Early inhabitants along the hyperarid coastal Atacama Desert in northern Chile developed resilience strategies over 12,000 years, allowing these communities to effectively adapt this extreme environment, including impact of giant earthquakes and tsunamis. Here, we provide geoarchaeological evidence revealing a major tsunamigenic earthquake that severely affected prehistoric hunter-gatherer-fisher ~3800 years ago, causing an exceptional social disruption reflected contemporary changes...
Abstract A Late Holocene cliff‐top deposit of large boulders well above the limits modern storm waves is described from southern coast Atacama Desert (northern Chile). The largest moved boulder weighs >40 t and field data point to a flood height >18·5 m high tide level an inland penetration greater than 284 cliff edge. minimum flow velocity needed for particle entrainment was estimated as 10·1 ms −1 most likely processes sediment deposition different were deduced. distribution, sorting...
The last hydrometeorological extreme event that caused large floods in the southern Atacama Desert March 2015 raised concern about how little was known fluvial dynamic of these arid basins. Understanding response intermittent and ephemeral rivers drylands to present context global change is critical preserve ecological human systems they support, sustainably manage their scarce water resources develop flood risk management plans. We have studied instrumental historical record explored...
River mouths act as containers for pollution episodes that have occurred in their drainage basins over time. The estuary of the Tinto is currently one most polluted areas world, due to past and recent mining industrial activities. This communication studies concentrations seven strategic minerals a sediment core obtained middle this river. Holocene geochemical record has allowed us distinguish four contamination: an initial acid rock during MIS-1 transgression three anthropogenic ones first...
We analyze the role of low‐strength materials in potential structural instability related to volcano spreading at active Teide stratovolcano (Tenerife, Canary Islands). To study we took advantage a network large tunnels within volcano, excavated for water supply, which allows situ inspection and reconstruction both substratum structure. identified two factors are potentially important Teide's instability: 1) dipping breccia layer; 2) hydrothermally‐altered weak core inside volcano. Despite...
The ecological value of coastal wetlands is globally recognized, particularly as biodiversity hotspots, but also buffer areas because their role in the fight against climate change recent years. Most Chile’s are concentrated central and southern part country due to conditions. However, northern go unnoticed despite being located high water deficit (desert areas) bird migratory routes along north–south cordon South America. This study reviews current environmental status arid Chile (Lluta,...
Abstract. Chile is highly exposed to tsunami hazard from large earthquakes often occurring along the Peru–Chile trench, like 16 September 2015 event. However, only recently has been considered in land-use policies of Chilean coast. These new regulations must enforce identification most vulnerable sectors coastal cities. This paper analyses and validates two latest versions Papathoma Tsunami Vulnerability Assessment (PTVA) model reconstructed scenario cities La Serena Coquimbo. Both models...
The 22-23 April 2015 eruption of the Calbuco volcano (Southern Andes, Chile) led to extensive pyroclastic density currents (PDCs) interactions with vegetation. We seek describe PDCs which affected both Tepu and Frío rivers, northern Calbuco, from their timing deposition cooling erosion, as well impacts on forests. Our investigation is based field stratigraphy, forest disturbance assessment, geothermometry degassing pipes charcoal. These reached at least ~540-603 °C, estimated fumaroles,...
This short paper analyses the concentrations of two major components (Fe, S) and eight trace elements (As, Au, Co, Cu, Hg, Ni, Mn, Zn) in soils tailings from Tierra Amarilla (northern Chile) using ICP-Ms analysis. The levels As, Fe S are very high come polymetallic sulphides nearby mines, together with minor contributions Ni Mn. Hg has its origin extreme seasonal flows Copiapó River, which erodes dumps old precious metal mines. These require further analysis possible immobilisation...
Abstract On 16 September 2015, the Mw 8.3 Illapel megathrust earthquake broke subduction contact of Nazca plate beneath South American plate, causing unexpectedly high tsunami waves that strongly impacted coast along Coquimbo region in central–northern Chile. Here, we report results from a postearthquake and survey, evidencing complex coastal geological response driven by near trench seismic patches ruptured during this event. Systematically, run-ups, up to 10–11 m a.s.l., were measured on...
Estuaries are excellent environments for identifying pollution episodes that have affected river basins, as their sediments the final destination of some pollutants. This paper studies geochemical evolution five elements (As, Co, Cu, Pb, Zn) in a core extracted from middle estuary Tinto River (SW Spain). The results based on facies interpretation, ICP atomic emission spectrometry analysis, application regional background to obtain geoaccumulation index and dating. main objective this...
