Extinction-Level Events on Google Maps

Down 2 Earth is a meteor impact simulator that uses Google Maps to predict the impact of various sizes of meteor on the Earth.

Using the simulator you can enter a number of parameters, including the size  and density of the meteor and the angle of trajectory. To see the predicted results of your meteor's impact you then just need to click on the Google Map to view an overlay of the likely crater size.


Would I Survive a Nuke? is a little Google Maps application that allows you to see the likely effect of a nuclear bomb falling on any location.

The application allows you to select a location, the size of the bomb and view the likely effects of the bomb striking at your chosen location.

Ground Zero II is a similar application that includes more bomb choices and also includes a wind direction selector that will show you the likely fallout area of a nuclear bomb striking at a particular location.

NUKEMAP is another nuclear bomb effects calculator for Google Maps. The calculator allows the user to select a location on Google Maps and view the likely effects of a nuclear bomb on the surrounding area.

Tsunami Mapper makes use of the Google Maps elevation service and a flood fill algorithm to display the likely effects of a tsunami hitting the shore anywhere in the world.

The map allows you to enter a location and then set the parameters of a possible tsunami. These include the wave height, the direction of the wave to travel and the tsunami starting point. The map will then display the areas that are likely to be effected by water damage if such a tsunami hit your location.

Flood Map allows you to view the risk of flooding at any location in the world.

Using flood map you can set a water elevation height for any location and view the likely effects on a Google Map. Areas that are likely to be flooded are displayed on the map with a blue overlay.

It is also possible to right-click on any location and view the elevation level at that point. If you want to share a Flood Map search you can cut and paste a link to the current map view.
