NOTA DEL BLOG:ACTUALIZACION :vean despues de que el meteorito pasa biene la BOMBA SONICA. ES LA QUE DAÑÓ E HIRIÓ A 1000 PERSONAS
300 EDIFICIOS DE TOTA LA CIUDAD HAN QUEDADOS AFECTADOS POR EL METEORITO
HUBO PERSONAS HERIDAS CON LOS VIDRIOS ROTOS (HERIDOS LEVES 1000 APROX,
*******************************************************
The big picture
There are several back-of-the-envelop estimates of the size and mass of the body but roughly the bolid had a diameter of 15m, a Mass of 7,000 tons (assuming a rocky density of 3 g/cc) . NASA scientists claim that the explosion was due to the largest rock crashing on the planet since Tunguska in 1908 (energy 10-15 MegaTons of TNT equivalent). Peter Brown, from University of Western Ontario determined a total energy of 300 kilotons of TNT equivalent for the Russian meteor, so ~20 Hiroshima bombs. It was larger than the Oct 2009 Indonesia event (50 kTons TNT eq) and Sikhote-Alin fall (Feb 1947, 10 kTons TNT eq). Interestingly, based on the statistical study of near-Earth asteroid population, we can estimate that a #RussianMeteor-like event should happen every ~30 years.
