Over the past month, the latest Sentinel-2 satellite acquisition detected elevated levels of water vapor and gas emissions from the volcano, mainly on 4 November as a relatively strong steam plume was emitted from the summit vent. By then, a passive venting of gas and steam emissions has been observed from the summit vent.

The volcano has been mostly calm since early January when the recent eruptive phase ended.

Whether it might be an early-phase indicator of an imminent eruption is unclear yet.
