Láscar

 

Láscar volcano, a stratovolcano in the Andes Mountains, is one of the most active volcanoes in northern Chile. It has six summit craters and frequently produces small-to-moderate explosive eruptions, with occasional larger ones that send ash columns high into the atmosphere. The volcano’s activity stems from the subduction of tectonic plates, which creates the magma that feeds its eruptions. Láscar is constantly releasing volcanic gases and has intermittent explosive episodes, posing a hazard to nearby communities and air travel.

Láscar’s Eruptive History

Year Eruption Activity
1848 First recorded eruption in historical times. Likely a moderate Vulcanian explosion, though specific details are limited.
1854 Significant explosive eruption, possibly Vulcanian in style, with ashfall reported in surrounding areas, impacting local settlements.
1900 Moderate Vulcanian eruption with ash emissions and possible pyroclastic flows.
1933 Explosive eruption, likely Vulcanian, with ashfall reaching over 200 km from the volcano, affecting wider regions and potentially disrupting transportation.
1951 Small Vulcanian eruption with ash emissions and limited impact on surrounding areas.
1960 Moderate Vulcanian eruption with significant ashfall and pyroclastic flows, potentially causing damage to infrastructure and disrupting local communities.
1963 Small Vulcanian eruption with ash emissions and limited impact.
1964 Moderate Vulcanian eruption with ash emissions and possible pyroclastic flows, impacting local areas.
1969 Small Vulcanian eruption with ash emissions and limited impact.
1972 Moderate Vulcanian eruption with ash emissions and possible pyroclastic flows, affecting local areas.
1984 Small Vulcanian eruption with ash emissions, marking the start of a period of increased activity at Láscar.
1986 Significant Vulcanian eruption with ashfall reaching Argentina, demonstrating the potential for widespread impact from Láscar’s eruptions.
1990 Moderate Vulcanian eruption with ash emissions and possible pyroclastic flows, affecting local areas.
1993 Major Plinian eruption: Láscar’s largest historical eruption, with a Plinian column reaching 23 km in height. Significant ashfall occurred over a wide area, causing disruption to air travel across South America and impacting local communities. Pyroclastic flows and lahars likely occurred.
1994 Moderate Vulcanian eruption with ash emissions and possible pyroclastic flows, following the major 1993 eruption.
1995 Small Vulcanian eruption with ash emissions and limited impact.
2000 Moderate Vulcanian eruption with ash emissions and possible pyroclastic flows, affecting local areas.
2005 Small Vulcanian eruption with ash emissions and limited impact.
2006 Moderate Vulcanian eruption with ashfall reaching over 100 km from the volcano, demonstrating the continued potential for widespread ashfall.
2013 Small Vulcanian eruption with ash emissions and limited impact.
2015-2017 Period of increased activity with persistent gas emissions, occasional ash venting, and small explosions, indicating unrest within the volcano.
2022 Moderate Vulcanian eruption with an ash plume reaching 6 km in height. Pyroclastic flows were generated, posing a significant hazard to the surrounding area.
2023 Ongoing activity with gas-and-steam emissions and occasional ash venting, suggesting continued unrest and the potential for future eruptions.
