In Kilauea, the volcano continues its eruption in two places.
The lava flow 61 g, emitted on the flank of Pu'u O'o in the eastern rift zone, still enters the ocean at Kamokuna, where activity is concentrated on the eastern side of the delta. It currently measures more than 80,000 m², but faults suggest a collapse and a decrease of its surface at any time.
The numerous lava lobes create toxic plumes upon entering the waters of the Pacific.

A new branch is active east of Pu'u O'o and advances slowly, at the rate of about ten meters per day. Length of about 1,600 meters, it has many tongues and toes ​​where episodically the lava is emitted.

Since the beginning of December, the National Weather Service has issued a winter storm warning. This Weekend, the roads to the top of Mauna Kea and Mauna Loa are closed to the public above 3,000 meters.

Heavy rains caused a flooding of the Thurston lava tube in the Volcanoes National Park and disconnected the electrical system. The hiking trail in Nahuku is also closed.

Since 11 October, the Fuego has again increased his activity, with four to five light to moderate explosions per hour; Explosions are accompanied by falls of blocks and shock waves. The ashes are expelled to a height of 4,700 meters asl., dispersing towards the west, with falls on Panimache, Morelia, Santa Sofia and San Pedro Yapocapa. Explosions are accompanied by falls of blocks, shock waves and drops.

Monique De Saint-Cyr sent me a video made by Guy and Seifegebreil Shifferaw in Ethiopia, where the Erta Ale shows an "overflowing activity".
Regularly visited since 1967 by various expeditions, the pit crater south of the caldera sees the level of its lava lake varying in depth. At the end of January 2016, the jolts of the lava announced an overflow.
On the last journey "Voir naître la Terre" ("Seeing born the Earth") between November 8 and 20, 2016, the team of Adventure and Volcanoes was able to observe and film an exceptional overflow of lava in the caldera, on November 17th.
