>Your Inputs:
>Distance from Impact: 5000.00 km = 3105.00 miles

>Projectile Density: 3000 kg/m3
>Impact Velocity: 30.00 km/s = 18.63 miles/s
>Impact Angle: 30 degrees
>Target Density: 2500 kg/m3
>Target Type: Sedimentary Rock
>Energy:
>Energy before atmospheric entry: 7.07 x 1023 Joules = 1.69 x 108 MegaTons TNT
>The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 2.4 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.

>What does this mean?
>Transient Crater Diameter: 72.9 km = 45.3 miles
>Transient Crater Depth: 25.8 km = 16 miles
>Final Crater Diameter: 128 km = 79.5 miles
>Final Crater Depth: 1.28 km = 0.792 miles
>The crater formed is a complex crater.
>The volume of the target melted or vaporized is 3140 km3 = 753 miles3
>Roughly half the melt remains in the crater , where its average thickness is 752 meters = 2470 feet
>Thermal Radiation:
>What does this mean?
>The fireball is below the horizon. There is no direct thermal radiation.
>Seismic Effects:
>What does this mean?

>The major seismic shaking will arrive at approximately 1000 seconds.

>III. Felt quite noticeably by persons indoors, especially on upper floors of buildings. Many people do not recognize it as an earthquake. Standing motor cars may rock slightly. Vibrations similar to the passing of a truck.
>IV. Felt indoors by many, outdoors by few during the day. At night, some awakened. Dishes, windows, doors disturbed; walls make cracking sound. Sensation like heavy truck striking building. Standing motor cars rocked noticeably.

Was heiter stimmt!:-)
