How Would a Continental Landmass Sink?

+0

Atlantis is real. It's just that there's more than one of them, and none of them are actually called "Atlantis". Instead, they consist from the Kerguelen Plateau in the Indian Ocean to Zealandia, a continent who sank 130 million years ago, leaving their highest points to be the North and South islands of New Zealand.

Here is a map of an alternate Earth that I've been working on:

enter image description here

Our focus here is on two different areas--Western Asia and Japan. At first glance, it'd look as though those two landmasses never existed. The truth is, in this alternate Earth, they sank. Western Asia had sunk very early in the Eocene, Japan no longer than 15 million years ago. What force of nature could possibly sink the specified landmasses?
