Beautiful. Missing it. everything remains so crisp in the distance.

There might be some use in finding answers to a set question. But less in realising that there was a better question. That latter exercise is the hard part.

I should actually check with Alessio if the terraces on Noto Peninsula are relevant for WALIS (we will soon have radiometric ages for 5e). also working on digitizing all 7k+ 🗾MIS5e terraces from Koike and Machida (2001) Atlas. But only few have radiometric control.

The digitized marine terrace dataset can be downloaded as a shapefile on Zenodo (🔗 below). 4767 individual platforms distributed across 16 generations from the Atlas of Koike and Machida (2001). Maybe the most extensive erosive terrace record at a single site? 3/3

Realizing now that by traveling southwest from Berlin to Switzerland, I bought myself an extra 55 minutes of daylight on solstice day!

The EQ faults (& scarp) are drowned by the current high stand. Nearby Sado Island shares similar deformation record and is flanked by a similar nearshore scarp. It is the potential location of a large fault system initially suggested by Ota Yoko in 1992 (she was 🎯). 2/3

Shaking was strong, up to shindo 6+. I imagine that liquefaction is a bigger concern. We will know more in the morning.
NHK reports 6 injured in Aomori prefecture (falling objects and falls). 2/2

Fortunately, the M7.6 earthquake struck at low tide, reducing the impact of the tsunami (itself smaller than feared, max 70cm observed). 1/2

It makes a whole lot of sense yes, the coastal slope hosting the initial road is very landslide prone. (Actually the initial road has been wiped down). Google map has been updated, but the satellite images are still pre-EQ. Free flat land!

On Noto Peninsula where coseismic uplift was ~2m.
Sequence pre-earthquake, EQ +3 months, EQ +23 months. I thought we would be able to monitor this nice flat surface for weathering efficiency over the years…

Noto Earthquake and submarine landscape. After a loooong time looking for reviewers, we received good critical comments which led to notable revisions. Now back in review at GRL hoping that the 2nd round will be shorter than the 6 months of the first: doi.org/10.31223/X53...

He is still on the other place. But I’ll pass the message. I just saw him on Tuesday. It would be nice to read his posts again!
