It's most likely related to "nucleation" and is because of extra sediment carried over. CO2 loves to form on particles or imperfections of any kind, and if there are particles in the bottles, this can cause gushers.
You could pop all the caps and recap to remove some of the carbonation.
Or every time you want to pop one of these, pour it into a pitcher to allow the foam to die down, then transfer to a glass for easier drinking with less foam.
It happens. To avoid it in future, just try to keep any sediment out of the bottles as much as humanly possible.
