the walking track at 11 metres per second, and down to the south-eastern bays. At 10.03pm, it began pelting the walking track with projectiles, but withheld its final energy until 10.11pm when, with a whoomph, it sent the plume sky-high.
The eruption started at 9.35pm, with big heaves inside the crater.
