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:

Special Issue “The November 23rd, 1980 Irpinia-Lucania, Southern Italy Earthquake: Insights and Reviews 40 Years Later”
2020-06-17 | in PaperThe 1980 Irpinia Earthquake with a magnitude of Mw6.9 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.

Scanning outcrops with the iPad Pro LiDAR scanner – first tests
2020-06-10 | in Software and Applications | 3 responsesAs 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.

Which are the must-read papers in tectonics and structural geology?
2020-06-09 | in PaperThe 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!

New papers on paleoseismology, earthquakes, and active tectonics (May 2020)
2020-05-02 | in Paper | one responseNormal 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.

New papers on paleoseismology, earthquakes, and active tectonics (Apr 2020)
2020-04-02 | in PaperSince 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!

Tutorial: How to make a DEM from the Slovenian LiDAR data
2020-03-26 | in Software and Applications, Teaching | 5 responsesSince 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.

How to make a beautiful flow map
2020-03-19 | in Software and Applications, TeachingOK, this is a bit off-topic, but I was asked to write a short tutorial about how to make the flow map that I posted on Twitter. Why did I actually make it? Usually I am interested in faults and earthquakes, but sometimes secondary earthquake effects such as landslides can help us to find out about seismic activity. Since my next project will be about the Alps, I am currently looking a bit into landslides, too. The map shows a large landslide close to Jena, the Dohlenstein. This slide was activated several times in the past 300 years or so, but now seems to be stable. Behind the head scarp there is a small depression. I was wondering if this is perhaps just (paleo-)drainage, or if it could be the first hint for a new sliding plane and a larger future landslide. That’s why I made the flow map – if the depression has no outflow, it’s more likely to be related to newly forming tension cracks.
