#Earthday in the Silesian Planetarium (last Saturday) I told, among others, about eigenfrequency, i.e. why during mining tremors they nod chandeliers and not buildings, and how I translate it into earthquake research in caves #SciComm

Exploring a #cave by #climbing is the top tier of initiation. Clip from one of the three chimneys we climbed recently in one of the Tatra Mountains caves. From dozens and hundreds of days underground, days like this are remembered forever

Our paper, discussing the curious case of a short #fault scarp in the Podhale Basin and its Implications for the #Quaternary geodynamics of the Western #Carpathians, is now out. Link with 50 days of access authors.elsevier.com/a/1mJha,3sl42u… @paleoseismicity.bsky.social

Hot off the press📢 Some fault doesn't want to behave properly Read our story about the curious case of a short fault scarp in the Podhale Basin, Carpathians🇵🇱 That was quite a challenge for us: first to interpret it and later publish… www.sciencedirect.com:5037/science/arti...

Last week, I had the pleasure of organizing in the #Tatra Mts. 59 Polish speleological symposium. Inspiring invited lectures, great talks, and most importantly, discussions in the field where we shared the last decade of our research😁I am happy we could award 4 #ECR grants

There are still a few weeks left to apply for the postdoc position in my @NCN_PL project.👇 You can model using #FEM OR you're interested in #seismology OR structural resistance to #seismic waves? Help me test some controversial hypotheses! Let's break some rocks and calculate how they break :)

Here is the 50-day free access link authors.elsevier.com/c/1lUJp8RViAsze In contrast to previouse research, we show that even small #glaciers (2km long) can produce #microtextures on quartz #grains; hence, even small glaciers can be “caught” in depositional record via #SEM and reconstructed.
