The Sassy Scientist – The Story of Plate Tectonics

The Sassy Scientist – The Story of Plate Tectonics

As a new coping mechanism with reality, Sascha has been digging into some science history and asked: How did scientists discover plate tectonics? Dear Sascha, I do enjoy a good walk on the memory lane of scientific discoveries. You might know by now that great insight is gained when we look at data with fresh eyes. Hence, lots of advances in certain narrow scientific fields come from outsiders. In ...[Read More]

Advanced geodynamic models of giant earthquakes

Advanced geodynamic models of giant earthquakes

Though giant earthquakes are disastrous, they provide essential information to investigate earthquake physics. In this week’s news and views, Thyagarajulu Gollapalli, a PhD student jointly from the Monash University and the Indian Institute of Technology, Bombay, discusses our present understanding of such big earthquakes and how advanced numerical models will help to get a more precise picture of ...[Read More]

The Sassy Scientist – The Cricetinae Model

The Sassy Scientist – The Cricetinae Model

Despite workshops and seminars and conference sessions and Zoom colloquia, of which Geraldine has attended many, one big question remains in geophysics: What drives plate tectonics? Dear Geraldine, Slab pull? Ridge push? Mantle drag? Continental keels? Super plumes? Mantle wind? Expanding Earth? God? Nope, there is only one explanation that truly fits the data and passes the common sense test: The ...[Read More]

Understanding intraplate earthquakes

Understanding intraplate earthquakes

  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 reasons behind intraplate ea ...[Read More]
