Your Inputs:
Distance from Impact: 60.00 km = 37.26 miles
Projectile Diameter: 6000.00 m = 19680.00 ft = 3.73 miles
Projectile Density: 8000 kg/m3
Impact Velocity: 50.00 km/s = 31.05 miles/s
Impact Angle: 60 degrees
Target Density: 2500 kg/m3
Target Type: Sedimentary Rock
Energy:
Energy before atmospheric entry: 1.13 x 1024 Joules = 2.70 x 108 MegaTons TNT
The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 3.4 x 108years
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 Earth's rotation period or the tilt of its axis.
The impact does not shift the Earth's orbit noticeably.
Crater Dimensions:
What does this mean?

Transient Crater Diameter: 102 km = 63.4 miles
Transient Crater Depth: 36.1 km = 22.4 miles

Final Crater Diameter: 187 km = 116 miles
Final Crater Depth: 1.43 km = 0.888 miles
The crater formed is a complex crater.
The volume of the target melted or vaporized is 8710 km3 = 2090 miles3
Roughly half the melt remains in the crater , where its average thickness is 1.06 km = 0.661 miles
Thermal Radiation:
What does this mean?

Time for maximum radiation: 4.17 seconds after impact

Your position is inside the fireball.
The fireball appears 788 times larger than the sun
Thermal Exposure: 1.50 x 1011 Joules/m2
Duration of Irradiation: 2710 seconds
Radiant flux (relative to the sun): 55300

Effects of Thermal Radiation:

Clothing ignites

Much of the body suffers third degree burns

Newspaper ignites

Plywood flames

Deciduous trees ignite

Grass ignites

Seismic Effects:
What does this mean?

The major seismic shaking will arrive at approximately 12 seconds.
Richter Scale Magnitude: 10.2 (This is greater than any earthquake in recorded history)
Mercalli Scale Intensity at a distance of 60 km:

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.

XI. As X. Rails bent greatly. Underground pipelines completely out of service.

Ejecta:
What does this mean?

The ejecta will arrive approximately 111 seconds after the impact.
Your position is beneath the continuous ejecta deposit.
Average Ejecta Thickness: 4490 m = 14700 ft

Air Blast:
What does this mean?

The air blast will arrive at approximately 182 seconds.
Peak Overpressure: 1.55e+08 Pa = 1550 bars = 22000 psi
Max wind velocity: 10000 m/s = 22400 mph
Sound Intensity: 164 dB (Dangerously Loud)
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.

Gott, sei Dank passiert sowas nur alle 3,4*10^8 Jahre.;)

Is tschon irgendwie lustig auszurechnen, was so alles passiert ...

Ja. Ich hoffe jedenfalls nicht, dass uns demnächst ein Eisenklumpen mit einem Durchmesser von sechs Kilometern trifft

Und was hat der gemacht? Hat der ein Kaninchen erschlagen?

Naja, ich wollte halt mal übertreiben. Muss doch auch mal sein

Mich würde mal interessieren, was für ein Teil da angeflogen kommen muß, damit die Erde "strongly disturbed" wird...

Rainer Calmund?

Man könnte auch den Mond au die Erde stürzen lassen.

Zitat von Reg

ich habs mal gemacht....die erde komplett pulverisiert, 80000t Eisen im winkel von 90° und 1km/s *hrhr*

Geil.

Ja. Das macht einen Riesenspass!
Normale Steinsbrocken mit weniger als 80 Meter Durchmesser zerbrechen in der Atmosphäre und sind ungefährlich. 85m große erzeugen "nur" einen ca. 1,5km Krater. Aber ein 83m Komet explodiert kanpp über der Erdoberfläche und macht alles im Umkreis von 15 km kaputt. Huiiii, ein Riesenspass!
