The Hayli Gubbi volcano in northeast Ethiopia, believed to have been dormant for as much as 12 000 years, erupted on 23 November 2025, sending a large plume of ash and sulphur dioxide excessive into the ambiance.
The realm surrounding the volcano is basically uninhabited and tough to entry, making satellite tv for pc knowledge and imagery important for monitoring occasions in distant areas equivalent to this.
The Copernicus Sentinel-5 Precursor satellite tv for pc has captured two pictures of this shocking eruption, one on 23 November and one the next day. The primary exhibits the plume of sulphur dioxide billowing from the volcano on the time of the eruption or shortly after. Right here, the plume is beginning to drift eastward over elements of the southwestern Arabian Peninsula.
The second picture, captured on 24 November, exhibits how the plume dispersed north-eastward alongside the coasts of Yemen, Oman and the Arabian Sea.
Sentinel-5 Precursor is the primary Copernicus mission devoted to atmospheric monitoring. The satellite tv for pc carries an instrument known as Tropomi to map a variety of hint gases and aerosols – that have an effect on air high quality and local weather.
The not too long ago launched Copernicus Sentinel-5A instrument, abord the primary MetOp Second Era satellite tv for pc, builds on this capability by offering day by day international measurements of atmospheric gases and aerosols. Its observations embrace key air pollution, important local weather variables, and stratospheric ozone that protects us from ultraviolet radiation.
