A sequel to last year's disaster film, "San Andreas," is in the works at New Line and Dwayne "The Rock" Johnson is set to reprise his role as rescue pilot Raymond Gaines in the film, according to The Hollywood Reporter.

"Cool news you made #SanAndreas Warner Bros' biggest hit of 2015 and our sequel is now underway," announced Johnson via an Instagram post.

Neil Widener and Gavin James were chosen to write the screenplay of the sequel. Director Brad Payton and the original cast, including Carla Gugino, Alexandra Daddario and Paul Giamatti, are expected to return.

"San Andreas" followed the story of search-and-rescue pilot Gaines and his attempt to save his family from the wrath of a massive earthquake that hits California.

Johnson added that the sequel will be international and focus on the Ring of Fire - an area in the basin of the Pacific Ocean - where large numbers of earthquakes and volcanic eruptions take place.

"With the research we've already done its mind boggling how massive the #RingOfFire truly is. We're assembling an awesome team of filmmakers to raise the bar, raise the stakes and deliver something to you that'll be unforgettable," added Johnson.

"San Andreas" had an incredibly successful run at the box-office and was Warner Bros. highest grossing film last year, collecting more than $473 million globally, according to IGN.

Johnson's Seven Bucks Productions will be producing the project along with Peyton.
