Chile: Increased volcanic activity reported at Lascar volcano in Antofagasta Region as of Jan. 30
Increased volcanic activity ongoing at Lascar volcano in Antofagasta Region, Chile, as of Jan. 30. Authorities raise alert level.
Event
Officials with the National Geology and Mining Service of Chile (SERNAGEOMIN) have observed increased levels of volcanic activity at the Lascar volcano in Antofagasta, located approximately 160 km (99 miles) southeast of Calama, as of Jan. 30. Monitoring stations at the volcano have detected increased seismic activity since Jan. 27, including a magnitude-3.2 tremor, indicating an explosive eruption may be imminent at the volcano. Due to the increased activity, SERNAGEOMIN has raised the alert level at the volcano to orange (the third of four levels). Authorities have increased the security perimeter around Lascar from 5 km (3 miles) to 10 km (6 miles). Authorities may issue new alerts, or update/rescind existing advisories, as conditions change over the coming days. Additional eruptions could cause low-level seismic activity, ash clouds, and landslides in the surrounding area.
Air quality could become a concern, particularly in areas near the crater following an explosive event. Individuals in the region - especially those with underlying pulmonary conditions such as asthma, Chronic obstructive pulmonary disease (COPD), or lung cancers - may experience difficulty breathing and could suffer from lower tolerance to physical exertion.
Transport
Plan for possible transport disruptions in the surrounding area, especially if a significant eruptive event occurs. Road conditions could quickly deteriorate during periods of significant ashfall, and visibility could be reduced. Officials might close roads near the volcano, depending on the presence of hazardous volcanic material. Fine particulate matter ejected from the volcano could pose a hazard to flights in the surrounding airspace, including El Loa Airport (CJC) in Calama. Authorities may temporarily close airport facilities if significant ashfall accumulations occur.
Advice
Confirm flights if a large eruption occurs. Plan for possible transportation disruptions if operating near Lascar in the coming days. Seek updated information on road conditions before driving; due to reduced visibility, drive cautiously in areas affected by ash. Carry facemasks and observe other precautions to avoid ash inhalation if operating in the affected area.
