What controls Victoria microplate rotation in the East African Rift?

Lake Magadi, Kenya.

This week in News & Views, Anne Glerum, postdoc at GFZ Potsdam, discusses how her numerical models support a lithosphere-driven mechanism for the rotation of large continental microplates, like Victoria in the East African Rift System. The East African Rift System (EARS) is a newly forming divergent boundary between the Nubian and Somalian plates (Fig. 1). The plate boundary system includes se ...[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]

The Sassy Scientist – Bra-Burning Bingo

The Sassy Scientist – Bra-Burning Bingo

As a first rate scientist, Kev makes a keen observation about the lack of diversity in the Augustus Love Medal nominations, but is struggling to come to a conclusion to the question: Why is there a lack of nominations for established female scientists for the Augustus Love Medal of the EGU Geodynamics Division? Dear Kev, I’m no Sherlock, but the elementary answer is: not enough EGU members n ...[Read More]

Happy blog birthday!

Happy blog birthday!

This week, the EGU Blog Team is authorised by me to buy itself a cake with 3 little candles on top to celebrate the fact that we have been blogging about geodynamics for 3 years! Hooray! We have had a particularly successful year, so let’s have a look at what happened. What did we do? At the start of this blog year, we reorganised how the blog team functions to relieve a bit of the pressure ...[Read More]
