Apart from a very short introduction, the rest of the film is not for faint-hearted or those with claustrophobia. If you have issues with small spaces and feel irritated, even when shown on screen, this may be too much for you. Especially when you consider the running time of this. The earthquake and the people who are immediately affected by it (at one specific location) are very well portrayed and it is suspenseful if really draining to watch.
Any political context may be there, if you know of the political situation of the land as another reviewer suggested. As it is, I can't confirm or elaborate on that. For anyone not with any insight, this is just a very hard movie to watch. If you are up for that, then go ahead, just be aware this isn't easy or pleasant
