The Curuçá River event, 'Brazil's Tunguska'
On the morning of 13 August 1930, people near the Curuçá river in western Amazonas reported a red sun, falling fireballs and explosions that shook the forest, possibly an airburst of a meteoroid.

The account
A Capuchin friar, Fedele d'Alviano, collected accounts days later; his report was published in L'Osservatore Romano in 1931 and rediscovered by astronomer Mark Bailey in 1995.
The sceptical view
It rests on one investigator's account. A circular feature found on satellite images was later shown not to be an impact crater.
