Ethiopian Volcanic Ash Clouds Delhi Sky: Safety Recommendations Issued

Post by : Saif Nasser

This week, Delhi and parts of northern India witnessed a unique phenomenon as volcanic ash from the Hayli Gubbi volcano in Ethiopia descended over the area. This volcano had been dormant for roughly 12,000 years before erupting and releasing a significant ash plume into the atmosphere last Sunday. The ash traveled thousands of kilometers, propelled by robust winds, surprising residents and prompting monitoring by local meteorological services.

Reports indicate that the volcanic plume ascended nearly 14 kilometers into the sky, with high-altitude winds, moving at speeds between 100 to 120 km/h, carrying the ash cloud across the Red Sea, Yemen, and Oman before extending over the Arabian Sea and eventually impacting Gujarat, Rajasthan, Delhi, Haryana, and Punjab. Meteorological officials in India confirmed that the ash remained high in the atmosphere and did not combine with surface-level pollution.

Experts from the India Meteorological Department (IMD) noted that many in Delhi may have observed a hazy appearance or milky sunlight throughout the day. IMD Director General M. Mohapatra highlighted that as the ash was airborne, it would not significantly affect local air quality. By late Monday, the majority of the plume had drifted eastward towards China, gradually dissipating.

Weather analysts noted that only a thin layer of dust and traces of sulfur dioxide were present around 40,000 feet in the atmosphere. These remnants are projected to dissipate soon, posing little discomfort to those on the ground. While no immediate threat was posed to India, experts acknowledged that volcanic ash can present health concerns under specific conditions.

The International Volcanic Health Hazard Network warns that volcanic ash can lead to respiratory issues, coughing, eye discomfort, and skin sensitivities, particularly when ash settles and is re-suspended. Reduced visibility poses additional dangers for outdoor movement and driving in affected regions.

To mitigate risks, experts recommend basic household safety measures. Residents should stay indoors as much as possible and refrain from unnecessary travel until conditions improve. Keeping windows and doors closed can help minimize ash intrusion. For those involved in outdoor clean-up, wearing dust masks is essential; if unavailable, a clean cloth mask can serve as a temporary substitute. Individuals with pre-existing respiratory conditions like asthma or chronic bronchitis should be especially cautious and limit exposure.

Wearing goggles can protect eyes from irritation, and filtered water that may have come into contact with a light dusting of ash is generally safe to drink. It is important to cover rainwater collection systems to prevent contamination. Vegetables harvested during this episode should be thoroughly washed before consumption. Parents are advised to keep children indoors and discourage strenuous activities until the air quality stabilizes.

Despite the unusual occurrence, experts reassure that the risk to the population in India is minimal. The primary consequence was a visual effect rather than hazardous pollution. Nevertheless, basic safety precautions are recommended until the last remnants of the high-altitude ash have cleared.
