2007_Carancas_impact_event

The Carancas impact event refers to the fall of the Carancas chondritic meteorite on September 15, 2007, near the village of Carancas in Peru, close to the Bolivian border and Lake Titicaca. The impact created a small crater in the clay soil and scorched earth around its location. A local official, Marco Limache, said that "boiling water started coming out of the crater, and particles of rock and cinders were found nearby", as "fetid, noxious" gases spewed from the crater. Surface impact occurred above 3,800 metres (12,500 ft).
After the impact, villagers who had approached the impact site grew sick from a then-unexplained illness, with a wide array of symptoms. Two days later, Peruvian scientists confirmed that there had indeed been a meteorite strike, quieting widespread speculation that it might have been a geophysical rather than a celestial event. At that point, no further information on the cause of the mystery illness was known. The ground water in the local area is known to contain arsenic compounds, and the illness is now believed to have been caused by arsenic poisoning incurred when residents of the area inhaled the vapor of the boiling arsenic-contaminated water.
