Copernicus Sentinels catch emissions of volcanic eruption
12 July 2019
Dormant since 1924, the Raikoke Volcano in the Kuril Island chain, near the Kamchatka Peninsula in Russia, recently awoke. Data from the Copernicus Sentinel-5P and Sentinel-3 satellites are giving vital information on its aftermath.
On 21 June at about 18:00 UTC, the circular 2.5 km x 2.0 km island discharged a vast plume of volcanic gases and ash, between 7 and 15 km into the sky. The thick plume was carried to the east by a cyclone in the North Pacific, which the Copernicus Sentinel-3 and Sentinel-5P satellites recorded.
