Volcanic Ash Clouds Disrupt Air Travel Across Asia

Volcanic ash plumes, composed of ash, sulfur dioxide, and rock particles, have risen to altitudes of 10-15 kilometers, causing significant disruption to air travel. The ash cloud has been observed drifting across the Red Sea towards the Middle East and Central Asia, prompting airlines to cancel numerous flights and reroute others through airspace previously unavailable to them. IndiGo, for instance, had to cancel six flights.

The situation is expected to intensify, with aviation authorities and the Directorate General of Civil Aviation closely monitoring the ash’s trajectory. If the plumes reach cities like Delhi and Jaipur, Indian aviation could face severe impacts. The ash is moving at speeds of 100-120 km/h, posing a direct threat to flight operations at altitudes between 15,000 and 45,000 feet.
