On the island of La Reunion, the eruption of the Piton de la Fournaise, which began Feb. 4, continues without significant changes in the tremor and geophysical parameters recorded by the OVPF. The rain stopped on the top middle of the day on February 11, and the south side of the volcano is visible again from the Bert Piton from 14:30.

The Turrialba, in Costa Rica, well deserves its name meaning "White Tower" in reference to the steam plume that usually overcomes.

Fumaroles of the western crater showed Feb. 11 early in the day an increasing of gas flow and water vapor, following the entry of large quantities of meteoric water in recent days.

In the Pacific, local news reported a new volcanic activity spot located about 72 km south-west of the island of Vava'u (or 20 km SW of Late island).

This review follows the observation, by a pilot during a flight from Ha'apai (the last eruption site confirmed in December 2014) to Vava'u on February 9 at 15:16, of a white vapor cloud amount more 2000 feet before drifting SW.

Subject, as no trace of pumice rafts or other floating volcanic debris, nor volcanic gas smell are reported.
