Here is how I created a Tsunami Sound Effect from scratch. I don't recall seeing any Tsunamis in a video game so far, not even in Sim City's disaster mode, but who knows, this video might come in handy one day.
Before getting into to this, I know you game developers are looking for high quality sound effect. I recommend you check out my website: http://www.ogsoundfx.com
I also know a lot of you can't afford to purchase sound effects for your indie game that you put your heart and guts into developing. So here are a few ways to get a pretty nice collection of free SFX:
1. Subscribe to my Youtube Channel and get this for free: http://www.ogsoundfx.com/product/youtube-subscribers-pack/
2. Subscribe to my Newsletter and get 120MB of professional sound effects !
Enjoy the video !
