Impact: Earth!

Gareth Collins, H. Jay Melosh and Robert Marcus

The Earth Impact Effects Program calculates the environmental effects a given distance from an impact on Earth.

You can also try out a version of the original program to map the effects of an impact somewhere on Earth

In addition you can see all the slow-motion impacts we've performed as part of Impact Earth! below!
