The Oman Environment Authority has issued a public advisory following the unprecedented eruption of Ethiopia’s Hayli Gubbi volcano, which had remained dormant for 10,000 years. The eruption, which began on November 23, 2025, at approximately 8:30 AM UTC, sent towering ash plumes soaring up to 15 kilometers into the atmosphere. These ash clouds drifted across the Red Sea, impacting regions in Yemen and Oman. Despite the significant scale of the eruption, Oman’s monitoring stations have not yet detected any rise in pollutant levels or deterioration in air quality. The authority has assured the public that continuous monitoring is underway through 68 stations across the country, including key locations in Dhofar and Al Wusta. Real-time air quality updates are accessible via the ‘Naqi’ platform. Aviation authorities have also been alerted due to the extensive ash cloud, which reached altitudes of nearly 20,000 feet. Scientists have described the event as one of the most remarkable volcanic awakenings in the region’s recorded history. The Oman Environment Authority has pledged to keep the public informed of any developments.
