There has not been happening much in the volcano world these days.
Popocatépetl's activity in Mexico remains stable with about 2 weak explosions per hour. Most of these only produce steam plumes, only the stronger ones are accompanied by weak ash plumes. Crater glow is visible at night and a significant SO2 emission indicates that magma continues to rise in the volcano.
Explosive activity from Fuego volcano is increasing in favor of effusive. Since yesterday, there have been 13 weak to moderate explosions with ash rising up to 1000 m. The lava flow towards the Ash Canyon is still active and now 400 m long.
A mild ash explosion from the Santiaguito lava dome occurred this morning with a weak plume rising to 3100 m altitude. Activity otherwise remains mainly effusive. The thick block lava flows that descend from the summit are still weakly active and produce avalanches of rocks detaching from their fronts.
Heavy rainfalls around Tungurahua volcano in Ecuador triggered lahars one of which damaged the Baños-Penipe road.
The seismic swarm in the Tjörnes Fracture Zone north off Iceland continues and the Icelandic Civil protection issued warning about the possibility of a larger earthquake.

A new submarine eruption was observed from Fukutoku-Okanoba volcano in the Volcano Islands of Japan on Tuesday morning, October 16th. Japanese Coast Guard observed a column of white smoke rising from the sea about 3 miles from Minami-Iwoto island. According to a report "the volcano spewed ash and smoke about 100 meters into the air, and the surrounding sea area changed to a yellowish-green color while other parts became a cloudy gray". ...
