This is real:

... a massive, spontaneous sinkhole ("hundimiento") that appeared today in Zone 2 of Guatemala City, after overwhelming saturation of rains from tropical storm Agatha. Not Photoshop, sadly: these happen from time to time during major storms in part because of unstable geology (and bad urban engineeringread more about it in the comments). There are rumors of similar sinkholes now forming nearby.
