I suppose it paved the way for a Calamity.
Also, nobody said that a Calamity suddenly happens in seconds (even if it can last long past that). Take the Great Flood for example, it didn't happened in a matter of minutes. People had limited time to prepare. I took time to just come, and happen.
With that in mind you could perfectly argue that Silvertears was just the beginning. After all Bahamut happened in a matter of mere sennights past that if i'm not mistaken.
