This week, residents of Delhi and northern India witnessed an unusual phenomenon as volcanic ash from Ethiopia blanketed their skies. The source of this ash was the Hayli Gubbi volcano, located in the Afar region of Ethiopia, which erupted after being dormant for almost 12,000 years, releasing a significant cloud of ash into the atmosphere on Sunday. The ash plume traveled thousands of kilometers, propelled by strong winds, catching the attention of meteorological agencies monitoring its trajectory.

The volcanic plume soared to an altitude of approximately 14 kilometers. Rapid high-altitude winds, measuring 100 to 120 km per hour, carried the ash cloud across the Red Sea, passing through Yemen and Oman, eventually reaching the Arabian Sea and sweeping over states such as Gujarat, Rajasthan, Delhi, Haryana, and Punjab. India's meteorological authorities clarified that the ash cloud remained in the upper atmosphere and did not mix with surface-level pollution.

Experts from the Indian Meteorological Department (IMD) indicated that residents in Delhi may have observed a slightly hazy skyline or a milky sunlight effect for several hours. IMD Director General M. Mohapatra reassured that the ash remained high above ground level, thus not posing any significant threat to air quality. By late Monday, the majority of the plume had shifted eastward towards China and began to dissipate.

Weather analysts confirmed that only a thin layer of dust and traces of sulfur dioxide were present at roughly 40,000 feet in the air. These particles are expected to clear out swiftly without causing significant discomfort for individuals on the ground. Although there’s no direct risk for India, experts warned that volcanic ash can present health risks in specific scenarios.

The International Volcanic Health Hazard Network notes that volcanic ash can lead to respiratory issues, coughing, eye irritation, and skin sensitivity, especially when ash settles on surfaces and is lifted back into the air by movement or wind. Ash-laden air can also compromise visibility, thus making outdoor activities hazardous.

In response, experts recommend adopting simple safety precautions. Staying indoors, when feasible, and avoiding unnecessary outings until conditions improve is advisable. Ensuring that windows and doors are closed can minimize ash intrusion into residences. For those who must venture outside for cleanup, wearing dust masks is advised; if unavailable, a clean cloth mask can be a temporary substitute. Individuals with pre-existing respiratory conditions should take extra care to limit exposure.

Wearing protective goggles can shield the eyes from irritation. Drinking water exposed to light ash is generally safe after filtration. However, rainwater collection systems should remain covered to avoid contamination. Harvested vegetables can be consumed after thorough washing. Children should also stay indoors and refrain from strenuous activities until normal conditions resume.

While this occurrence is both rare and striking, specialists assert that the threat to public health in India is minimal. Delhi and adjacent regions experienced merely a visual effect from the ash cloud, without hazardous pollution implications. Nonetheless, maintaining basic caution is recommended until any remaining high-altitude ash clears from the skies.
