This tends to happen more with higher gravity beers and proper pitching rates. Next time use a blow off tube with recipe until after the kraeusen dies down and then put on the airlock.
Also make sure you can control the fermentation temperature if possible (keeping <70 F during first few days) as this will also help control the kraeusen volcano!
