Implementation of the destruction of the landscape, for example, the game Scorched Earth on iphone or Java

Question

I am looking for an example of how to implement 2D terrain destruction that you see in games like scorched earth or on the iPhone iShoot .

I'm looking for an implementation of a game that needs to make a destructible terrain and render it using OpenGL (LWJGL in Java) and use OpenGL ES on the iPhone.
