Massive melting of Caucasus glaciers

Massive melting of Caucasus glaciers

The Caucasus is one of the most studied glacierized regions in the world (see previous Cryoblogs on Caucasus glaciers here and here). In this week’s blog, Levan Tielidze tells us about the health of the Greater Caucasus glaciers. His first study published this year indicates that the rate of decline in glacier extent between 2000 and 2020 in the Greater Caucasus is four times higher than it was be ...[Read More]

Investigating earthquake activity of the 2018 Kīlauea Volcano eruption

Photograph of Kīlauea’s summit, Halema’uma’u Crater, partway through the 2018 eruption. The seismic events at the summit and associated eruptive activity greatly changed the structure of the summit and surrounding region. Photograph by Hawaiian Volcano Observatory on June 12, 2018 (https://www.usgs.gov/media/images/k-lauea-volcano-halema-uma-u-crater-0).

Both earthquakes and research project directions can be hard to predict. This week Becky Fildes, a graduate student at UC Davis, takes us on a journey of how she came to study earthquake behavior in Hawaii during an active volcanic eruption and how our understanding of caldera collapses can be further improved. In my first year of graduate school in 2017, I had started studying earthquake statisti ...[Read More]

Crater Glacier: A story of renewal in the aftermath of destruction

Crater Glacier: A story of renewal in the aftermath of destruction

Crater Glacier, located on Mount St. Helens, Washington State, U.S., tells a tale of renewal. The catastrophic and deadly May 18th, 1980 eruption of the volcano created, among other things, a deep horseshoe-shaped, north-facing crater and obliterated most of the glaciers that resided on the volcano’s slopes. By a decade and a half later, it was clear that a glacier had formed in this unlikely loca ...[Read More]

The Sassy Scientist – The Doctor Is In

The Sassy Scientist – The Doctor Is In

There are no stupid questions. How many times have we heard that from colleagues and in classrooms? Obviously an exceedingly sizeable chunk of our community does not receive stupid questions often enough. Even silly questions have their merits though, and obviously they deserve an answer, at least to avoid them being asked in the future. My very busy mailbox has recently seen a staggering increase ...[Read More]

The strangest rock you’ve probably never heard of

The strangest rock you’ve probably never heard of

In this blog I’m going to talk a bit about one of my favourite rocks – the strangest rock you’ve probably never heard of – listvenite. Listvenite (sometimes spelt listwanite or listwaenite) is the product of a chemical reaction between peridotite and carbon dioxide, and it is truly strange! I first came across listvenites working on the Semail Ophiolite, Oman, during my PhD. The Semail Ophiolite i ...[Read More]

Why do some slabs stagnate?

Why do some slabs stagnate?

Mechanisms for stab stagnation are essential for understanding the mantle circulation patterns. This week, Diandian Peng, a graduate student from University of Illinois explores how dynamic pressure gradients can pull the slabs sideways stagnating them at the Mantle Transition Zone. Seismic imaging provides critical constraints on the structure and evolution of subducted slabs. Numerous tomographi ...[Read More]
