At least Earthquake -- a clear inspiration for this film, even if its release date of 1974 makes it seem as long ago as the Dead Sea Scrolls -- jumped between characters and showed a real L.A. populated by cowards and heroes, daredevils and madmen, Charlton Heston and Richard Roundtree.
It’s essentially a remake/ripoff of the 1974 disaster movie nadir “Earthquake,” only there’s only a handful of characters, not the usual three or four dozen.
Earthquakes haven't been exploited at the movies as much as one would think (most prominently in 1974's Earthquake, which brought us the Sensurround gimmick), but those with long-memories can cross-reference 1997's Dante's Peak and Volcano, which are more or less the same movie as (each other and) San Andreas, except with geysers of lava.
And as we all know, sound technology has come a long way since the 1974 Charlton Heston “Earthquake” movie introduced audiences to something called SenSurround.
Of course, San Andreas is really about destruction, and the orgy of cracking earth, collapsing dams, tumbling buildings, and rushing tsunamis is all expertly rendered, missing only the theater-shaking gimmick of Sensurround, which shook audiences watching Irwin Allen’s infamous Earthquake (1974).
Even 1974’s Earthquake at least had sensurround and seats that shook.
