The Rings of Power and the creation of Mordor

I'm working my way through the series now that all episodes have been screened.

At the end of Episode 6 of 'The Rings of Power' there is a volcanic eruption.

This is a pthreatomagmatic eruption it appears, when large amounts of steam are generated when water comes into contact with magma.

This is an eruption which has been 'confirmed by volcano specalists' as being possible.

Galadriel and others are caught up in a pyroclastic flow, but survive - although that would not be possible.

Violent volcanic eruptions occur in large part because water is involved. The water is dissolved in the magma. The magma rises to the surfaces, the water makes bubbles that can turn to steam and the steam and water expand so rapidly that they basically blow the magma apart. That stuff piles up near a central vent and that’s what makes big volcanoes. If that water is in a confined area, like a bottleneck, there’s going to be a steam eruption — we call it a phreatomagmatic eruption. We see that happening in Hawaii all the time where lava flows into the ocean, and some of the lava can get blown around if the water gets trapped under it.”

This links with the creation of Mordor, and provides the shadow that the Orcs need, while removing the former beauty. There is a strong link here with the environmental themes in Tolkien's writing.

On the trail of the 'Detectorists'

As I was in Suffolk last week, I headed for Framlingham as I knew that there were various locations from the series 'Detectorists' and also a wonderful pub just a few miles away where we could go for lunch. Parked up in the Market Square, and from there it was a short walk to several locations. Here are plenty more on a map. Managed to track down four locations: the outside of the 'Two Brewers' pub (the interior was filmed elsewhere), Lance's upstairs flat, the shop where Lance's former partner sells Spiritual goods and scented candles, and the village hall where the DMDC met. Here's me outside said hut. Don't forget the uniformbooks book of course. Still available and an excellent read.

Jonathan Meades on Sustainability

Have blogged about Jonathan Meades before, and his particular presentation style which I like... Lunchtime today was spent in the company of the first in the series "Off-Kilter", made for BBC Scotland and was about Aberdeen . I liked the look of the area known as Fitty. Towards the end, he moved on to Donald Trump and his controversial plans for a golf course in the sand dunes close to Aberdeen. He called the planned development "New Trumpton on Sea" and talked about gated communities and their absentee residents. He riffed on the idea of ' sustainability ' and how every architect and development trumpeted its sustainable credentials. New words like : "Sustain-abulous" and "Sustain-astic" ! Called it "architectural correctness"... "It's a slogan of conformist unoriginality..." "The very act of making a building is energy hungry and vastly wasteful even if the building is an eco-igloo of Fairtrade otter dropp...

Street Art trail of Reykjavik

I'm heading for Iceland again in April, and have made a start on updating my notes for the group I will be taking. I do this for each group that I take, and also have a chat with the group leader to ensure that I pitch my explanations and talking on the coach (and in situ) correctly. There is plenty of street art in the city of Reykjavik (and of course in other parts of the country). I've added a few images that I've taken below. These are mostly off the street called Laugavegur. I know roughly where they are, but am going to try to map them and then piece them together to make a nice map. Images: Alan Parkinson Guide to Iceland has produced an illustrated list of their own favourites. This is not easy to navigate as each icon needs to be clicked on. I've produced a Google Form where you can enter the location of your favourite street art. If you know the What3Words address that would be an additional extra. The form link is here: It would be good to eventually h...
