JMA reported that minor eruptive activity continued to be recorded at Satsuma Iwo-jima, a subaerial part of Kikai's NW caldera rim, during 7-14 November. White gas-and-steam plumes rose 600 m above the crater rim. Surveillance cameras observed nightly incandescence.
JMA reported that eruptive activity continued to be recorded at Satsuma Iwo-jima, a subaerial part of Kikai's NW caldera rim, during 29 March through 4 April. White gas-and-steam plumes rose 1 km above the crater rim. Surveillance cameras observed nightly incandescence.
In response to an eruption at Satsuma Iwo-jima, a subaerial part of Kikai's NW caldera rim, on 2 November 2019 JMA had raised the Alert Level to 2 (on a 5-level scale). Since then, surveillance cameras sometimes recorded minor incandescence reflected in emitted plumes. On 8 March JMA revised the Alert Level guidelines, keeping the level at 2, but reducing the exclusion zone around the crater from 1 km to 500 m.

An eruption at Satsuma Iwo-jima, a subaerial part of Kikai's NW caldera rim, was detected at 1735 on 2 November, prompting JMA to raise the Alert Level to 2 (on a 5-level scale). 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.

JMA reported that the number of volcanic earthquakes at Satsuma Iwo-jima, a subaerial part of Kikai's NW caldera rim, was low during 20-26 April. White plumes rose as high as 700 m above the Iwo-dake lava dome; incandescence from the crater had not been visible since 12 April. During field surveys on 25 and 26 April observers noted a slight expansion of a thermally anomalous area compared to 24-25 March observations, and a decrease in sulfur dioxide flux from 600 tons/day on 24 March to 300 tons/day.

JMA reported that the number of volcanic earthquakes at Satsuma Iwo-jima, a subaerial part of Kikai's NW caldera rim, was low during 27 March-2 April after an increase recorded during 22-23 March. White plumes rose as high as 1.8 km above the Iwo-dake lava dome. Incandescence from the crater was visible at night during 27-28 March.

JMA reported that one small-amplitude, short-duration volcanic tremor was detected on 16 March at Satsuma Iwo-jima, a subaerial part of Kikai's NW caldera rim. The number of volcanic earthquakes increased on 19 March, prompting JMA to raise the Alert Level to 2 (on a 5-level scale), and then decreased the next day. The report noted increased thermal activity since February, with occasional visual observations of incandescence.

New activity seems to have started from Satsuma-Iwo-jima (Kikai) volcano. 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.

Plume activity at the Iodake summit crater has remained at relatively low levels since the middle of 2009, and white plumes rose to a heights of up to 400 m above the crater rim during the reporting period. Weak volcanic glows were recorded at night with a high-sensitivity camera on November 6th and 22nd to 24th.

According to JMA's report on 6 June, discolored plumes, associated with volcanic tremor, had intermittently issued from Kikai's summit since 11 May. In addition, the number of small volcanic earthquakes had increased since 29 May. Discolored plumes were observed from Mishima village on the Ryukyu Islands and ash fell on residential areas during 3-5 June.

Continuous volcanic tremor was recorded at Satsuma-Iwo-jima during 20 to at least 23 July. A seismometer about 700 m SW of Iwo-dake crater recorded 50-100 earthquakes daily, in comparison to 30-90 earthquakes recorded daily during December 2000 and March 2001. Small amounts of volcanic tremor were also occasionally recorded.
