A rare atmospheric event surprised residents on Friday as traces of volcanic ash were detected over Delhi–NCR. According to early assessments, the IMD increases monitoring following this unexpected phenomenon, which comes at a time when the region is already facing poor air quality. The presence of volcanic ash was confirmed through satellite observations and high-altitude atmospheric scans.
Meteorologists at the India Meteorological Department noted that the ash likely originated from a recent volcanic eruption in Southeast Asia. Strong upper-level winds transported the ash thousands of kilometres before it settled lightly over parts of northern India. With this development, the IMD increases monitoring of wind direction, particulate matter, and visibility levels.
Experts clarified that while volcanic ash at high altitudes poses limited direct health risks, its combination with local pollution may worsen symptoms for sensitive groups. Residents with respiratory issues, young children, and the elderly are advised to remain cautious.

Eyewitnesses in Delhi–NCR shared videos and photos showing an unusually hazy sky, prompting speculation on social media. Environmental agencies are collaborating with international weather organisations such as the World Meteorological Organization (outbound reference) and Smithsonian Global Volcanism Program (outbound reference) to identify the exact source of the ash plume.
An IMD official assured the situation is under control but emphasized ongoing assessment. The department is also preparing a detailed report that will outline the origin, density, and probable duration of the ash presence. As the IMD increases monitoring, updated advisories will be issued if conditions warrant changes.
