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]

This year I was lucky enough to be part of International Ocean Discovery Program (IODP) Expedition 390 – South Atlantic Transect I – aboard the research vessel JOIDES Resolution which spent two months, from April to June, out in the South Atlantic, drilling into and sampling the upper oceanic crust and sediments. I sailed as a petrologist and was responsible for describing how the basa ...[Read More]

In simple words, the volcanic risk (R) can be defined as R = Value × Vulnerability × Hazard. The value is a figure that varies according to the total number of population and / or infrastructures at risk during a volcanic eruption, vulnerability is the percentage of value at risk for a given volcanic event and the hazard is the probability that a certain place may be affected by a determined hazar ...[Read More]
