New aerial images of the current volcano activity from 14 April by the Japan Coast Guard (JCG) were published today.
The behavior remains inherently unchanged, characterized by the near-frequent strong degassing, i.e. the continuing venting of gas and steam from the summit crater. The gas plume continued to rise about 1,900 m above the crater and drifted north during the investigation flight research.
This also confirms an image from the ESA Copernicus mission acquired by the Sentinel-2 satellite.
