Unzen and the inclined spine

Image
Another week, another cheeky self-promoting post. This time, I have published a new paper in Solid Earth   on my research on the eruption of Unzen volcano in Japan. The project involves a volcanic spine, thousands of volcanic earthquakes, and a whole medley of analytical tools. Interested? Read on... Incandescent glow seen on the newly forming lava dome at Unzen volcano in 1991. Pyroclastic density current deposits can be seen in the foreground. These currents, also known as pyroclastic flows, were derived from collapses of the highly unstable dome. Photo credit: Fumiaki Kobayashi Let's start from the beginning. Lava spines are a curious and spectacular formation found at volcanoes around the world. These plugs of lava are squeezed out of lava domes during eruptions, grinding as they go, and eventually reaching hundreds of metres in size. One such spine grew at Unzen volcano in Japan in 1994, and is the focus of the new paper. Extensive field and experimental investigatio
