I found this interactive web site the other day, and thought it was a great tool for any aspiring Doomsayer
Its called Earth Impact Effects Program. Basically you punch in the details of an asteroid or comet that is on a collision course with earth, velocity, density/material its composed of, angle of entry, size, ocean or land strike, you can even set the depth of the ocean it will land in. It then calculates the data into environmental consequences of your object. seismic impact, size of the crater, enviromental effects, tsunami height ect. Its a lot of fun to play around with, here is one I made for elenin hitting the ocean................3000ft tsunami

Tool:impact.ese.ic.ac.uk...

Distance from Impact: 300.00 km ( = 186.00 miles )
Projectile diameter: 5.00 km ( = 3.11 miles )
Projectile Density: 1000 kg/m3
Impact Velocity: 50.00 km per second ( = 31.10 miles per second )
Impact Angle: 45 degrees
Target Density: 1000 kg/m3
Target Type: Liquid water of depth 3.7 km ( = 2.3 miles ), over crystalline rock.
Energy:
Energy before atmospheric entry: 8.18 x 1022 Joules = 1.95 x 107 MegaTons TNT
The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 4.5 x 107years
Major Global Changes:
The Earth is not strongly disturbed by the impact and loses negligible mass.
The impact does not make a noticeable change in the tilt of Earth's axis (< 5 hundreths of a degree).
The impact does not shift the Earth's orbit noticeably.
Crater Dimensions:

The crater opened in the water has a diameter of 65.9 km ( = 40.9 miles ).
For the crater formed in the seafloor:
Transient Crater Diameter: 21.9 km ( = 13.6 miles )
Transient Crater Depth: 7.76 km ( = 4.82 miles )
Final Crater Diameter: 33 km ( = 20.5 miles )
Final Crater Depth: 847 meters ( = 2780 feet )
The crater formed is a complex crater.
The volume of the target melted or vaporized is 32.3 km3 = 7.75 miles3
Roughly half the melt remains in the crater, where its average thickness is 85.5 meters ( = 280 feet ).

Time for maximum radiation: 1.74 seconds after impact
Visible fireball radius: 79.6 km ( = 49.4 miles )
The fireball appears 60.3 times larger than the sun
Thermal Exposure: 3.86 x 108 Joules/m2
Radiant flux (relative to the sun): 343

Clothing ignites
Much of the body suffers third degree burns
Newspaper ignites
Plywood flames
Deciduous trees ignite
Grass ignites

Seismic Effects:
The major seismic shaking will arrive approximately 60 seconds after impact.
Richter Scale Magnitude: 8.7
Mercalli Scale Intensity at a distance of 300 km:

VII. Damage negligible in buildings of good design and construction; slight to moderate in well-built ordinary structures; considerable damage in poorly built or badly designed structures; some chimneys broken.

VIII. Damage slight in specially designed structures; considerable damage in ordinary substantial buildings with partial collapse. Damage great in poorly built structures. Fall of chimneys, factory stacks, columns, monuments, walls. Heavy furniture overturned.

Ejecta:

The ejecta will arrive approximately 4.24 minutes after the impact.
At your position there is a fine dusting of ejecta with occasional larger fragments
Average Ejecta Thickness: 7.66 cm ( = 3.01 inches )
Mean Fragment Diameter: 1.17 cm ( = 0.462 inches )

Air Blast:

The air blast will arrive approximately 15.2 minutes after impact.
Peak Overpressure: 554000 Pa = 5.54 bars = 78.7 psi
Max wind velocity: 545 m/s = 1220 mph
Sound Intensity: 115 dB (May cause ear pain)
Damage Description:

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.
Glass windows will shatter.
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.

Tsunami Wave:

The impact-generated tsunami wave arrives approximately 26.4 minutes after impact.
Tsunami wave amplitude is between: 408.0 meters ( = 1340.0 feet) and 815.0 meters ( = 2670.0 feet).

The only part you need to know is this:

Clothing ignites
Much of the body suffers third degree burns

Everything else is ancillary. If you burn, you will no longer want to live, or will die a painful death shortly after.

Thats only at 300km distance, I find the near 3000ft tsunami and 1200mph winds more interesting

You wouldn't find them interesting for very long though if you were anywhere near those effects.

Thanks for that just been running some numbers from theRSOE EDIS , To see what potential real impacts would be like at several distances from where i live.
Quite reassuring to know that actual damage is most realistically going to be broken windows if an average say 500M NEO hit at a reasonably fast 15kms 70 miles away.
The likelihood of an objecting hitting this close considering the size of the earth and the size of the NEO is probably quite small ,
However it would have to land somewhere best to warn people you'd only have to evacuate maybe a 200 mile radius or alternatively low lying areas.
Danger from space has been relegated in my priority's to "Nothing to worry about" it'll only smash my windows at worst more than likely."
