Because of heating if pressure cooker the pressure inside the cooler will increase and it can be blown only when heat supply is didn't switched off for more time
Based on that experience, and other experience with deliberately ruptured pressure vessels, I'd say that these are the features of a pressure cooker 'explosion':
1) Steam being generated at a faster rate than the pressure regulator can handle, possibly because the pressure regulator is obstructed by boiled-up food (quite possible);
2) A safety pessure release system that is also obstructed somehow (much less likely than 1) because the safety device is usually resistant to seizure, obstruction or other catastrophic 'breakage' - it is a simple plug or rupture disk, often combined with a small fusible plug);
