Ethiopian Volcano Eruption: Impact on Air Travel and Environment

The Hayli Gubbi volcano in Ethiopia, which had been dormant for several millennia, unexpectedly erupted on Sunday, propelling a substantial column of ash thousands of feet into the atmosphere. This volcanic plume has traversed an extensive geographical area, crossing the Red Sea and sweeping through Oman and Yemen before reaching the Indian capital, Delhi.

The eruption has precipitated significant disruptions to aviation operations across multiple regions. In India, numerous international and domestic flights have been cancelled, delayed, or rerouted due to the presence of volcanic ash in the upper atmosphere. The country's aviation regulatory body has issued stringent advisories to airlines, urging them to circumvent affected areas meticulously.

Volcanic ash poses a considerable threat to aircraft safety. Composed of minute, abrasive particles, it has the potential to inflict damage on aircraft engines, contaminate airfields, and severely impair visibility. These factors collectively render flying conditions hazardous in ash-affected zones.

Meteorological experts have indicated that the ash plume is situated at altitudes ranging from 8.5 to 15 kilometers above sea level. While this elevation suggests minimal impact on ground-level air quality, it presents substantial challenges for high-altitude flight operations and may temporarily affect satellite functionality. The ash cloud is projected to continue its eastward trajectory towards China.

This incident has evoked memories of the 2010 eruption of Iceland's Eyjafjallajökull volcano, which resulted in unprecedented disruptions to global air travel, underscoring the far-reaching consequences that volcanic activity can have on modern aviation infrastructure.
