The loud sky event occurred at 9.25 pm (local time) and generated much fear among residents of this city situated on the Atlantic coast.
After the major meteor events over Finland, Brazil, the USA and Canada, now it's the turn of Argentina to be shaken by a meteor sonic boom.
According to witnesses, the blue-green bolide crossed the sky on fire and created a strong rumble as it suddenly disappeared in a bright flash of light.
The strong tremor was most probably linked to the sonic boom, as the space rock entered the Earth's atmosphere.
Here is a video of this loud and bright fireball exploding over Argentina:
The rumble in the video is like the so-called 'trumpets in the sky'.
