Abstract

The Fagradalsfjall1 and Cumbre Vieja eruptions were spectacular and, in the case of Cumbre Vieja, highly destructive. Over their course, the eruptions waxed and waned, fed lava flows, caused numerous felt earthquakes and explosions, localized from crack-fed fissure eruptions into discrete vents and cones, formed fountains up to hundreds of meters high and, for Cumbre Vieja, sent buoyant plumes of pyroclasts and gas to high altitudes. Importantly, both eruptions were visited by people from all over the world and broadcasted widely. While those visitors included many volcanologists, the majority were tourists and volcano enthusiasts, and included photographers, videographers, artists, content creators, and drone pilots. Just 5 years ago, the use of drones on volcanoes was the preserve of a few researchers only8. Today, drones are a mainstay of the photographer’s or videographer’s arsenal, whether amateur or professional. Thanks to the rapid increase in quality and availability of high-resolution digital photography equipment, and the increasing quality of smartphone cameras, it is possible for the enthusiastic amateur to capture natural phenomena in unprecedented detail. Here, we compare and contrast the Fagradalsfjall and Cumbre Vieja eruptions through the lens of the content creators who have visited these sites, with the aim of assessing the utility of non-specialist content for scientific purposes.
