Foreshadowing #Aberfan. The failure of Tip 7 (1966/10/21) 60 years ago today resulted in the death of 116 children and 28 adults. In modern terms, this was corporate manslaughter. The National Coal Board knew that the tip was built over springs and Tip 4 (image GoogleEarth) had failed in 1944.

When I did my seismology PhD 40 years ago, I had to wait ~2 years for the seismograms to be collected, distributed on microfiche, travel to Edinburgh to copy them, before even starting analysis. Now you get Judith and Kyle producing 4 excellent data-rich articles in under a week after the ’quake.

OTD UK Earthquakes. 07:15UTC October 7, 1690 M5.2 Caernarfon, N. Wales. Little is known about this earthquake other than the felt area (London-Dublin) matches that of the 1984 M5.4 Llŷn Peninsula Earthquake, suggesting a similar location and magnitude.

OTD UK Earthquakes 03:22UTC October 06, 1863. M5.2 SW of Hereford. Damage in Hereford, Ross, Hay, Monmouth, Abergavenny. Felt Lake District - N. France. Probably associated with the Neath Disturbance. Effects in Kent described in a letter from Charles Dickens to his sister-in-law Georgy Hogarth.

A reminder that we already have an epoch for the duration of human interference with the Earth’s climate. It is called the Holocene.

Just as a reminder, in 2008, the year that Abu Dhabi bought Man City, Luton Town were deducted 30 points for financial irregularities probably involving less than 1% of this sum.

Standing on the Shoulders of Giants. This is my academic family tree (parent = PhD supervisor; grandparent = their supervisor, and so on.) I'm astonished to be able to get back to the early 1600s (I serendipitously discovered a short-cut). There are some illustrious scientists in this list.

I do dislike the in-built obsolesce of modern things. Perfectly good laptop destined for the scrap heap because progressively cut off from various software through lack of updates to os. Let’s give this linux thing another try.

Can’t vote today for the party I support (not standing in my ward) and can’t even afford to vote for my better half who is standing to be a councillor (not going to win). Have to vote for party I intensely dislike to attempt to keep out a party of racists, fuckwits and sociopaths that I despise.

I have been teaching introductory computer programming for geoscientists for almost forty years now. This year I have added in using AI. [Insert expletive here], what a game changer. Still have to cover fundamentals for understanding but I can spend far more time actually explaining things.

That’s a nice ring ditch you have there, it would be a shame if someone dug a powerline to a mobile phone mast through it. ⚒️🧪
