Abrasion-set limits on Himalayan gravel flux
The amount of coarse gravel transported out of the Himalayan mountains by rivers is insensitive to catchment size, because the majority of gravel sourced more than 100 kilometres upstream of the mountain front is abraded into sand before it reaches the Ganga Plain.

Rheological separation of the megathrust seismogenic zone and episodic tremor and slip
A model of the conditions required for episodic tremor and accompanying slow slip to occur, near the megathrust seismogenic zone, reconciles seemingly contradictory observations.

Hurricane intensification along United States coast suppressed during active hurricane periods
In general, if there are fewer Atlantic hurricanes, those near the US coast are more likely to intensify, whereas if there are many hurricanes, then those near the coast are more likely to weaken because of high local wind shear and low sea surface temperatures.

Measurement of the Earth tides with a MEMS gravimeter
A light-weight, low-cost microelectromechanical system gravimeter is presented with sensitivity and stability high enough to measure the elastic deformation of the Earth’s crust as a result of tidal forces, enabling many applications.
