: (29 Oct
) Our recent group who visited the volcano reports small to moderate explosion from the central vent at intervals of 5-20 minutes.Cotopaxi (Ecuador)
: No significant changes in the volcano's activity have occurred. According to monitoring scientists from IGEPN, it seems that magma is slowly rising inside an open-conduit system.
During the last week, visual activity mainly consisted in steam and gas emissions reaching 1-2 km height, as well as small explosions in the crater that could only be detected instrumentally. Ash emissions have been minimal. Overall seismic activity has slightly decreased, with averages of 30-50 volcano-tectonic earthquakes (VT) per day. SO2 emissions remained high, fluctuating at values of 2000-5600 tons / day.

: While the volcano continues to degas strongly and has intermittent, mostly small ash emissions, a stronger explosion occurred again early on 23 Oct around 6 am local time. ...
Sunday, Oct 25, 2015
: A small explosive eruption with ash emissions was reported from the volcano this morning. It seems to have occurred from the Baru Jari cone inside the caldera lake (and the site of all recent eruptions of the volcano) at around 10:45 local time. ...

: (23 Oct
) A moderately sized pyroclastic flow as result of small collapse of part of the active lava dome occurred this afternoon (Kamchatka time), sending an ash plume to approx. 15,000 ft (4.5 km) altitude. ...

Nishino-shima (Volcano Islands, Japan)
: (21 Oct
) The eruption that had started in Nov 2013 still continues with no significant changes. During the most recent survey on 18 Oct by the Japanese Coast guard, strombolian activity was observed at the central vent, but lava flows no longer reached the coast of the young island, which is being affected and modified by wave erosion. ...

Mayon volcano photos
: Mayon on Luzon Island, towering above Legazpi city is famous for being one of the most perfectly symmetrical stratovolcanoes in the world. It is also one of the most active and most dangerous volcanoes (not only) in the Philippines.
