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

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…

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

Help me test some controversial hypotheses! Let's break some rocks and calculate how they break :)

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.

A M8.8 earthquake just ruptured the subduction zone offshore Russia’s Kamchatka peninsula. This is one of the world’s truly huge earthquakes, and a triggered tsunami is currently traveling across the Pacific ocean.
This same fault ruptured on July 20th in a M7.4, and last August in a M7.1.
