Sentinel-5P detects severe volcanic eruption

At around 20:12 lo­cal time on 26 June 2018 (02:12 UTC on 27 June), the Sier­ra Ne­gra vol­cano erupt­ed on Is­abela Is­land in the Gala­pa­gos archipela­go. Sen­tinel-5P was above the area at ex­act­ly that time and was able to de­tect ex­treme­ly high con­cen­tra­tions of sul­phur diox­ide in its mea­sure­ments. With more than 500 DU (Dob­son unit), the de­tect­ed val­ues ex­ceed­ed the usu­al mea­sure­ment scale by a fac­tor of 100. The im­age con­tains mod­i­fied Coper­ni­cus Sen­tinel da­ta (2018), pro­cessed by DLR / BI­RA.

At around 20:12 local time on 26 June 2018 (02:12 UTC on 27 June), the Sierra Negra volcano erupted on Isabela Island in the Galapagos archipelago. Sentinel-5P was above the area at exactly that time and was able to detect extremely high concentrations of sulphur dioxide in its measurements. With more than 500 DU (Dobson unit), the detected values exceeded the usual measurement scale by a factor of 100. The image contains modified Copernicus Sentinel data (2018), processed by DLR / BIRA.
