Explosion crater calculator. Calculate the blast radius and effects of explosions using validated scaling laws (Taylor-Sedov) and empirical data (Kingery curves). The Tunguska event was a large explosion of between 3 and 50 megatons TNT equivalent [2] that occurred near the Podkamennaya Tunguska River in Yeniseysk Governorate (now Krasnoyarsk Krai), Russia, on the morning of 30 June 1908. Internet Explorer 9+ Firefox Chrome NUKEMAP is a website for visualizing the effects of nuclear detonations. You can choose either to compute crater size from the projectile size, or to compute the projectile size from the crater size. Click on the map to fire your meteor then evaluate the scale of destruction at your chosen destination with the “ Crater Depth ” and “ Data View ” tabs at the bottom of the screen. Click the map to place the crater Go back Data view Crater depth Crater size. Please enter values in the boxes below to describe your impact event of choice and your distance away. 72a and b for a 1-kiloton explosion in four media. The Impact Calculator will also give you an estimate of of how likely a meteor with your chosen properties is likely to hit the Earth! NUKEMAP, created by Alex Wellerstein, a nuclear historian, allows people to explore the blast radius of a nuclear bomb anywhere in the world. Users can select the smallest bomb ever designed, all the way up to the largest, and see what the fallout would be. hhak cvks sqiu esmad nopwv bjqk hekostje zihuu ngjdnl xuhuyk
