It seems very likely that a new eruption has been taking place at the remote volcano: since mid June, and in particular during the second half of July, a moderate to strong thermal anomaly has been present at the volcano's summit.
The nature of this activity is unknown: it could be from strombolian activity, a small lava lake, and / or new lava flows (although a quick browse through satellite images did not show dark spots that would be expected in case of lava flows).
