Flights to Bali Resume: Navigating Volcanic Smog Health Risks
Flights to Bali have resumed after disruptions caused by eruptions from Mount Lewotobi in Indonesia’s East Nusa Tenggara province. Between November 4 and 13, 2024, volcanic activity led to the cancellation of over 160 flights, with a peak of 91 cancellations in one day. Ahmad Syaugi Shahab, the general manager of Bali’s Ngurah Rai airport, noted that flight operations are slowly returning to normal.
Mount Lewotobi is located about 800 kilometers (497 miles) from Bali’s tourist areas. Its eruptions created ash and smoke, leading to the formation of “vog,” which means volcanic smog. This phenomenon can affect health, especially for tourists visiting Bali.
Dr. Lokeshwaran explained that vog can irritate the eyes, throat, and lungs. Those with existing respiratory issues may feel stronger effects. Dr. Ravi Dosi from Kokilaben Dhirubhai Ambani Hospital highlighted how long-term exposure to vog could lead to chronic respiratory diseases such as Chronic Obstructive Pulmonary Disease (COPD). Immediate symptoms from acute exposure include coughing, breathing difficulties, chest discomfort, and eye irritation. Prolonged exposure can result in shortness of breath and ongoing coughing.
To mitigate the effects of vog, experts recommend the following precautions:
- Limit Outdoor Activities: Avoid outdoor activities on days with high vog levels.
- Use Air Purifiers: Employ air purifiers indoors to improve air quality.
- Wear Masks: Use N95 masks when outside to reduce exposure to harmful elements.
- Keep Windows and Doors Closed: Prevent vog from entering homes or enclosed spaces by keeping windows and doors shut.
These measures can help ensure a safer visit to Bali during periods of volcanic activity.
