Maxwell et al investigate fossil coral reefs on Luzon Island in the Philippines to determine past relative sea level and tectonic uplift rate. They conclude that it is 1.17 mm/yr, based on analysis of the MIS 5e terrace, currently at 155 m.

#Tectonics as inspiring as ever. makes me want to incorporate a lot more extended technique, and a lot more performance, into what I do. there’s a bit of both in The Vallum but I feel like that’s probably the direction I want to go next with solo stuff

new string collective absolutely fantastic at #Tectonics. really beautiful stuff.

A great first day of #Tectonics yesterday in Glasgow. Lots of amazing music, but a particular highlight for me was Rachel Musson and Mark Sanders’ improvisatory collaboration with the BBC Scottish Symphony Orchestra: sometimes fierce and invocatory, and at others tender and brooding.

Lovely to meet @jules_rawlinson too!

Looking forward to the surprises today’s second day will inevitably bring. Was anyone else there?

North America is dripping from below, geoscientists discover

Researchers have discovered that the underside of the North American continent is dripping away in blobs of rock—and that the remnants of a tectonic plate sinking in Earth's mantle may be the reason why.

Modelling suggests that Earth's first crust, which fractionated from a magma ocean, would have had a similar trace element composition to modern continental crust: in other words, this signature is not a reliable marker of subduction and plate tectonics on the young Earth.

Study reveals 'flawed argument' in debate over when plate tectonics began

You don't need plate tectonics to get continental crust that looks modern, a new study finds.

Tectonic–climatic interaction (Climatology 🌍)

Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis, volcanism, and erosion, while relevant climatic processes include atmospheric circulation, orographic lift, monsoon circulation and the rain shadow effect. As the geological ...
