This #Sentinel3 #satellite 🛰️ image shows the impact of the 15 Jan 2022 Hunga #Tonga #volcano #eruption 🌋 on ocean 🌊 color 🌈 . The image was acquired ~ 24 hours after eruption. Anomaly is here shown in terms of "suspended matter", derived from measurements of the OCLI instrument . It is caused by ash fallouts from the volcanic eruption. In the following days, the anomaly gets dispersed by winds and oceanic currents.
Data: (C) #ESA-#Copernicus / #EUMETSAT
The radar image shows the volcanic edifice of #Shiveluch (#Kamtchatka). The volcano is seen from an oblique view. The top of the #volcano is missing, as it collapsed in an eruption in 1964. In place of the missing volcano summit, one can observe a large horseshoe-shaped depression. The bottom of the depression is filled with a new lava lobe, made of semi-solid rock, that appears to have formed since the 10 April 2023 eruption.
This spectacular image shows the #Shiveluch volcano (Russia) after a recent eruption on Apr 10. #SAR provides a unique opportunity to image the status of the volcano. Experts have looked at our data & noticed a possible new lava dome forming. #volcano
