When you look at pottery, have you thought much about the clay used to make it? The indigenous Shoshone people of the Greater Yellowstone area sure did! The different clays used in their wares consist of minerals that can be traced back to rock types in the region and where those pieces were found tells us how far the people travelled within a region. Geo-archeological searcher Chloe Geddes tells us of her findings and explains how geology overlaps with archeology in many interesting ways.

When learning about Earth history, many of us learn about the Alfred Wegener, the Father of Plate Tectonics, but do you know about the *woman* whose discovery influenced the theory of plate tectonics? Let’s talk about Marie Tharp, the geologist and cartographer who discovered the mid-Atlantic ridge and thrust forth a new understanding of one of our planet’s most ancient processes. The story behind her discovery mirrors that of many woman scientists; her ideas dismissed by male colleagues who ultimately wound up taking credit for her work once they realized she was right all along. I for one propose we call her the Mother of Plate Tectonics and Proving Men Wrong. Download the Callin app for iOS and Android to listen to this podcast live, call in, and more!

Each grain of sand on the planet came from a rock that weathered down to almost nothing. Studying these remains helps us to piece together what the earth was like when that rock was formed, millions even billions of years ago. Now, thanks to a new technique developed by researchers in Australia, home of oldest known grain of sand, we can look back in time at the ancient settings in which these sediments were dispersed to uncover clues about Earth’s earliest tectonic processes.

There are more than 5,000 active submarine volcanoes on Earth, all varying in size and eruption style. Studying the rocks formed at these underwater vents is necessary to understanding the explosiveness of future eruptions, some of which can even burst lava and ash out of the water’s surface. As it turns out, the most explosive ones are spewing pink pumice, and exactly how pink they are is a crucial detail.

We’ve all seen those action-packed, albeit cheesy, natural disaster movies. MONSTER EARTHQUAKE! KILLER TSUNAMI! THE MOON IS CRASHING INTO THE EARTH!!!!!! With the theatrical release of Moonfall and all its scientific fallacies, it’s a perfect time to talk about Hollywood’s obsession with geological disasters. What they get wrong, what they get right, and why people love it regardless.

Mount Vesuvius decimated Pompeii nearly 2,000 years ago and has had dozens more eruptions since. Even though its most recent was way back in 1944, it’s still considered geologically active. This begs the question: when will it erupt again? By studying garnets found at volcanic deposits from eruptions dating back 10,000 years, predictions can be made about the fate of the magma currently residing 6-8km beneath the deadly volcano.

The internet is a highway lined with billboards promising enrichment, entertainment, and information. Picture a sign for shocking and exciting news on scientific discoveries… You’d want to learn more, too, right? However, following those signs too often leads down a dangerous path to misinformation and even straight up lies. How serious can this really be? Well, take it from scientists when we say: clickbait is destroying science journalism and dumbing down our population in the process.

Thanks to seismic waves, we can now see underneath the massive ice sheet that covers Greenland. Through imaging of these waves, the sub-glacial terrain was mapped to understand which areas are susceptible to more rapid flow and melting. This is a cool topic for me because it’s related to research I did on flow dynamics of the ice sheet! Back then, I used a less-accurate dataset of the ground elevation under the ice, so this is incredible because it could provide me with better results when I eventually finish the project!

In 1737, an earthquake in central Chile that went largely unreported caused a tsunami that subsequently evaded historical records. So how did we find out about it? By looking at disturbances in sand. Yeah, sand. The discovery then changes what we know about the frequency of earthquakes in this region.
