This video is riveting. It's a little over 25 minutes long, but it's worth watching. It starts with a view of what looks like a canal that has lost all its water. Around 3 minutes in, the water slowly starts flowing in. Then the boats in the canal start crashing into each other. People start running for higher ground. The water overflows the canal banks. Then what looks like an entire town comes floating by. Then the fires start. It's an amazing video. Warning: I got a little motion sick, so if you're prone to that, watch it a bit at a time.
