Ok. (English is not my first language, sorry about any grammar mistakes)
So I decided to play a little with the possible outcome of a whale-sized meteor. ( Try yourself
Assuming a 65 ft (blue whales = 98 ft) iron/metallic asteroid and 11 km/s velocity (based on a little google research and considering a best case
scenario or a less damaging one) . Here are some results;
Energy before atmospheric entry: 2.03 x 1015 Joules = 484.32 KiloTons TNT
The average interval between impacts of this size somewhere on Earth is 169.6 years
The air blast will arrive approximately 30.6 seconds after impact.
Peak Overpressure: 9450 Pa = 0.0945 bars = 1.34 psi
Max wind velocity: 21.4 m/s = 47.9 mph
Sound Intensity: 80 dB (Loud as heavy traffic)
Glass windows will shatter.
I'm no specialist, but I REALLY don't think this is a meteor. The huge impact and sound blast would have draw a lot more attention.
