Three years after the storm in northern Chile, which caused several landslides in the regions of Antofagasta, Atacama, and Coquimbo (1) and little more than three months after the landslide that affected Villa Santa Lucía (2) in the southern part of the Los Lagos region, we analyzed the dynamic condition of construction in our country and how it has affected human settlements located in the path of increasingly common natural events.

Three years after the storm in the north of Chile that caused several landslides in the regions of Antofagasta, Atacama and Coquimbo (1) and little more than three months after the landslide that affected Villa Santa Lucía (2), in the sector south of the Los Lagos region, we reflect on construction in our restless territory. We consider how Chile’s dynamic condition has affected the human settlements that have found themselves in the path of geological events that are difficult though not impossible to foresee and perceived as increasingly habitual and destructive.

In the Infographic of this week, we show the scenario of Villa Santa Lucia after the landslide on December 16, 2017 whose magnitude can be understood through its more than 100 victims (2), and how this disaster has been framed in the national context. At the same time, we can see on the map on the left, the area attached to the Yelcho glacier that broke off as a flow of debris (3) after the torrential rains that fell between December 15 and 16 ( 4), and how the landslide, generated by this ice break, made its way to the town, cutting off the Austral Highway. The climatic event occurring in conjunction with the multiple geological conditions within this territorial framing, such as the Liquiñe-Ofqui fault (5), colluded in its outcome with the more than twenty landslides that have affected different localities of the country in the last thirty years (6). We can accuse the State of having a short memory and being accustomed to dealing with problems instead of anticipating them, but even in the 17th century, before the foundation and urban expansion of most of the affected localities, representations of Chile showed a geography crowned by volcanoes and mountains. Even then, important movements of land and water were observed (7). Without going farther back than 2008, just after the Chaitén volcano erupted, the National Geology and Mining Service of Chile (SERNAGEOMIN) described the specific geographical characteristics surrounding Villa Santa Lucia that indicated danger for this locality before the event occurred (8).
