Want to know what would happen if a 10km-wide asteroid came out of the sky and slammed down on your city?
Scientists at Purdue University and Imperial College London have updated their popular impact effects calculator first produced in 2004.
Users dial in details about the hypothetical impactor, like its diameter and density.
The web program then estimates the scale of the ensuing disaster, such as the size of the crater left behind.
It will also tell you how far away you need to be to avoid being buried by all the material thrown out by the blast, or set on fire.

Can it calculate where this rocket scientist is and land on him?.....

Earth-shattering kaboom ping.

I’m surprised this isn’t an iphone app.

I did a model run for a rocky meteor about the size of the Empire State building, traveling at 40 kilometers a second impacting at a 45 degree angle 200 miles of the coast in 2,000 feet of water:
The impact-generated tsunami wave arrives approximately 34.9 minutes after impact. Tsunami wave amplitude is between: 21.6 meters ( = 70.9 feet) and 43.3 meters ( = 142 feet).

The air blast from one of these things is impressive. A 1.3km diameter impactor on land creates a 900 mph+ blast a 100 miles away. Whoa!
