New Delhi, Nov. 26 -- The ash cloud from the Hayli Gubbi volcanic eruption in Ethiopia will leave the Indian landmass by Tuesday evening, the India Meteorological Department (IMD) said on Tuesday. The ash plume travelled across Yemen, Oman and the Arabian Sea on Monday evening and entered Gujarat and Rajasthan. Around midnight, it came near Delhi and through Tuesday it moved across and east and northeast India. "We are expecting that the cloud will clear up from the Indian region by Wednesday. These are ash particles mainly which are moving at a height of 8km to 15km. So the main impact is on aviation and aircraft operations over Delhi, Kolkata and Mumbai. We have been issuing those warnings. There is no impact on the surface or the weather. There is no concern of exposure either because at that height, the wind speed is around 100kmph to 150kmph so the particles move away. There is hardly any time to settle down. But if a western disturbance were impacting us and there was rain, these particles would have settled," explained M Mohapatra, director general, IMD. The volcano erupted Sunday for the first time in nearly 10,000 years, prompting India to issue aviation alerts as ash clouds drifted across several northern states. Major carriers, including IndiGo and Akasa Air, adjusted their operations in response to the shifting plume as the impact on airspace became clearer. Authorities instructed airports to maintain heightened readiness as the ash cloud, travelling rapidly at high altitudes, entered Gujarat before moving over Rajasthan, Delhi, Haryana and Punjab. At Delhi airport, several international flights bound for destinations such as Hong Kong, Dubai, Jeddah, Helsinki, Kabul and Frankfurt were delayed, reflecting the wider operational disruption....
