Journalism is about impressions; science is about numbers. VC is standing in between these. We appreciate the immensity and power of volcanoes (and also appreciate that relatively speaking, these are manageable disasters. The human impact is awful for people concerned, but is not on the scale of major earthquakes or tsunamis. On balance, volcanoes create…
A Kilauea/Puna update has been appended at the end of the post Distance makes the heart grow fonder. Volcanoes are best loved from far away. The excitement of live lava is best viewed on a screen and not through the window. Of course, actual distance is good, but distance in time is also often deemed…
In Hawaiian folklore, Pele is vengeful and unpredictable. Her habitation is well known: Kilauea leaves little doubt about where Pele lives. But you never know where she may appear next. She shares this habit with Kilauea. It has a clear summit and all the action stems from there. But where the action will be next…
As I have perused the internet in the last few days I have noticed that the “gargantuan landslide causing a mega-tsunami” meme is in full swing again, now in relation to Kilauea. Therefore, I think it is time to write a more laidback article about what is happening in that regard with Kilauea. But before…
We humans may wish for many things, but gravity is a horse we can’t wish away. And this horse drives what is happening at Kilauea. So far, the new stage of the old Kilauea eruption that started about one week ago has given us a very small subsidence caldera, a large earthquake, drained two lava…
For a Kilauea update, see the bottom of the post Astronomy is a dangerous science. It is not just the fact that astronomers love to blow things up. Exploding stars are their bread and butter. For a bit of adventure, they collide black holes. And who else would start the history of everything with a…
Update May 8 No major changes. The lava pond in Kilauea is now reported as 220 meters down, and may still be dropping. The most recent images suggest it is still going down. Below 400 meters there would be a risk of ground water getting into the hole with phreatic consequences, but so far there…
Kyushu, the third largest island in Japan, considered the cradle of the japanese culture, is also a natural treasure and most of the wonders you can find there are volcanic spots. Some of the most active volcanoes in Asia lie here, and the island is also famous for the wonderful thermal areas. A trip around…
Volcanoes spring predictable surprises. Ever since Puʻu ʻŌʻō began to inflate it was clear that a new break-out was brewing. The 61-G flow had been in decline for many months: the spectacular ocean entry had ceased some time ago, and the flows had withdrawn to within a few miles of the origin. That is typical…
In Part I, the five main faults in the region around the Levant were discussed: the Red Sea spreading ridge and its associated triple point, the Dead Sea transform fault, the Zagros suture, the Anatolian strike-slip fault (actually two near parallel faults), and the Aegean subduction zone. Every type of fault that is known occurs…
Humanity has a long history of living on this Earth. During the days and years, our world continuously changed. We grew up in the shadows of the approaching ice ages. We left Africa when the changing sea opened up a road to Asia, and followed an ever-changing coast line to the far East. And throughout…
On Wednesday I was asked to look into the possibility that there had been an eruption on the West Coast of Sweden. It was one of those phone calls that are really confusing and making you wonder if it is you, or the rest of the Universe, that has gone utterly bonkers. Since it was…
Is this the most northerly elephant in the world? 200 meter tall and rising from the Atlantic Ocean, this Neptunic elephant lives at Heimaey Island, off the south coast of Iceland. A combination of basalt and wave erosion has left a convincing elephant head, complete with deeply wrinkled trunk. There are other elephant rocks in…
What happens when an unstoppable force meats two unmovable objects? Well, in the world of geology there should be volcanism. A few weeks ago, I was asked by a person who did not believe in science this specific question. “If plate tectonics are real, why then are there no volcanoes in Norway?” It is a…
Hekla is the most mysterious of Iceland’s many volcanoes. Its brooding summit overlooks the broken plains 800 meter below as if it were an English Lord (or perhaps Lady) of the Manor. The fiefdom looks bare and uninviting, but that is not purely Hekla’s fault: once this was dense forest, but it was cut down…
