I think the reason Twilight "inexplicably" became powerful was that she was already powerful ,but didn't know how to release it (as evidenced earlier in the episode, when she was studying). The explosion merely startled her, causing a "flood" of magical energy to be expelled. The gentle touch of another pony, Princess Celestia, calmed her down enough to stop the chaos. That's just my take on it, however.
