El Salvador: Increased volcanic activity at San Miguel Volcano in San Miguel Department as of Nov. 16

Increased volcanic activity at San Miguel Volcano in El Salvador as of Nov. 16. Possible health concerns and traffic disruptions.

Warning

Event

Officials at El Salvador's Directorate General of Civil Protection have observed increased levels of volcanic activity at the San Miguel Volcano (known as Chaparrastique in El Salvador) in San Miguel Department, approximately 15 km (9 miles) southwest of the city of San Miguel, as of Nov. 16.

The volcano has been in its current active phase since December 2013. Due to the recent eruptions, authorities have issued a warning for San Miguel and Usulutan departments, particularly in the municipalities of Chinameca, San Jorge, and San Rafael Oriente, and established evacuation routes and temporary shelters as a precaution. Health concerns are likely due to emitted gasses, while traffic disruptions are possible. Authorities recommend avoiding activity near the volcano through at least Nov. 19.

Despite the increased volcanic activity, authorities have yet to issue mandatory evacuations for the surrounding area or raise the volcano's alert level. Additional eruptions could cause low-level seismic activity, ash clouds, and landslides in the surrounding area.

Health
Further volcanic activity may impact air quality in eastern El Salvador. 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
Transport disruptions in the surrounding area are possible, 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. Authorities might temporarily close airport facilities if significant ashfall accumulations occur.

Advice

Confirm flights. Plan for possible transportation disruptions if operating near the San Miguel Volcano in the coming days. Seek updated information on road conditions before driving; due to reduced visibility, drive cautiously in areas affected by ash. Carry masks or face coverings and observe other precautions to avoid ash inhalation if operating in the affected area.
