I can't remember who did this image... maybe Ryuneo? But I could've sworn it was somebody on this forum a while back.
It's the image of Tower Bridge (London) being over taken by a huge wave.
Figured the artist would like to know what's going on here:

Doc, I don’t recall ever seeing that Photoshop image before but a
quick search did reveal the artist and the winner of a wallpaper contest.
Finally figured out what I was remembering... Morpyre's destruction series!

Looks like that one I was referring to is different though... I just KNEW I had seen something like it somewhere!
