1994 Cando event
The Cando event was a bolide explosion that occurred in the village of Cando, Galicia, Spain, in the morning of January 18, 1994 at 7:15 UT. There were no reported casualties in this incident as the event was approximately 1,000 times less energetic than the Tunguska event.
Witnesses claim to have seen a fireball in the sky lasting for almost one minute. A possible explosion site was established when a local resident called the University of Santiago de Compostela to report an unknown gouge in a hillside close to the village. Up to 200 m³ of terrain was missing and trees were found displaced 100 m down the hill.
Opinions are divided about the causes of the explosion. Zdeněk Ceplecha of the Ondřejov Observatory in the Czech Republic explains the incident might have been a blast of subterranean gases which, removing the topsoil in a sudden explosion, vented into the air. The convective action of such a rising plume would create an electric charge separation sufficient to ignite the gases, accounting for the fireball-like observations. The same explanation has been circulated about the Tunguska event, against the more accepted meteor theory. Local residents, however, claim it was a meteor, as an object "the size of a full moon" was seen in the skies of the Spanish region of Galicia. The mystery became fertile ground for conspiracy theories that point to military or "alien activities".
