Our new paper out now in QSA models the Storegga tusnami wave using more realistic palaeobathymetry based on the most recent glacio-isostatic modelling outputs for the North Sea, and shows that significant wave propagation south of Dogger Bank is extremely unlikely.

"Propagation of the Storegga tsunami in the southeastern North Sea" is published in Quaternary Research Advances today. Open access paper (doi.org/10.1016/j.qs...) examining the degree to which the tsunami from the 8150 BP Storegga slide would have been able to reach the coasts of Denmark+Germany.

I finally made it back to Uki City in Kumamoto, nearly 2 months after the severe earthquake. Since it has also been extremely dry, there are still visible cracks in the ground at the property I am maintaining. #earthquake

A picture showing a visible crack in the ground next to a building. This crack was caused by the Uki Earthquake, which was a magnitude 6.8, and an epicenter about 5 km from this location.

The touchscreen on my Samsung phone was not randomly not responding over the past few days. Locking the screen would fix the problem for a bit, but the problem would soon return. I figured out what caused it. I cleared the cache on Google Chrome (which was at >2 GB), and this no longer happened.

Sea level change doesn't just flood cities, it can also move the ground under them. up and down. Rapid sea-level rise drives increased faulting, and when we look at it relative to glacial sea-level change, one can also see it. 🧪⚒️ Link: nhess.copernicus.org/articles/26/40…

(A) Example of subdivision into undated sub-units for one of the faults (F4). TWTT – two-way travel time. (B) Correlation between displacement histories of F2, F3, and F4 faults (pink, light blue, and green dashed lines) and sea level change (the lower undulating blue line). Black dots indicate age anchor points. Between these points, the interpolated ages were calculated based on the ratio of unit thickness to time. Fault activity increases during periods of sea level change. Note that the displacements do not account for portions removed by erosion; therefore, original displacements may have been originally larger (for example, at 140 ka). Sea level curve modified after Waelbroeck et al. (2002).

Conventional wisdom for using corals as a paleo sea level indicator says that corals must live below the low tide level. This tidal pool, which has a sill above low tide, seems to break this rule!

It is probably going to be a while before I can make it back to Kumamoto after the earthquake earlier this week, but my wife sent me some pictures of our apartment. There is a big crack on the wall, but inside the only important thing that broke was the ANU mug I got when I handed in my PHD thesis.

Anyone have experience extracting microfossils out of limestone? I read that using acetic acid on crushed limestone is the way to go. I have never done this before, but am looking to learn! The limestone I am looking at is not super lithified (it is Late Pleistocene) and in theory is mostly forams.
