The Earth’s crust is made up of tectonic plates that are constantly in motion. Large, destructive earthquakes occur when accumulated energy at plate boundaries - where two plates are pushing against each other - is suddenly released.

We’re currently in open access week, and one of the things I’ve noticed has been a rash of tweets of the form “I support #OpenAccess because …”. Here is a random collection. We support #OpenAccess because #OpenScience needs good infrastructures. — @ZB_MED We support #OpenAccess because we believe that research results made possible by public funds should be accessible to everyone.

Haibin Yang, Louis Moresi and Mark Quigley provide a scaling relationship for the fault spacing in continental strike-slip shear zones.

As has been discussed here before, the recurrent laryngeal nerve (RLN) does not only innervate the larynx, but also parts of the esophagus and trachea (see this post, and in particular this comment). You can see that in this cadaver photo, in which the RLN is sending nice big visible branches into both the esophagus […]

... probably the most challenging feature in the global ocean on which to deploy ocean bottom seismometers, which need to land onto a relatively flat surface ...

Get your red-cyan glasses — you do have some, right? — and check out this glorious image. Best full-screen it, it’s worth seeing!

Kyle Manley, Tristan Salles Dietmar Müller Since roughly 1880 the Earth has warmed by 1 deg C, many times faster than any warming episode in the past 65 million years of Earth’s geological history. We will need to remove hundreds of gigatons of carbon dioxide (CO2) from the atmosphere by the end of the twenty-first century to keep global warming below 2°C within the constraints of the global carbon budget.

Three and a half days after our departure from Hobart, we arrived in just northeast of the Macquarie island and instantly proceeded with swathing – mapping the ocean floor in the north-eastern quadrant, in lines parallel to the Macquarie ridge.
