Guatemala: Increased activity at the Santa Maria-Santiaguito volcanic complex in Quetzaltenango, as of Jan. 30

Event

Increased levels of volcanic activity have been reported at the Santa Maria-Santiaguito volcanic complex in Quetzaltenango Department, as of Jan. 30. Ashfall has impacted several communities, particularly southwest of the site, since Jan. 29. Officials have recommended restricting travel near the impact site. A 5km (3 miles) exclusion zone is reportedly in effect. Eruptions could cause low-level seismic activity, ash clouds, and landslides in the surrounding area.

Health
Further volcanic activity may impact air quality. 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
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 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 the site over 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.
