JMA recorded an eruption at Satsuma Iwo-jima (subaerial part of Kikai’s northwestern caldera rim) that was detected at 17:35 on 2 November.
A grayish-white plume rose 1 km above the Iodake crater rim. The report noted that the number of volcanic earthquakes has been low, with no variations before or after the event.
The next day during an overflight conducted by the Coast Guard and the Japan Meteorological Agency Mobile Survey Team (JMA-MOT) observers noted no changes to the geothermal field and no new deposits from the event the day before. Views of the crater were obscured by white plumes rising 300 m above the crater rim.
JMA raised the alert level to 2 (on a 5-level scale).

A steam / gas and possibly ash-containing plume has been observed on satellite images and a thermal anomaly was visible on recent MODIS satellite data. On yesterday morning's NASA Aqua satellite image, the plume from the volcano was about 70 km long to the SW. A thermal anomaly was visible already on images from 23 May. lire toutes
