Impact: Earth - Ein nettes Tool zur Simulation der Zerstörung der Erde.
12.09.2011 um 20:45Ich habe ein schönes Tool gefunden, welches den Einschlag eines Meteoriden symoliert.
Man kann damit auch die Zerstörung der Erde symolieren. :D
Zeigt eure Einschläge her.

Beispiel:
Your Inputs:
Distance from Impact: 10000.00 km ( = 6210.00 miles )
Projectile diameter: 100.00 meters ( = 328.00 feet )
Projectile Density: 3000 kg/m3
Impact Velocity: 20.00 km per second ( = 12.40 miles per second )
Impact Angle: 45 degrees
Target Density: 1000 kg/m3
Target Type: Liquid water of depth 5.0 km ( = 3.1 miles ), over crystalline rock.
Energy:
Energy before atmospheric entry: 3.14 x 1017 Joules = 7.50 x 101 MegaTons TNT
The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 6.0 x 103years
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.
Atmospheric Entry:
The projectile begins to breakup at an altitude of 56600 meters = 186000 ft
The projectile reaches the ground in a broken condition. The mass of projectile strikes the surface at velocity 7.74 km/s = 4.81 miles/s
The impact energy is 4.71 x 1016 Joules = 1.12 x 101MegaTons.
The broken projectile fragments strike the ground in an ellipse of dimension 0.815 km by 0.576 km
Crater Dimensions:
What does this mean?
The crater opened in the water has a diameter of 1.98 km ( = 1.23 miles ).
For the crater formed in the seafloor:
The result of the impact is a crater field, not a single crater. The following dimensions are for the crater produced by the largest fragment.
Transient Crater Diameter: 719 microns ( = 28.3 thousandths of an inch )
Transient Crater Depth: 254 microns ( = 10 thousandths of an inch )
Final Crater Diameter: 899 microns ( = 35.4 thousandths of an inch )
Final Crater Depth: 191 microns ( = 7.54 thousandths of an inch )
The crater formed is a simple crater
The floor of the crater is underlain by a lens of broken rock debris (breccia) with a maximum thickness of 88.7 microns ( = 3.5 thousandths of an inch ).
At this impact velocity ( < 12 km/s), little shock melting of the target occurs.
Thermal Radiation:
What does this mean?
At this impact velocity ( < 15 km/s), little vaporization occurs; no fireball is created, therefore, there is no thermal radiation damage.
Seismic Effects:
What does this mean?
The Richter Scale Magnitude for this impact is less than zero; no seismic shaking will be felt.
Ejecta:
What does this mean?
Most ejecta is blocked by Earth's atmosphere
Air Blast:
What does this mean?
The air blast will arrive approximately 8.42 hours after impact.
Peak Overpressure: 12.2 Pa = 0.000122 bars = 0.00173 psi
Max wind velocity: 0.0287 m/s = 0.0643 mph
Sound Intensity: 22 dB (Easily Heard)
Tsunami Wave:
What does this mean?
The impact-generated tsunami wave arrives approximately 35.3 hours after impact.
Tsunami wave amplitude is less than 10 cm at your location.
