The Icelandic eruptions of 2021 and 2022 originated in the Reykjanes peninsula, characterized by the Krýsuvík-Trölladyngja system, one of the five volcanic systems present along the peninsula. This peninsula is a leaky transform fault, characterized by episodic rifts and associated volcanism. The last two years have brought about some of the most momentous volcanic eruptions in recent history. The ...[Read More]

In the recent past, a lot of effort has been directed toward evaluating the consequences of the rapidly rising global temperatures. Among them, one very alarming consequence is ocean acidification (Fauville et al, 2012; Gatusso et al, 2015). Ocean acidification is the direct result of atmospheric CO2 increase caused in part by anthropogenic activities such as burning fossil fuels for energy activi ...[Read More]

Living with a Volcano

Living with a Volcano
Mount Nyiragongo Lava Lake, from Vulkane.net

Since ancient times, the growth of populations has been strongly combined with the presence of volcanoes, due to their ability to provide nutrients to soils (and so to agriculture) and resource extraction. One great example is described in our blog post about Volcanoes and wine. However, living near a volcano has its (obvious) drawbacks, starting with lava flows (see the recent Cumbre Vieja erupti ...[Read More]
