yesterday in the Maurienne Valley, french 🇫🇷, causing the cut of roads to Italy 🇮🇹.

The relation to the melting, as suggested in the paper, is questionable because of low elevation of the event…
But any impact from the heavy rains of past days?

Ecroulement rocheux hier en vallée de entraînant la coupure des voies de communication vers l’Italie.

La relation avec la fonte du , comme suggéré dans l’article ci-dessous, me paraît assez douteuse compte tenu de l’altitude de l’événement.
En revanche, une relation avec les précipitations des derniers jours?

At What Scales Does A River Meander? Scale-Specific Sinuosity (S3) Metric For Quantifying Stream Meander Size Distribution
--
doi.org/10.1016/j.geomorph.202 <-- shared paper
--
“HIGHLIGHTS:
• Scale-specific sinuosity (S3) summarizes bend sizes of linear features and associated contributions to sinuosity across a range of scales.
• The S3 plot is analogous to a frequency histogram of bend sizes, like a fingerprint or a spectral signature
• The S3 is an easily computed metric to assess influential scales in bend patterns of linear stream features
• The paper formalizes a relation between sinuosity and fractal dimension..."

Dynamique des ruissellements basaltiques tertiaires et erosion des massifs secondaires. Vous avez 4 heures.

C'Ă©tait sur une plage, au nord de Montrose, c'Ă©tait joli, aussi.

Dynamics of tertiary basaltic runoff and erosion of secondary massifs. You have 4 hours.

It was on a beach, north of Montrose, it was pretty, too...

Earlier this summer I came across this stream with deposits of leaves more than 50 cm deep adjacent to the channel. Has anyone seen this before? Is this ?

The ground is still moving in Rolling Hills Estates in California…

"By Monday morning, multiple homes had slid down the hillside that borders the southeast side of the street, dipping below what was left of their driveways, some almost completely hidden from the road they previously lined.

"Garage doors were almost flattened, roofs had caved in, massive crevices exposed beams and pipes. Many of the homes were already gone."

À la rencontre de l'If de Fortingal, un des arbres les plus vieux du monde. Probablement plus de 5000 ans. On ne reste pas de marbre devant une vie aussi longue, surtout quand on a étudié l'Holocène...

Meet the Fortingal Yew, one of the oldest trees in the world. Probably more than 5000 years old. We don't remain unmoved by such a long life, especially when we have studied the Holocene...

So this is all good for and , but what about ?

Well, that impact created fissures. Fun little new interfaces that micobes could colonize.

And places where different rock material got mixed (like sandstone getting dragged through basalt).

The impact itself might have been a bummer moment (2-4 GPa!!!), but afterwards with those fluids mixing nutrients (like metal ions for rock-eating bacteria) and different materials around make grat places to look for life!
