Hello Lister, I wonder what would happen if I was watching Meteorite Men and all of a sudden the show is interrupted by the emergency broad cast system.
Residence of SLC Utah a meteor the size of Manhattan with a diameter estimated to be about 3 miles has hit down town LA...... THIS IS WHAT COULD HAPPEN TO ME IN SLC UTAH. Your Inputs: Distance from Impact: 966.00 km ( = 600.00 miles ) Projectile diameter: 4.83 km ( = 3.00 miles ) Projectile Density: 2000 kg/m3 Impact Velocity: 35.00 km per second ( = 21.70 miles per second ) Impact Angle: 50 degrees Target Density: 2500 kg/m3 Target Type: Sedimentary Rock Energy: Energy before atmospheric entry: 7.22 x 1022 Joules = 1.72 x 107 MegaTons TNT The average interval between impacts of this size somewhere on Earth during the last 4 billion years is 4.1 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: Transient Crater Diameter: 44.5 km ( = 27.6 miles ) Transient Crater Depth: 15.7 km ( = 9.77 miles ) Final Crater Diameter: 73.3 km ( = 45.5 miles ) Final Crater Depth: 1.08 km ( = 0.669 miles ) The crater formed is a complex crater. The volume of the target melted or vaporized is 491 km3 = 118 miles3 Roughly half the melt remains in the crater, where its average thickness is 315 meters ( = 1030 feet ). Thermal Radiation: Time for maximum radiation: 2.38 seconds after impact Visible fireball radius: 10.1 km ( = 6.26 miles ) The fireball appears 2.37 times larger than the sun Thermal Exposure: 1.83 x 106 Joules/m2 Duration of Irradiation: 18 minutes Radiant flux (relative to the sun): 1.69 Seismic Effects: The major seismic shaking will arrive approximately 3.22 minutes after impact. Richter Scale Magnitude: 9.4 Mercalli Scale Intensity at a distance of 966 km: 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. V. Felt by nearly everyone; many awakened. Some dishes, windows broken. Unstable objects overturned. Pendulum clocks may stop. Ejecta: The ejecta will arrive approximately 8.07 minutes after the impact. At your position there is a fine dusting of ejecta with occasional larger fragments Average Ejecta Thickness: 3.89 cm ( = 1.53 inches ) Mean Fragment Diameter: 1.21 mm ( = 0.475 tenths of an inch Air Blast: The air blast will arrive approximately 48.8 minutes after impact. Peak Overpressure: 45800 Pa = 0.458 bars = 6.5 psi Max wind velocity: 91.5 m/s = 205 mph Sound Intensity: 93 dB (May cause ear pain) Damage Description: Multistory wall-bearing buildings will collapse. Wood frame buildings will almost completely collapse. Glass windows will shatter. Up to 90 percent of trees blown down; remainder stripped of branches and leaves.
