This photo was taken during a fieldwork campaign following the mainshock of the deadly seismic sequence that struck central Italy starting from 24 August 2016. The magnitude 6.2 earthquake severely damaged nearby towns, claimed more than 290 lives and injured nearly 400 people in its wake. As a geologist from the National Institute of Geophysics and Volcanology, I was in charge of measuring the ma ...[Read More]

Geopolicy: Combating plastic pollution – research, engagement and the EU Plastic Strategy

Awareness around the prevalence of plastic pollution, particularly in our oceans, has been growing over the last few years. This is not surprising considering that plastic production has surged from 15 million tonnes in 1964 to 311 million tonnes in 2014 and models have shown that this number will double again within the next 20 years in a business as usual scenario. Furthermore, research conducte ...[Read More]

Image of the Week – The world in a grain of cryoconite

Microbes growing on glaciers are recognized for their importance in accelerating glacier melting by darkening their surface and for maintaining biogeochemical cycles in Earth’s largest freshwater ecosystem. However, the microbial biodiversity of glaciers remains mysterious. Today, new DNA sequencing techniques are helping to reveal glaciers as icy hotspots of biodiversity. To see a world in a grai ...[Read More]

Image of the week – Skiing, a myth for our grandchildren?

Ski or water ski? Carnival season is typically when many drive straight to the mountains to indulge in their favorite winter sport. However, by the end of the century, models seem to predict a very different future for Carnival, with a drastic reduction in the number of snow days we get per year. This could render winter skiing something of the past, a bedtime story we tell our grandchildren at ni ...[Read More]
