This time we have a number of studies on historical earthquakes, active tectonics studies from all around the world, a view review and methods articles, and plenty of tsunami stuff. Make sure to check out the new book on the geological record of extreme waves! Enjoy reading and let us know in case we’ve missed something.

Time is flying, it feels as if I had posted the last paper updated just yesterday. However, a quick glance at the list shows that there are quite a few new studies that cover paleoseismology, seismic hazard, earthquake geology, etc. Let me know if I’ve missed something cool. Stay safe!

On 23 June, 2020, a magnitude 7.4 subduction earthquake struck western Mexico and let the earthquake early warning sirens sound in the capital. Reportedly, ten people lost their lives and thousands of houses were damaged in Oaxaca. Our colleagues Magda Velázquez-Bucio, Sabina Porfido, and Alessandro Michetti have put together a report on the Earthquake Environmental Effects of this event in English and Spanish:

The 1980 Irpinia Earthquake with a magnitude of M_w6.9 was one of the strongest and deadliest earthquakes in Italy in the 20th Century. Now, 40 years later, a special issue is dedicated to this event. Guest editors Sabina Porfido, Giuliana Alessio, Germana Gaudiosi, Rosa Nappi, and Alessandro Michetti invited papers for their special issue in Geosciences. Deadline for submission is 30 October, 2020.

As soon as I learned that the new iPad Pro comes with a LiDAR scanner I knew I would have to check how useful it is. Luckily, Kamil was able to buy one for our group. So we (Georg and myself) tested the 11″ version on an outcrop right next to our institute and I also scanned the way back to the office. I used the app LiDAR Scanner 3D. The full version costs 0.99 € and allows you to save and export the models as USDZ, OBJ, STL, and PLY files. I used CloudCompare to check the data.

The Tectonics and Structural Geology Division of EGU (TS) has started a great thing: They are asking the community to name 3-5 must-read papers in their field. This could be really old fundamental stuff or ground-breaking new research – whatever you think everyone in Tectonics & StructGeol should read. The TS team will then select the 40-50 most-voted papers, discuss each of them within the TS community on a public platform on a fortnightly basis, write a summary of each paper and its discussion, and create a compilation of the TS “Must-read” papers that will be permanently archived on EarthArXiv. You can place your vote here or read the blog post on how it works here. Thanks to Silvia Crosetto for pointing me to this cool initiative!

It looks like publishing hasn’t been affected much by the Corona situation, this month’s list is probably the longest we’ve ever had. Enjoy reading and stay safe!

Normal life has come to a halt, but publishing papers apparently not. Here’s a lot of stuff to read at home: nice remote sensing studies, very cool field observations (good old days), an entire trilogy by Dirk Scherler and Wolfgang Schwanghart on drainage divides, and much more. Enjoy reading, tell me if I’ve missed something, and stay safe.

Since we are all (?) sitting at home and waiting for the situation to improve, this may be a good chance to catch up with the latest literature. Alas, new papers are published without mercy every month, and March was no different. Here are the latest ones on paleoseismology., active tectonics, and large earthquakes. Stay safe!

Since I can’t go to the field right now, I am stuck with analyzing the amazing LiDAR data from Slovenia. We have 1 m resolution data covering the entire country and oh my god it’s great for active tectonics research. But how do you actually make a DEM from the data? Here’s a quick guide using free software only.
