Ecuador: Increased volcanic activity at Sangay Volcano in Morona Santiago Province as of Nov. 8
Increased volcanic activity at Sangay Volcano, Ecuador, as of Nov. 8. Reports of ashfall in Chimborazo and Morona Santiago provinces.
Event
Officials at Ecuador's Geophysical Institute (IG) have observed increased levels of volcanic activity at the Sangay Volcano, located approximately 52 km (32 miles) southeast of Riobamba, as of Nov. 8. The volcano has been in its current eruptive phase since May 2019 and during the latest eruptive episode Nov.7 and early Nov. 8 a large cloud of volcanic ash and gases has been observed reaching 870 meters (2,854 feet) above the crater. The eruption has dispersed a large ash cloud in a westerly direction from the crater, and the institute has warned ashfall is likely in parts of Chimborazo and Morona Santiago provinces. The ashfall could extend further west and reach parts of Los Rios, Guayas, and Bolivar provinces in the coming hours.
Due to the threat of ashfall, authorities suspended classes at schools in Chambo, Riobamba, Guano, Guamote, Chunchi, and Alausi cantons of Chimborazo Province Nov. 7. Despite the increased volcanic activity, authorities have not issued any mandatory evacuations for the surrounding area and the alert level for the volcano has not been raised. 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 central Ecuador. 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 Sangay 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.
