Understanding intraplate earthquakes

Attreyee Ghosh and edited by Jyotirmoy Paul July 8, 2020

One of the basic tenets of plate tectonics states that deformation occurs along plate boundaries while plate interiors remain almost undeformed. Intraplate earthquakes defy this principle and hence are quite enigmatic. In this week’s News and Views, Prof. Attreyee Ghosh from the Centre for Earth Sciences, Indian Institute of Science, tries to explain the …[Read More]

Imaggeo On Monday: Geoscientific selfie at the Dead Sea

Djamil Al-Halbouni July 6, 2020

This is an aerial image taken from a balloon at around 150m height, at the eastern shoreline of the Dead Sea. Such “selfies” are scientifically valuable, providing important data that help researchers to analyze the morphology of the retreating lake and investigate associated hazards like sinkholes, subsidence and landslides. The older shorelines, visible as lines …[Read More]

DE BELLO VULCANICO 40-year scientific effort of ‘predicting the unpredictable’ since the 1980 eruption of Mount Saint Helens

Mattia Pistone July 6, 2020

Volcanoes arouse emotions in the soul of men: at the same time, they are fascinating and frighten the population that lives on their slopes when they erupt (Fig. 1). Volcanoes can strike without warning and wreak horrific destruction and death. As such, in the ancient time, volcanoes discharging explosive eruptions have been interpreted as the …[Read More]

#MINERALMONDAY: Bismuth

Mike Jollands July 6, 2020

It’s not so common for us to think about pure metals as minerals, or even crystals, but just like pinocchio could be a real boy, pure metals can be minerals too. This is because, if the metal cools down from a melt very slowly, layers of metal atoms can add onto previously solidified atoms, forming …[Read More]

Scott Hotaling July 3, 2020

Did you know that glacier mice can be found at the surface of some glaciers? They’re not the tiny rodent you might be imagining, but actually little balls of moss, which appear to be full of mysteries still to be uncovered… What is a “glacier mouse”? On glaciers around the world, mostly at high-latitudes in the …[Read More]
