A horrifying virtual tool allows people to see how devastating the impact of a nuclear bomb would be.
As one of the world's atomic weapons super powers - Russia - invades Ukraine, fears about dangerous bombs are at the forefront of the public conscience.
Including estimations based on nuclear weapons currently in the Russian arsenal, NUKEMAP provides an insight to the mass destruction the world would face if a nuclear bomb was dropped.
The site allows you to enter a specific destination to find out exactly how and where things would be impacted.
Information including estimated fatalities, injuries such as third degree radiation burns, and building damage is explained using shaded area zones.
Expert Professor Alex Wellerstein came up with the idea using declassified nuclear weapons effects data.
Launching in 2012, the site has now has now carried out over 220million virtual detonations.
Here is what the site estimates if Edinburgh fell victim...
If dropped on Edinburgh
NukeMap estimates the fatalities and injuries caused if Topol (SS-25) - a nuclear bomb currently in Russian arsenal - was to be dropped on Edinburgh.
This bomb is an 800-kiloton device (800 kt).
The map states that a terrifying 241,680 people would be killed by the bomb with an additional 243,940 being injured by the blast.
Moderate blast damage - which would result in buildings collapsing, fire and widespread fatalities - reaches ground 6.53km (a huge 134km²) from the centre where the bomb is dropped.
With a fireball radius or 0.88km (2.45km²), the bomb is estimated to create a thermal radiation radius of 11.1km. Thermal radiation causes third degree burns, meaning anyone within the 11.1km of the dropped bomb would likely be severely injured.
If a Topol was dropped on the centre of Edinburgh, people are far away as Musselburgh, Dalkieth, Bonnyrigg, Penicuik, Balerno and the Pentland Hills would fall within the thermal radiation zone that fall within the orange shaded area.
As far out as 18.4km, there would likely still be considerable damage. This covers a massive 1,060km².
The map shows that injuries and damage to buildings - including smashed windows - occurs in the further out 'light blast damage radius', shown in the lighter grey outer circle.
