Through its history, Chile was regularly affected by droughts. In the more arid parts of Chile droughts are produced when there are low amounts of snow accumulation in the Andes.[1] Chilean coastal drainage basins without snow accumulation are particularly vulnerable to drought.[1]
The territory of Central Chile has been affected by long-term droughts in 1280–1450, 1570–1650, 1770–1820 and 2010–present.[2][3]
