What happens when one of the biggest eruptions in Iceland’s history meets modern-day science?
In the latest episode of the Lava Academy Podcast, host Iain MacKinnon sits down with geologist Glen L’Estrange to explore the incredible story of the Eldgjá eruption—a volcanic event so powerful it reshaped landscapes, displaced early settlers, and left behind clues that scientists are still uncovering today.
Why You Should ListenThis episode takes you far beyond the surface of Iceland’s volcanic landscapes.
You’ll discover:
What made the Eldgjá eruption one of the largest in Iceland’s historyJust how massive a 75 km-long fissure eruption really isHow scientists reconstruct eruptions from over 1,000 years agoThe real-world impacts on people, landscapes, and even global climateWhat a similar eruption could mean for Iceland todayIt’s a fascinating blend of science, storytelling, and real-world relevance—perfect for anyone curious about volcanoes, Iceland, or the forces shaping our planet.
Meet the Guest: Glen L’EstrangeGlen is a volcanology master’s student and research assistant at the University of Iceland, currently studying some of the country’s largest historical eruptions. He also works at Lava Show as a Lava Master.
In this episode, he shares insights from his fieldwork—digging through layers of volcanic ash (tephra), camping in remote highlands, and piecing together the story of an eruption that happened over a thousand years ago.
A Glimpse Into the EpisodeThe Eldgjá eruption occurred around 937–940 AD and stretched across a fissure system roughly 75 kilometres long—over ten times larger than recent eruptions on the Reykjanes Peninsula. But what makes this episode truly compelling isn’t just the scale—it’s how scientists like Glen are able to reconstruct these events using volcanic “fingerprints” preserved in Iceland’s soil. From ash layers that act like a geological barcode to fieldwork stories involving river crossings and Icelandic weather at its worst, this episode brings both the science and the human side of volcanology to life.
More Than Just HistoryThis isn’t just a story about the past.
Understanding eruptions like Eldgjá helps scientists prepare for the future—especially in a country like Iceland, where volcanic activity is part of everyday life.
As Glen explains, modern monitoring systems give us a huge advantage—but large-scale eruptions still pose questions we don’t fully have answers to yet.

Are volcanoes unique to Earth—or are they erupting across the solar system?
In this episode of the Lava Academy Podcast, hosts Iain MacKinnon and Ragnhildur Ágústsdóttir (AKA Lady Lava) sit down with Iceland’s beloved science communicator, and author Sævar Helgi Bragason for a mind-expanding journey beyond our planet.
Together, they explore volcanic activity on Mars, Venus, and Jupiter’s moon Io, icy cryovolcanoes on distant moons, and even evidence of eruptions on Pluto. Sævar explains how gravity, internal heat, and planetary forces create volcanoes in places far beyond Earth—and what studying them teaches us about our own planet’s past and future.
The conversation also touches on Iceland’s iconic volcanoes, why eruptions inspire awe rather than fear, and how volcanoes are essential to the story of life on Earth. To top it off, Sævar shares his passion for astronomy and gives an exciting preview of the total solar eclipse visible from Iceland in August 2026—an event he describes as one of nature’s most powerful experiences.

In our latest episode of the Lava Academy Podcast, we welcome the multi-talented geoscientist and marketing strategist Jessica Poteet for a fascinating conversation about Iceland’s fiery landscape, her personal journey, and the unique challenges of living on one of the world’s most volcanically active islands.
Jessica, originally from the United States, first came to Iceland on a hiking trip—and was so captivated by the raw beauty of the land that she quit her job in Silicon Valley and bought a one-way ticket back. Since then, she has built a thriving career in travel technology and communications, while also sharing her deep passion for geology as an admin of the hugely popular Iceland Geology Facebook group, which now has more than 160,000 members worldwide.
In the episode, Jessica explains what makes Iceland such a geological treasure compared to other volcanic regions, and why recent eruptions on the Reykjanes Peninsula are both scientifically significant and a reminder of the power beneath our feet. She also talks about her mission to combat misinformation during eruptions, offering science-based insights while encouraging respect for nature and safety.

Geologist Sean Willsey discusses Icelandic volcanic wonders
In this second episode of The Lava Academy by Lava Show, we sit down with Sean Willsey, a geology professor at the College of Southern Idaho and creator of the popular YouTube channel Geology Explained. Sean shares his deep connection to Iceland, what keeps pulling him back year after year, and how the recent eruption cycles on the Reykjanes Peninsula have rewritten our understanding of Icelandic geology.
Listeners will gain insight into the dramatic seismic activity and eruptions near Grindavík, the science behind magma movement and ground deformation, and how Iceland is balancing hazard mitigation with life on a volcanic island. Sean also reflects on how volcanic education, including live lava experiences like Lava Show, can build global awareness and fascination with the Earth’s dynamic processes.
The conversation covers real-time eruption response, shifting magma conduits, how the 2021–2024 eruptions compare to Iceland’s geologic past, and whether we’re entering a new volcanic era.
This is a must-listen episode for volcano-watchers, educators, and anyone curious about the incredible forces shaping Iceland’s ever-evolving landscape.

In the debut episode of Lava Academy by Lava Show, geologist Madison MacKenzie shares her personal journey from growing up near volcanoes in the U.S. and Japan to studying and working in Iceland’s fiery landscape. She walks listeners through volcanic fundamentals — what volcanoes are, how they form and erupt, and what makes Iceland one of the world’s most geologically active regions. Madison explains how different types of lava and eruption styles shape volcanoes, and why Iceland's location on a tectonic boundary and above a hotspot creates such unique volcanic activity.The episode dives into lava types, eruption styles, and how scientists monitor volcanic behavior through seismic activity and satellite data. Madison also breaks down myths about eruptions, noting that many are mild and even beneficial. Hosts: Ian MacKinnon, and Jon Heidar Ragnheidarson
