Indonesia: Volcanic activity at Mount Merapi Volcano, Jan. 7-8
Volcanic activity at Mount Merapi Volcano in central Java, Indonesia, Jan. 7-8.
Event
Volcanic activity has been reported at Mount Merapi, located approximately 30 km (18 miles) north of Yogyakarta, Jan. 7-8. Officials maintain an exclusion zone of 3 km (1.9 miles) around the crater and an orange level 3 (standby) warning (second highest on a four-level scale).
Health
Further volcanic activity may impact air quality in parts of Central Java and the Special Region of Yogyakarta. 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. Authorities might 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 Mount Merapi 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.
