The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Kilauea is the youngest and most active Hawaiian shield volcano, located on the southern part of the Island of Hawai'i, known as Big Island. Hawai'i is the southernmost and largest of the island chain, which owes its existence to the very active Hawaiian hot spot.
Kilauea volcano is near-constantly erupting from vents either on its summit (caldera) or on the rift zones. At present, Kilauea volcano is still having one of the most long-lived eruptions known on earth, which started in 1983 on the eastern rift zone and has mainly been concentrated at the Pu'u 'O'o vent.
Lava flows on the pali from Kilauea's episode 61g flow yesterday night (14 Nov 2017)
After 16 months of continuous activity, the Kamokuna lava entry into the ocean stopped a few days ago. It had decreased gradually over the past weeks and intermittently resumed during the past days, probably fed by remaining batches of lava in the lower tube system that fed it. ...more
It seems that the main lava tube further upslope feeding the 61g lava flow became obstructed, forcing the lava to break out at the surface. When we visited the area yesterday evening, we witnessed a large breakout from a new vent on the upper pali, which fed multiple rapidly advancing channeled aa lava flows descending the pali into the upper coastal plain. Two wide-spread pahoehoe lava flow branches with scattered breakouts are active in the upper half of the coastal plain above the (now inactive) Kamokuna ocean entry. It seems likely that lava will find its way to the sea again in a near future. [less]

Accompanied by ongoing inflationary tilt, the Halema'uma'u lava lake at Kilauea's summit continues to rise and was about 14.5 m (48 ft) below the pit crater's rim this morning. It is currently very well visible from the Jagger Museum's lookout. ...more
At the Kamokuna ocean entry, the fire hose - which was going on very strongly last week (see video below) - had stopped over night and when observed this morning by boat, only a much weaker lava fall was visible. In addition, a new lava bench has finally started to form at the entry point, suggesting that after 2 1/2 months of fire hose activity, the submarine landslide scar seems to have been "healed" (filled-in with lava) sufficiently to support a new bench. Whether this will be stable for at least some time or soon collapse again, and whether the lava output from the exposed tube will again increase sufficiently to produce a free, arched fire hose is impossible to predict. The surface lava flow at the eastern margin of the episode 61g lava flow remains well active between near the base of the pali and about half way to the coast, with multiple active pahoehoe breakouts when we visited the area last evening.

Kilauea's spectacular fire hose - the exposed open lava tube feeding a jet of lava plunging into the sea
No significant changes have occurred over the past weeks. Kīlauea volcano continues to erupt from at its summit (active lava lake in Halema'uma'u) and from the Puʻu ʻŌʻō vent on the East Rift Zone. From the latter, the s-called 61g lava flow travels southeast, mostly through a lava tube, which enters the ocean in form of a spectacular fire hose at Kamokuna. ...more
Small surface breakouts from this lava flow are also present above and on the pali as well as half-way between the coast and the base of the pali when visited by our ongoing Kilauea Volcano Special tour. A short period of deflation (which has caused a temporary drop of the lava lake to be out of view from Jagger lookout) ended yesterday and the lava lake level rose again to about 23.5 m (77 ft) below the Overlook crater rim when measured this morning.

The dual eruption of Kilauea volcano, both at the summit (maintaining an active lava lake in Halema'uma'u crater) and from the east rift zone (lava flows from Pu'u 'O'o) continues with no significant changes. ...more
The lava lake at the summit continues to rise and fall along with inflation and deflation cycles. At the moment, it is relatively high and can be seen from the Jagger museum's lookout. The so-called 61g lava flow from Pu'u 'O'o remains active and continues to enter the ocean at Kamokuna. Since the large collapse on 31 Dec last year, the cliffs remain highly unstable in that area. Another collapse occurred on 11 Feb. and affected a small piece of the sea cliff west of the active ocean entry. [less]
Blue flames of burning sulfur: Ijen volcano in East Java has one of the most impressive sulfur deposits on earth. They are so hot that the sulfur often ignites - a mysterious display at night caught on camera.
Try our new app!: Volcanoes & Earthquakes - our new free App for Android shows the latest earthquakes and active volcanoes on a map and as list, as well as volcano news from all the world. You can filter the data shown in various ways, e.g. by magnitude or age of earthquakes, the distance from your location, the status of volcanoes and so on.
