If anyone notice in the second picture there is a whole region that got drowned in Morrowind, does that mean there going to be an underwater city ? that would be awesome.

Yeah, I noticed it. Maybe it has something to do with the plot of the novel? 

And yes, an underwater city would be awesome as hell.

According to OP:

"This pic shows the geological evolution from the currently still played Elder Scrolls IV: Oblivion, thru how it looked like during the Vvardenfell Red Mountain mega-super-eruption as depicted in the Elder Scrolls Novel Inferno City"

Not sure it'd be an underwater city so much as the complete destruction of the Vvardenfell island (and from that pic, all of Morrowind as it looks like Black Marsh has taken over the remaining mainland of Morrowind).
