“Geldingadalir Volcano in Iceland went though its almost 3 month existence through different phases of eruptions. First it was Explosive Eruption, then Fire Lava Geyser, Strombolian Eruption and now is in Hawaiian Effusive Eruption. In couple of last days eruptions are coming back in almost exactly 10 minutes intervals. These Three Eruption in this video were taken last night (June 8/9 2021). This program compliment yesterday footage taken during the day time and it’s up to you decide whether Volcano Eruption are better during the day or night.” – Jiri VonDrak

Sinabung has been erupting sporadically since 2010, when it killed two people, but farmers refuse to leave its deadly slopes because the land is so fertile.
That’s Sinabung, as in Mount Sinabung, Sumatra, Indonesia.

Matua Island, MFN* (Strutts News Services) – It happens:
“This detailed astronaut photograph is exciting to volcanologists because it captures several phenomena that occur during the earliest stages of an explosive volcanic eruption. The main column is one of a series of plumes that rose above Matua Island on June 12. The plume appears to be a combination of brown ash and white steam. The vigorously rising plume gives the steam a bubble-like appearance. The eruption cleared a circle in the cloud deck. The clearing may result from the shockwave from the eruption or from sinking air around the eruption plume: as the plume rises, air flows down around the sides like water flowing off the back of a surfacing dolphin. As air sinks, it tends to warm and expand; clouds in the air evaporate.”
The phrase, “detailed astronaut photograph,” disturbs some folks, as there is no astronaut, detailed or otherwise, in the image. Assuming there was such an entity, and that the image was indeed captured via a detailed astronaut, there are many unanswered questions that need to be answered or otherwise ignored. For example:
Which way was this “detailed astronaut” being pointed when the picture was taken? What size mm lens, what film speed (400 ASA or greater?) and what was his/her f-stop setting? Where was this detailed astronaut’s aperature located? Who aimed the astronaut? How on earth did he/she control the shutter speed?
Regardless, it’s a cool photo.
