Delhi Skies Covered by Ash from Ethiopian Volcano: Safety Measures Recommended

This week, residents of Delhi and northern India witnessed an unusual phenomenon as ash from the Hayli Gubbi volcano in Ethiopia's Afar region blanketed the skies. The previously dormant volcano erupted after roughly 12,000 years, sending an enormous ash plume high into the atmosphere on Sunday. Strong winds transported the ash thousands of kilometers, catching the attention of various nations and prompting local meteorologists to track its path.

Reports indicate that the volcanic plume ascended nearly 14 kilometers into the atmosphere, propelled by winds travelling at speeds of 100 to 120 km per hour, crossing over the Red Sea, Yemen, Oman, and subsequently spreading across the Arabian Sea before hovering over regions like Gujarat, Rajasthan, Delhi, Haryana, and Punjab. Nevertheless, Indian meteorological officials reassured that the ash remained in the upper atmosphere without mingling with surface-level pollutants.

Experts from the India Meteorological Department (IMD) noted that residents in Delhi might have observed a slight haze or milky sunlight for a few hours. IMD's Director General, M. Mohapatra, emphasized that since the ash lingered high above ground level, no significant adverse effects on the air quality were anticipated. By late Monday, most of the ash plume had drifted towards China, starting to dissipate.

Weather monitors confirmed that merely a thin layer of ash and a trace of sulfur dioxide were present at approximately 40,000 feet in the atmosphere. These remnants are projected to disperse soon, without causing substantial discomfort for those below. While this event does not present a direct threat to India, experts highlighted that volcanic ash can pose health risks under different circumstances.

The International Volcanic Health Hazard Network warns that volcanic ash may lead to issues such as breathing difficulties, coughing, eye irritation, and skin sensitivity, particularly when it settles on the ground and gets reintroduced into the air through movement or wind. Visibility can also decline, making outdoor activities or driving hazardous in affected areas.

In light of this, experts recommend straightforward precautions. It is advisable for individuals to stay indoors whenever possible and to minimize travel until the skies have cleared completely. Keeping windows and doors closed can help prevent ash from infiltrating homes. For those needing to venture outside for cleanup, the use of appropriate dust masks is advised. In the absence of a proper mask, a clean cloth mask can serve as a temporary measure. People with pre-existing respiratory issues like asthma should be particularly vigilant and limit their exposure.

Wearing goggles can help shield the eyes from irritation. Drinking water exposed to light ash is generally safe after filtration, but rainwater systems should be covered to avoid contamination. Vegetables gathered during this period should be thoroughly washed before consumption. Children are also encouraged to remain indoors and to avoid strenuous physical activities until normalcy returns.

While this event is both rare and visually striking, experts concur that the danger to residents in India remains exceedingly low. The passing ash cloud primarily resulted in a visual spectacle rather than hazardous pollution. Nonetheless, basic caution is recommended until the last remnants of the high-altitude ash have dissipated.
