JMA reported that the number of earthquakes with shallow hypocenters and epicenters near Ponmachineshiri Crater, a summit crater of Me-Akan (also known as Meakan-dake, which means Meakan Peak) of the Akan volcanic complex, increased at 1800 on 20 November. Another seismic increase occurred on 23 November, in number and amplitude of events, prompting JMA to raise the Alert Level to 2 (the second lowest level on a 5-level scale).
A new earthquake swarm is occurring at the Meakandake cone so JMA has raised the alert level to 2. A similar event occurred 3 years ago. The last eruption was in 2008.

Recent earthquakes under Meakan volcano (JMA)
A swarm of shallow volcanic earthquakes under the Ponmachineshiri crater of Mt Meakan volcano has been occurring since yesterday. This event triggered the Japanese Meteorological Agency (JMA) to raise the volcanic alert status to 2 (eruption alert, on a scale of 1-5) today.

JMA reported an eruption from Me-Akan (also known as Meakan-dake, which means Meakan Peak) of the Akan volcanic complex on 28 November. Ash plumes rose to an altitude of 2 km (6,600 ft) a.s.l. and drifted N, E, and SE.

On 17 November the alert level for Akan volcano was rised to level 3. There have been recorded tremors and a cloud that was the result of an ash eruption that covered the crater rim with black ash. Also ballsitic lithics were deposed around the crater.

On 17 November, JMA raised the Alert Level for Me-Akan (also known as Meakan-dake, which means Meakan Peak) of the Akan volcanic complex to "near-crater warning" (levels 2 and 3 on a 5-level scale) after the seismic network detected tremor that lasted 171 minutes. On 18 November, the summit was obscured by cloud cover but web camera views showed that the snow-covered S slopes had turned black. During an overflight later that day, JMA scientists noted that the ash covered an area up to 400 m away from Ponmachineshiri crater.

On 17 October, JMA lowered the Alert level for Me-Akan (also called Meakan-dake, which means Meakan Peak) of the Akan volcanic complex from near-crater warning to normal. Seismic tremor was no longer detected after 30 September, and seismicity had remained low after 3 October.

Seismic tremor from the Akan volcanic complex that lasted for four minutes on 29 September prompted JMA to raise the Alert Level from 1 to 2 (using a 1-5 scale). The number of earthquakes had increased since 26 September. A white plume rose less than 100 m above the Me-Akan volcano group. [Correction: The numbered Alert Level system was not applied to Akan.

Meakandake volcano in Hokkaido, Japan, erupted shortly on Tuesday afternoon, March 21, 2006. The volcano spewed a small amount of ash and caused a short lahar travelling through a ravine on the upper slopes of the snow-capped volcano.

A very small eruption occurred at Me-Akan (also called Meakan-dake, which means Meakan Peak) of the Akan volcanic complex on 21 March. Tremor began around 0628, the eruption apparently began around 0637, and an alert was issued by JMA at 0643. The eruption occurred from the volcano's NE flank.
