June 22 Eruption at Raikoke, Kuril Islands

 

NASA ISS photo of Raikoke in eruption taken June 22. Active plume with water vapor collar at the base. Water vapor collar at the base may be due to ambient air sucked upwards with the plume. Alternately, it may be due to interaction of pyroclastic flows with surrounding sea water. Image courtesy NASA Earth Observatory.

TINAKULA 🇸🇧 – New Photos & Update

In our post about Tinakula’s October 2017 eruption I wrote: “This island is so remote that exiting news of an eruption may come through within a few days, but we will probably never learn when, how, or if at all the eruption has ended.”

Well, officially the eruption seems to have ended on 26 October 2017, as listed by the GVP. However, National Situation Reports by the NDMO appeared up into the first week of November; a volcanic assessment on Tinakula on Nov. 5 showed numerous eruptions

Flank Collapse at Anak Krakatau, Dec. 22, 2018

Anak Krakatau a week following flank collapse eruption Dec. 22. The vent region has not yet been rebuilt above water level. Highest remaining part of the island is the hyaloclastic ring that used to host the most recent cone. Note also the island has been resurfaced and grown a bit.

Ima Itikarai, RVO, on 29 January 2005:
“… it has been a very eventful week … Tavurvur resumed eruption on Monday evening and Manam produced another paroxysmal eruption on Thursday night … . Our observation post at Warisi village was wiped out completely by what is described as pyroclastic flow … . All our equipment was destroyed by the event. There were about 14 people at Warisi at the time of the eruption and all got injured while trying to escape …” (From “Fire Mountains of the Island”)

AN IMMENSE BOILING POT: VOLCÁN RINCÓN de la VIEJA (CR)

Rincón de la Vieja is one of those volcanoes that don’t make headlines with fiery lava streams and end-of-world scenarios. Presently, the biggest news from it are about yet another phreatic explosion, and the most exciting photos show a pale steam plume fading away, at best with a bit of ash mixed in. Moreover, the videos of ensuing lahars we have recently seen show

TINAKULA

Tinakula volcano of the Solomon Islands in the South Pacific ocean started an eruption on 21 October 2017. Whether or not the volcano is still erupting is everybody’s guess as no more official reports were issued after the 6th of November and satellite imagery is inconclusive. Update 17/11: GVP has just listed the eruption as lasting from 21 – 26 Oct. 2017, classified as a VEI=3. However, the reports have stated still ongoing explosions on Nov. 6, so, I expect there might be amendments later.
