Op 50 km van de inslag, uitgaande van een projectiel van 1km diameter, dichtheid van 3000 kg/m3, een snelheid van 25.00 km/s, inslaand op land (of ondiep water) zijn de gevolgen:
WarmtestralingTime for maximum radiation: 0.632 seconds after impact
Visible fireball radius: 15.5 km = 9.65 miles
The fireball appears 70.6 times larger than the sun
Thermal Exposure: 9.14 x 107 Joules/m2
Duration of Irradiation: 204 seconds
Radiant flux (relative to the sun): 447
Effects:Clothing ignites
Much of the body suffers third degree burns
Newspaper ignites
Plywood flames
Deciduous trees ignite
Grass ignites
Aardbeving:The major seismic shaking will arrive at approximately 10 seconds.
Richter Scale Magnitude: 8.0
Mercalli Scale Intensity at a distance of 50 km:IX. General panic. Damage considerable in specially designed structures; well-designed frame structures thrown out of plumb. Damage great in substantial buildings, with partial collapse. Buildings shifted off foundations. Serious damage to reservoirs. Underground pipes broken. Conspicuous cracks in ground. In alluviated areas sand and mud ejected, earthquake fountains, sand craters.
X. Most masonry and frame structures destroyed with their foundations. Some well-built wooden structures and bridges destroyed. Serious damage to dams, dikes, embankments. Large landslides. Water thrown on banks of canals, rivers, lakes, etc. Sand and mud shifted horizontally on beaches and flat land. Rails bent slightly.
BrokstukkenThe ejecta will arrive approximately 101 seconds after the impact.
Mean Fragment Diameter: 78.6 cm = 31 inches
DrukgolfThe air blast will arrive at approximately 152 seconds.
Peak Overpressure: 669000 Pa = 6.69 bars = 94.9 psi
Max wind velocity: 607 m/s = 1360 mph (2185 km/uur)
Sound Intensity: 117 dB (May cause ear pain)
Effects:Multistory wall-bearing buildings will collapse.
Wood frame buildings will almost completely collapse.
Multistory steel-framed office-type buildings will suffer extreme frame distortion, incipient collapse.
Highway truss bridges will collapse.
Highway girder bridges will collapse.
Cars and trucks will be largely displaced and grossly distorted and will require rebuilding before use.
Up to 90 percent of trees blown down; remainder stripped of branches and leaves.
Met slechts 3,8 miljoen koeien in Nederland zou het aantal menselijke slachtoffers hoger kunnen liggen dan het aantal dode koeien
