Geodynamic mantle flow model explains deformation of continental crustal blocks in northern China
Crustal structure and reconstruction of deforming plates in Northeast Asia and the Western Pacific. Credit: Nature Geoscience (2024). DOI: 10.1038/s41561-024-01513-2 Cratons are fascinating but mysterious geological formations. Cratons, known as relatively stable parts of Earth’s continental crust, have remained largely unchanged for billions of years. Although cratons have survived many geological events, some are undergoing decratonization, a process characterized by…

Are splay faults the “gateways” that trigger great continental transform earthquakes?
Credit: CC0 Public Domain The five largest continental transform earthquakes since 2000 have all occurred on tributaries of the main fault, and the two researchers predict that the next big earthquake of this type will also occur on a tributary or branch fault. Last year’s magnitude 7.8 Pazarchik earthquake in Turkey was one of several large, damaging earthquakes caused by…
