1930 Curuçá River event[edit]

On August 13, 1930 the area near latitude 5° S and longitude 71.5° W experienced a meteoric air burst, also known as the Brazilian Tunguska event.[2][3] The mass of the meteorite was estimated at between 1,000 and 25,000 tons, with an energy release estimated between 0.1 and 5 megatons, significantly smaller than the Tunguska Event.[2][3][4][5]
