#shareEGU20: A welcome to the first virtual EGU General Assembly from EGU President Alberto Montanari

I am enjoying a positive feeling while I am writing these words to open the EGU2020 General Assembly #shareEGU20.

It is in their memory that we are looking to the future and making an effort to transform this crisis into an opportunity. I ...[Read More]

Brown Bluff is a basalt tuya located on the Tabarin Peninsula of northern Antarctica. This site supports a breeding colony of about 20,000 pairs of adelie penguins and about 550 pairs of gentoo penguins. Geologically speaking, Brown Bluff is simply fascinating. The towering bluffs were the result of an explosive volcanic eruption under ice. Large boulders have toppled from Brown Bluff to the beach ...[Read More]

As child growing up on the south coast of Devon in the UK, I never really realised that our beaches were unusual. A glorious, glowing orange-red colour, the cliffs that you can see in this photograph by Sarah Weick produced similarly red sand beaches and warm ochre soils. The bright colour is the result of the sandstone and conglomerates of these rocks, collectively called the New Red Sandstones, ...[Read More]

This is a transmitted light microscope image of a thin section – a 50-micron thick sliver of rock. This sample was collected from Jebel Hafit, a mountain which straddles the United Arab Emirates and Oman border. Jebel Hafit is approximately 900 m high and is made up of Eocene to Miocene age carbonate rocks which were mainly deposited in a shallow water, tropical setting. More specifically, this im ...[Read More]

How dangerous this island is, was demonstrated by a number of explosive eruptions in recent history, the latest of which oc ...[Read More]

The last phase of eruptive activity before this photo was taken was on October 30, 2015, which produced an ...[Read More]
