This #map of the Mont Blanc region dates back to June 1794. The rivers and lakes are almost exact and accurate. On the other hand the mountains are quite fanciful. They are represented like linear ridges placed there to separate the valleys. And even these simplified orographic plots are quite wrong.This reveals that mountains were much less explored and mapped at that time.

@haq Thanks so much for these comments.
When you say "he wouldn't have mentioned her name without her permission", was that common usage at the time? I mean, not simply referring to the publication as we do now.

Maria Graham's excerpt is from: Maria Graham, 1824, An Account of Some Effects of the Late Earthquakes in Chili, Transactions of the Geological Society, 2nd series, 24, 413-415.

Darwin's excerpt is from the famous voyage of the Beagle book: Darwin, C. R. 1845. Journal of researches into the natural history and geology of the countries visited during the voyage of H.M.S. Beagle round the world, under the Command of Capt. Fitz Roy, R.N. 2d edition. London: John Murray.

I cannot find any mention of Maria Graham account on the 1822 earthquake in Darwin's book.

I am totally astounded by what I read when I compare these two texts: Maria Graham's description of the coastal #uplift due to the 1822 #Valparaiso #earthquake, versus Charles Darwin's text on very similar phenomena related to the 1835 #Concepción earthquake.

Read carefully, paying attention to the expressions used. It's like if #Darwin borrowed Maria Graham's words, but also her interpretation about the accumulation of earthquakes raising the coast on the long term. 🤔
Any comment ?

Both 1822 and 1835 earthquakes happened in Central #Chile on the #subduction #megathrust between Nazca and South America #tectonic_plates. Darwin's description, based on Fitz Roy (Beagle's captain) observations, is considered as seminal.

Thanks @haq for pointing me to the work by Maria Graham.

@YoFukushima Fine study! But possibly misleading media's title.

Lay people may understand it as: "high probability of (twin) earthquakes [in the near future] in Nankai Trough."

While your message is rather that: IF one M8+ #earthquake happens in the Nankai Trough, THEN the probability of a second big one there is quite high (but with large uncertainty). Japan Times article rightly explain this, but their title not really.

Thanks you all for these kind words!

Comments, and suggestions for future posts, welcome 😀

In my new #tectoldies post I follow up on the 1891 #Japan #earthquake and the seminal article by Bunjiro Kotô published in 1893:

https://tectoldies.mystrikingly.com/blog/the-great-1891-earthquake-in-central-japan-2

In this article, probably for the first time in the world, B. Kotô makes detailed descriptions of the earthquake surface rupture and offsets, and explicitly linked #earthquakes to #tectonic faulting.

Kotô gave a beautiful 3D sketch 👇🏼 and an amazing narrative about mole-tracks (a now commonly used term for some specific surface ruptures): “Amongst the extraordinary things done by the earthquake, one that always drew attention was the earth-rent. It strikes across hills and paddy-fields alike, cutting up the soft earth into enormous clods and raising them above the surface. It resembles the pathway of a gigantic mole more than anything else.”

I wrote in my previous toot that I'm not a #dendroclimatologist. If more skilled researchers can interpret, or use the section of our just cut down #spruce tree that was dying because of dark beetle, here are some good photos. Don't hesitate to comment.

It's from our garden very close to #Fontainebleau #forest, just south of Paris in France. (ruler in cm)

#dendroclimatology #climatechange

As said yesterday, we had to cut down our 40 years old dying #spruce tree. It was severely attacked by bark beetle (you can see the holes on the edge of whole trunk section, and the larvae on other photos), likely after being stressed and weakened by #heatwave and #drought in the past years. A probable effect of #climatechange, #climatecrisis.

It's from our garden very close to #Fontainebleau #forest, 60km south of Paris, France.

I'm not a #dendroclimatologist so I cannot interpret in detail the trunk section. But I will post hr photos in next toot for those more skilled.

Task of the day: splitting wood 👇🏼

We had to cut down our 40 years old dying spruce tree 🌲. Will say more about it in forthcoming toots.

I just revived my #Tectoldies blog, which was a little sleepy for a while, with a new post about the first ever described #earthquake surface rupture (that of the 1891 Nobi Mw~7.5 earthquake in central Japan). 1/n

The 1891 fault rupture was indeed perfectly described and interpreted by Bunjiro Kotô in a 1893 article. It is admirably imaged by a B&W photograph in Kotô's article, and by this delicate anonymous watercolour painting 👇🏼, perhaps the first artist view of an active tectonic fault.

My Tectoldies blog is about “the beauty of tectonics – the art of geological sections & other tectonic sketches.” Feel free to explore and comment previous posts. I'll toot about some of them soon.

WHAT ? French president, Emmanuel Macron, literally writes:

Who could have predicted the climate crisis…?

Who 🤔 ?
➡️ Thousands of scientists
➡️ 6 IPCC reports
➡️ 27 COP
➡️ even EXXON researchers tens of years ago
etc…
