In its bulletin of 11 November 2015, the OVPF signals a new pressurization of the Piton de la Fournaise.

Seismicity is characterized by a large number of deep earthquakes (over 62) and summital earthquakes (130 earthquakes); since the end of the third phase of the effusive eruption in progress, the trend of inflation is clearly established.

The variation of the gas flow also reflects the deep pressurization. An aerial reconnaissance revealed that the Piton Kalla & Pele  tends to collapse on itself, and the persistence of high temperatures of the lava field, giving off numerous white fumaroles.

Seismic activity of the Tungurahua, in Ecuador, shows since the November 9 an increase compared with the previous week.

On November 10, from 15h, the amplitude of tremor emission has increased, to the point of saturate the seismic station near the crater for an hour. Three explosions were recorded between 9:39 p.m. and 23:59 LT , time that occurred the most important.

On 11 November from 2:52 local, the tremor saturated three times the seismic station, each time for about an hour.

The superficial and deep activity of Cotopaxi remains unchanged and characterized by gas and vapor emissions, with a low charge in ashes, and a maximum amount to 300 meters above the crater before drifting westwards.

In Indonesia, the Sinabung tirelessly pursues its business, with an eruption followed by pyroclastic flow on November 11 to 12:47 loc.

Rinjani is still active since October 25, and emits ash plumes estimated by the VAAC Darwin between 4.3 and 6.1 km above sea level derived in varying directions according to the dominance of the winds. On a Modis satellite view on this November 12, the plume is heading to the island of Bali, west of Lombok. A lava flow has been issued by the Barujari cone towards the crater lake.

The Jakarta Post reported the reopening of Lombok airport November 11, after being closed for a week.
