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.
Map of today’s M5.2 #earthquake near Julian in the context of regional past seismicity. This event was located near the Elsinore #fault and relatively deep at 18 km.

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 ...
"The heavy meteor bombardment during this early period caused extensive disruption and recycling of the crust.
Plate tectonics may have worked in fits and starts, triggered by meteor impacts until about 3.8 billion years ago, when meteor bombardment decreased dramatically as the early Solar System’s chaos gave way to more orderly orbits."
For more insight into the tectonic background of today’s M7.7 #earthquake in Myanmar I’d recommend this blog post and the original article on extrusion tectonics. There is also a video hiding somewhere on YouTube that illustrates this experiment perfectly.

Believe me, we have our best minds working on the "geographically" part.
It occurs to me that moving the USA somewhere else would also be an acceptable fix...

#QuizOfTheDay: Plate #Tectonics is the generally accepted scientific theory that considers the Earth's lithosphere to comprise a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago.
How many major Tectonic Plates are there?
A. 5
B. 6
C. 7
D. 8

Yes. There is no evidence of any magma chamber building. So, no volcanic eruption in the near term.
I made a quick #map of historical #seismicity for the region of today’s M7.6 #earthquake near the Cayman Islands. This left lateral strike slip event occurred on a #fault system that produced a few similar events in size & mechanism in the last decade.
(Good to see that USGS NEIC is still online!)

Can not let Santorini and the Aegean Sea get all of the attention.
Venus’ thick atmosphere holds a nitrogen puzzle: traces of an ancient world shaped by plate tectonics. New research reveals how tectonic activity may have once cycled nitrogen, hinting at a dynamic, Earth-like past before its runaway greenhouse fate. Venus may hold secrets about planetary evolution and habitability.
