Impact: Earth!

Gareth Collins, H. Jay Melosh and Robert Marcus

Impact: Earth! is a new, more visual and user-friendly update to our impact calculator, developed and hosted by Purdue University.

The original Earth Impact Effects Program is still available to calculate the effects a given distance from an impact. It uses exactly the same algorithms to estimate the impact effects.

You can also try out a version of the original program that is still under development 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!
