What will the Far East look like in a few tens of millions of years?

Since I am not a scientist, it will not be easy to predict. Considering the fact that there is a lot of seismic activity, as well as a rise in the level of the world ocean, it can be assumed that over time, part of the Far East will be flooded with water. For example, Vladivostok and part of the Primorsky Territory may completely go under water. Also, due to large warming, part of the territory can turn into a desert and become uninhabitable. Do not forget about the great volcanic activity, which can lead to the fact that there will be a large amount of ash in the air. In any case, forecasts for a person’s life are disappointing.
