Abstract: 
We describe various aspects of a comprehensive modeling study of the processes induced in all geospheres the meteoroid passed and exploded over Romania on January 7, 2015.  We estimated turbulence generation, magnetic, electric, electromagnetic, and seismic effects, the effects of acoustic-gravity waves, and ionospheric effects. The passage of the meteoroid has caused the formation of a plasma trail and an appreciable disturbance not only in the lower but also in the upper atmosphere at the distances not less than 1,000 km. The magnitudes of plasma, magnetic, electric, electromagnetic, and acoustic effects were significant. The magnitude of the earthquake caused by the meteoroid explosion did not exceed 1. The mean rate of the fall of cosmic bodies similar to the Romanian meteoroid is equal to 8.4 times a year.
Keywords: gas-dust plume, gas-dynamic and thermal effects, interaction with atmosphere, mechanical, meteoroid, optical
