Earth SciShow

In this episode of Earth Scishow, MrEarthGuy talks about a new study that reveals how the evolution of tree roots over 300 million years ago triggered a series of mass extinctions in the ancient oceans. Learn how this process, known as eutrophication, is similar to what happens today when pollution creates dead zones in the water. Discover how this discovery sheds new light on a volatile period in Earth's pre-history and what it means for our present and future. Tune in to Earth Scishow, the podcast where we explore the latest discoveries and controversies in Earth sciences.

The epiosde discusses on a recent study that analyzed the Tonga underwater volcanic eruption that occurred on January 15th, 2022. The eruption was the most powerful natural explosion in over a century, triggering a tsunami hundreds of feet high. The researchers used satellite data, field observations, and computer simulations to estimate the strength of the eruption, the height of the tsunami waves, and the factors that influenced the impacts on the islands of Tonga and other regions. The article also discusses the implications of the study for understanding and preparing for future submarine volcanic eruptions.

In this episode of Earth SciShow we take a trip into the past by exploring how all walking animals are part of a larger group of sarcopterygians who's story begins 100s of millions of years ago. From the smallest creatures to the largest mammals, we all have a unique story and it can be traced back through our ancestral genetics.

This episode is about a recent paper that proposes a new method to predict tsunamis using sound waves generated by underwater earthquakes. The method uses hydrophones to record the sound waves and a computational model to estimate the earthquake features and the tsunami size. The method is fast, accurate, and low-cost compared to other methods that rely on water level measurements. The authors have tested their method with real data from past tsunami events and are working on improving it further.

In this episode of Earth SciShow, we explore the extraordinary eruption of the Hunga Tonga–Hunga Haʻapai volcano in January 2022, which created the tallest volcanic plume ever recorded. We talk to Dr Simon Proud, a senior scientist at Oxford University and one of the authors of a new study that used satellite images and a technique called 'the parallax effect' to measure the height of the plume. We also discuss the implications of this eruption for the global stratospheric composition and climate.

In this episode of Earth SciShow, we explore a groundbreaking study that reveals the secrets of Mars' core using seismic data from the InSight mission. We discuss how the core's size, density and composition shed light on the formation and evolution of the red planet and other rocky worlds. Join us as we dive into the fascinating interior of Mars and learn more about its history and mysteries.
