New Zealand, as part of a small continent, Zealandia?

AI Thread Summary
Tasman's 1642 expedition to New Zealand ended abruptly after violent encounters with the Māori, leading him to name the location Moordenaers Bay and abandon his mission without setting foot on land. At the time, Europeans were unaware of the existence of Zealandia, a submerged continent later identified by geologists in 2017. Zealandia, also known as Te Riu-a-Māui, spans 1.89 million square miles, making it the smallest, thinnest, and youngest continent, with 94% of its area underwater. This discovery challenges the long-held belief that there are only seven continents. Additionally, discussions have emerged linking underwater geological features to historical accounts, such as Plato's description of Atlantis, suggesting that ancient myths may have roots in real geological events.

on 14 August, Tasman set sail from his company's base in Jakarta, Indonesia, with two small ships and headed west, then south, then east, eventually ending up at the South Island of New Zealand. His first encounter with the local Māori people (who are thought to have settled there several centuries earlier) did not go well: on day two, several paddled out on a canoe, and rammed a small boat that was passing messages between the Dutch ships. Four Europeans died. Later, the Europeans fired a cannon at 11 more canoes – it’s not known what happened to their targets.

And that was the end of his mission – Tasman named the fateful location Moordenaers (Murderers) Bay, with little sense of irony, and sailed home several weeks later without even having set foot on this new land. While he believed that he had indeed discovered the great southern continent, evidently, it was hardly the commercial utopia he had envisaged. He did not return.

(By this time, Australia was already known about, but the Europeans thought it was not the legendary continent they were looking for. Later, it was named after Terra Australis when they changed their minds).

Little did Tasman know, he was right all along. There was a missing continent.

In 2017, a group of geologists hit the headlines when they announced their discovery of ZealandiaTe Riu-a-Māui in the Māori language. A vast continent of 1.89 million sq miles (4.9 million sq km) it is around six times the size of Madagascar.

Though the world's encyclopaedias, maps and search engines had been adamant that there are just seven continents for some time, the team confidently informed the world that this was wrong. There are eight after all – and the latest addition breaks all the records, as the smallest, thinnest, and youngest in the world. The catch is that 94% of it is underwater, with just a handful of islands, such as New Zealand, thrusting out from its oceanic depths. It had been hiding in plain sight all along.

Interesting idea.

Yes, it seems a lot of new discoveries now consider underwater features too. There was a recent article on comparing Plato’s description of Atlantis with Santorini once the site of a supervolcanic explosion and tsunami.

In his description there was something about a circular harbor with an island in the middle and other landmarks and dimensions that were borne out if you consider the 400ft sea rise that hid the Cyclades Plateau underwater.

On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.

Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...
