In the last months two paroxysmal explosive eruptions took place at Stromboli volcano: the first one, totally unexpected, on 3rd July (Video 1) that sadly cost the life of a person and the second and, currently, last one about three weeks ago, on the 28th August (Video 2). Today we try to answer a couple …[Read More]

#mineralmonday: tiptopite
#mineralmonday: your weekly* dose of obscure mineralogy, every Monday** [*not guaranteed; **or possibly Tuesday-Sunday] What is it? Tiptopite: K2Na1.5Ca0.5Li3Be6(PO4)6(OH)2•(H2O) What’s it made of? Take a deep breath and recite after me: potassium, sodium, calcium, lithium, beryllium, phosphorus, oxygen and water (H2O). Is it pretty? Yes, it’s a beautiful fibrous mineral. You wouldn’t put it on …[Read More]

Imaggeo on Mondays: How do Earth’s Northern Lights form?
Aurora Borealis, which means Northern Lights are caused by electrically charged particles from the sun, which enter the Earth’s atmosphere and collide with gases such as oxygen and nitrogen. When the charged particles are blown towards the Earth by the solar wind, they are largely deflected by the Earth’s magnetic field. However, the Earth’s magnetic …[Read More]

Climate Change & Cryosphere – Why is the Arctic sea-ice cover retreating?
The Arctic Ocean surface is darkening as its sea-ice cover is shrinking. The exact processes driving the ongoing sea-ice loss are far from being totally understood. In this post, we will investigate the different causes of the recent retreat of the Arctic sea-ice cover, using the most updated literature… Arctic sea ice is disappearing Due …[Read More]

A brighter future for the Arctic
This is a follow-up from a previous publication. Recently, a new analysis of the impact of Black Carbon in the Arctic was conducted within a European Union Action. “Difficulty in evaluating, or even discerning, a particular landscape is related to the distance a culture has traveled from its own ancestral landscape. As temperate-zone people, we …[Read More]
