The shaking ground of Campi Flegrei

I loved Naples. It is a lively Mediterranean city where there is always something going on. The people are amazing. I was told (a long time ago) by someone whose wife was from there that they were visiting the city, and his wife went somewhere and had told him in no uncertain terms to stay…

Ibu, an overlooked caldera

Indonesia is a country of volcanoes. An impressive amount of subduction-related volcanoes. The country features four different volcanic arcs, chains of volcanoes above subducting oceanic plates. The most important one is the Sunda Arc, home to way too many famous volcanoes like Toba, Krakatau, Galunggung, Merapi, Semeru, Bromo, Kawah Ijen, Batur, Agung, Rinjani, or Tambora.…

The land between the mountains

Double, double toil and trouble; Fire burn and caldron bubble Do you remember that famous Australia TV soap where everyone in the town helped each other with their mini-crises, such as ‘who took my surf board’ and where the life guard walked around the beach in their swimmers? (I may be getting confused here with…

Sun storm: the Carrington event

Lights of the North! As in eons ago, Not in vain from your home do ye over us glow! William Ross Wallace (1819–1881) A repost from 2018 with minor updates Jan 25, 880 AD, was a remarkable night. The Arabian historian Ibn Abi Zar wrote about it more than 400 years later, from the ancient…

The collapse of Anak Krakatau

The parent is famous. The shock waves of the eruption of Krakatoa in 1883 reverberated around the world – in the atmosphere, in the sea and in the news media. This was the first large eruption in the era of instant communication. The eruption itself was luckily on an island at some distance from human…

Iceland’s subglacial Skaftar-sized events

Due to the ongoing Reykjanes activity, I’ve grown interested in subglacial Icelandic lava flows. When lava is erupted under an ice cap, it tends to pile up rather than flow away. It makes a conical or ridge-like mound of pillow lavas known as a tindar. When lava reaches the surface of the glacier, it starts…

The New Lagoon and Iceland’s Thor adventure park

This of course was our annual April-1 breaking news. We hope you enjoyed it! This was a communal effort from the VC admins. The ideas came from a brainstorming session, the all-important images were sourced by Lughduniense and Gaz who had infiltrated ITO with a side order from AI and the text was filled in…

The story of Sydney

It is a spectacular city. The harbour bridge and the opera house are instantly recognizable, but scratch only the surface. Once those have been seen, it is time to explore the real city with its dense flocks of boats parked everywhere along the shore, the busy centre with the Queen Victoria shopping centre, the cliff…

Mountain of the Night: the lost Mars volcano

It should be easy to recognize a volcano. They stand high above the surrounding land, a singular cone which couldn’t really be anything else. Of course, they may not stay that way. Erosion may destroy the shape. A big explosion may replace the cone with a crater. Or there may never have been a cone,…
