Volcanoes and earth science are a very visual field, where illustrations and sketches are critical for a targeted and simplistic understanding. In this episode we speak with scientific illustrator Annabelle Foster about the importance of accurate illustrations and schematics in Earth Science, as well as setting up her own business in this area.

Annabelle is a scientific illustrator and Earth scientist with a PhD in volcanology from Durham University, where her love for turning complex science into visual stories first began. She specialises in illustrating Earth science research, but her freelance work spans a wide range of fields, including cardiology, neuroscience, immunology, physics, and bioengineering.

Annabelle has travelled far and wide to study volcanoes up close. Her doctoral research focused on an obsidian-rich volcanic ridge in Iceland, where she investigated how obsidian can form from sintered volcanic ash, not just from rapidly cooling lava!

Based in North Yorkshire, she works with clients around the world and is dedicated to making science more accessible, visual, and inspiring. Her illustrations have appeared in academic journals, education resources, public engagement projects, and international conferences.

Every continent has a highest mountain, but every continent also has a highest volcano! Wouldn't it be incredible to climb all seven?! So let's speak to someone who has done it!

This episode we're joined by mountaineer, military veteran and volcanic climber, Ricardo Kaljouw, who recently completed the Seven Volcanic Summits challenge - to talk all about his experiences climbing these seven volcanoes. You won't believe how different each of these are!

Ricardo Kaljouw, born on May 22, 1986, in Vlissingen, Netherlands, is a distinguished Dutch alpinist and military veteran. He is known for his achievements in mountaineering, particularly for completing the Volcanic Seven Summits challenge. This feat, which involves climbing the highest volcanic peaks across all seven continents, was capped by his historic summit of Mount Sidley in Antarctica in February 2025, making him the first Dutchman to complete this challenging endeavor. He is also ranked as number 50 in the world to have completed the Volcanic Seven Summits.

Beyond his accomplishments in climbing, Kaljouw is a veteran of the Dutch Armed Forces, having served in multiple military missions. His experience in the military has shaped his approach to both mountaineering and life, instilling a sense of discipline, resilience, and determination that has propelled him through extreme challenges.

Kaljouw has climbed over 50 high-elevation volcanoes around the world, some of which are still active. His passion for volcanic exploration goes beyond the summits, as he actively shares his experiences through various platforms. Engaging with a community of fellow explorers, he teaches newcomers about the fascinating world of volcanoes.

Time to get artistic, as nature IS one of our greatest artists, but sometimes we also need human artists to help us better visualize and interpret the world around us. We're joined in this episode by nature illustrator and geologist, Vojta Hybl, as he takes us through his journey across geology and art, and how he is using art as a way of communicating the geological world with the public.

Vojta (he/him) is a nature illustrator, writer and educator based in Scotland. He works at the intersection of art and science, exploring the interconnectedness of the natural world as well as our relationship with it. Vojta studied Geology and Physical Geography at The University of Edinburgh and found his way into illustration when doing field sketches. He began communicating geology through art on Instagram as 'Rocks on Paper' in 2021. Since then, Vojta's practice has grown to include all parts of nature and he has worked on science communication and creative projects with National Museums Scotland, Dynamic Earth, The University of Edinburgh and The Nature Library.
