On September, 15th, 2007, close to noon local time, a bright fireball was observed and heard in the southern shore of the Lake Titicaca, close to the border between Peru and Bolivia (see map in Fig. 1). Many peasants and residents of the town of Desaguadero (Peru) and Guaqui (Bolivia) observed the fireball from East to West. The peasants of the Com-munity of Carancas, 10km south of Desaguadero, that were watching out their llamas and alpacas, heard a big explosion and observed the formation of a mush-room cloud. Minutes after, in the point of explosion, they found a ~15m hole in the terrain, half filled by underground water, and a lot of dispersed blocks of soils of sizes over a meter. Some pieces of a grayish material were found, clearly distinct from the sedimen-tary rocks of the terrain (molasses or red beds).
