^ According to this. Yeah it is, and there's multiple interviews that say that it is. Plus the movie Kong Skull Island using the date when Monarch was established from the graphic novel and not the 2014 Godzilla film is further evidence. There's other things to consider as well. The post credit scene in Kong Skull Island reveals that Godzilla has awaken throughout earths history, just like what the graphic novel says, and more recently the monarch timeline includes General Macarthur. A character from the graphic novel.
Some of the inconsistencies from Awakening & 2014 film can be solved by simply remembering that Monarch is a secret organization that won't reveal the entire truth about Giant Monsters owning this earth. What they told to Ford was a cover story that simply only involved the Monsters in question, and keep everything else under wraps. Especially when you take a look at there timeline. They have been keeping track of MUTO'S throughout the years, and even contain some.
PS. Dr Serizawa age means nothing. Especially when the actual actor is 57. He can totally play someone who is 69 in the 2014 film. That's just a couple of years. Hell the pocket watch that he talks about in the film is present in the graphic novel. On another note the kilotons vs megatons was obvious a mistake that slipped through the crack. It happens all the time in movies.
