The first person known to have sighted the island was the Spanish explorer Juan Sebastián de Elcano, on 18 March 1522, during his circumnavigation of the world. Elcano did not give the island a name. On 17 June 1633, Dutch mariner Anthonie van Diemen sighted the island, and named it after his ship, Nieuw Amsterdam.

Volcanic activity died down on 5 January[50] before restarting on 13 January after the volcano sent an ash cloud 17 km (55,000 ft) into the atmosphere.[51] The government subsequently issued a tsunami warning.[52][53] On 15 January, the volcano violently erupted again, about seven times more powerfully than the eruption on 20 December 2021. There were numerous reports of loud booms across Tonga and other countries, such as Fiji and as far away as New Zealand and Australia.
A much larger eruption started that day (14 January) at 17:15 local time (UTC04:14:45, 15 January)
Intense lightning activity was recorded during the eruption phase. The Vaisala National Lightning Detection Network detected the lightning in the form of radio waves. Several hundred to a thousand flashes of lightning were recorded by the system during the two weeks prior to the eruption. From 14 to 15 January 2022, tens of thousands of lightning flashes occurred.[36] Between 05:00 and 06:00 UTC on 15 January 2022, 200,000 flashes were recorded
