Course - The Geology of Eruptions, Earthquakes and Tsunamis
When

Where
Wynstones School, Stroud Road, Whaddon, Gloucester (map)
Description
The Geology of Eruptions, Earthquakes and Tsunamis  
Three of the most devastating natural disaster-forming events are geological, all related to plate tectonics, and are very difficult, if not impossible, to accurately forecast.  What are the causes of these events and their various manifestations? Why are some more dangerous than others? How can we prevent or mitigate these effects? Examples of some of these phenomena will be used to illustrate these points Monday 7th for 10 weeks (not 18h Feb) until 18th March. Held at Wynstones School, Stroud Road, Whaddon, Gloucester from 7.30-9.30pm on Mondays . Cost £75

Geological Sites of the Bristol Region

Geological Sites of the Bristol Region





Since then I have received some correspondence giving mixed reviews of the book. Generally there is approval of the geological descriptions and explanations but universal condemnation of the maps. 

The location maps are virtually useless - try finding Pen Park Hole with this map - I tried and eventually resorted to Google Maps to find it.


The geological maps are worse. Have a look at this one -


Anyone care to give a geological explanation of the area? The legend for these "maps" is on the back flap of the dust jacket.

If there is a second edition of this book, and I hope there is, the maps need to be replaced if the book is to be regarded seriously. 

I have been told that there are mistakes and omissions in other parts of the text. My knowledge of Bristol geology is superficial so I would be grateful if persons with greater expertise would pass on to me their comments so that the next edition can be improved.

More on Anak Krakatau

More on Anak Krakatau

Following on from a previous post a correspondent sent me this link which has this fantastic photograph assembled from radar images taken from space.


One can see that the shape of the island is changing. The crater is no longer connected with the sea. Perhaps someone can tell me why the sea is coloured red.

For a closer look at the island there is some drone footage available.

Where
The Chantry, Thornbury. (map)
Description
Advances in Understanding Earth’s Structure and Operation. 
This 10 week course aims to introduce you to relatively new ideas, some accepted, some controversial, about the internal structure and tectonics of the Earth. Many ideas have changed radically since the inception of the Plate Tectonic hypothesis, and especially in the period from the 1990s, partly as a result of new technology, and the re-examination of parts of the theory that evidence did not support. Each week we will examine a different topic, such as subduction, mantle dynamics, mantle plumes.   Held at The Chantry, Thornbury.  First meeting 7.30 – 9.30, Thurs 10th January until March 21st (not Thurs 21st Feb). Cost £75

Naming extra-terrestrial things

Naming Extra-Terrestrial Things

I came across THIS ARTICLE and, while not very geological, is very interesting.
Did you know that large craters on Mars are named after deceased scientists and writers associated with Mars (there’s an Asimov and a Da Vinci), and craters less than 60km across are named after towns and villages on Earth (there’s a Bordeaux and a Cadiz)?

Or that the moons of Jupiter (except Io - see below) would be named using names from mythology - but in a way related to the Earths climatic zones!

  • Europa - mythical names from the European temperate zone
  • Ganymede - names from near-Eastern mythology
  • Callisto - names from far northern cultures
Part of Io, with fiery names

  • Io - However, because Io was revealed to be undergoing continual volcanic eruptions, the original naming theme was deemed inappropriate and was replaced by the names of fire, sun, thunder/lightning and volcano deities from across the world’s cultures. For example, the names Ah Peku, Camaxtli, Emakong, Maui, Shamshu, Tawhaki, and Tien Mu (which occur on the map above) come from fire, thunder or Sun myths of the Mayans, the Aztecs, New Britain, Hawaii, Arabia, the Maoris, and China, respectively.
There is a lot more of this, all of it interesting. 

I was drawn to this because a pal of mine, John Bunting, discovered an astrobleme in Western Australia - Yarrabubba, possibly the deepest eroded astrobleme on the planet - and as a reward has an asteroid named after him! 

He was assured that it was unlikely to strike earth any time soon! You can find it as number 19243 on THIS PAGE

Anak Krakatau - interesting detail

Anak Krakatau - Interesting Detail

In the last few days I have come across a couple of articles concerning the recent happenings at Anak Krakatau. The slightly more technical one can be seen HERE, and the one with the better pictures HERE.
