What causes intraplate deformation in South America? Andean topography & geologic structures point to flat slab subduction, ridge subduction, tectonic inheritance. #Andes #foreland #basin #geodynamics #subduction @txgeosciences @UNLVGeoscience @TAMUArtSci pubs.geoscienceworld.org/gsa…

Shallow #earthquakes in the #Andes:
🔸What's going on in #Ecuador?? 😬
🔸Hints at #SlipPartitioning in the north and south. 🥰
🔸Northern #Peru is awfully quiet! And also seem to have been cheated out of its rightful share of #volcanoes. 🤨

Any geoscience/hydrology scientific illustrators out there? Might have funding to help me build educational content for the citizens of New Mexico all about water resources! DM me if interested!

Check out the hairpin turns in the Uraricoera and Takutu rivers in the northern Amazonian state of Roraima. These rivers formerly drained north into Guyana and now drain south into the Branco and then Negro rivers.

Yes, the Casiquiare canal is a case of ongoing river capture as the upper Negro captures the upper Orinoco.
The Amazon basin is continuing to expand along most of its northern margin.

Pedro Val (@topoerosion) liked studying geology. But when he learned about how tectonic activity can change the flow of rivers, he “didn’t want to know about anything else.” @theAGU

River drainage networks of England show the effects of both tectonics and erosion, with many smaller basins draining to the periphery, but the development of some larger interior basins by river capture, as in the Trent and Severn basins.

Also environmental conditions in the past. Nothing in the Amazon makes sense except in light of the Pebas megawetlands that covered over 1 million sq km from 22-10 million years ago.
