Seismic recordings from the South China Sea indicate that subtle, daily tilting of shorelines due to passing internal ocean waves can be measured on land, promising new constraints on ocean dynamics.

Aftershocks and Fiber Optics
Internet cables can be transformed into a string of dense seismic sensors, and this approach has now been shown to be highly useful for quickly monitoring seismicity after major earthquakes.
Earthquake Rates Enhanced by Triggered Creep
Analysis of California earthquakes solidifies links between shaking due to remote earthquakes and increased local earthquake activity that persists for times longer than for regular aftershocks.
Groove is in the Fault
Rock sliding experiments on meter scales show groove patterns which are controlled by normal stress. This may help better understand earthquake source conditions from exhumed faults.
Frequency Dependent Plates
Rocks stretch, break, and flow, depending on how and under which conditions they are loaded. A new formulation to better capture Earth’s rheology is explored in the context of plate thickness.
The Scientist Who Connected It All
Approaching the 250th anniversary of Alexander von Humboldt’s birth, we look back at the life and legacy of “the most scientific man of his age.”
2000 Manuscripts Under the G
The outgoing Editor in Chief of Geochemistry, Geophysics, Geosystems reflects on almost a decade with the journal and expresses appreciation for all those who contributed to its success.
Richard J. O’Connell (1941–2015)
This son of a Montana sheriff discovered the fundamental rules underlying complex geophysical phenomena, and he taught others to do the same.
Subduction, Stratosphere, Starspots, and Sushi
Highlights from AGU’s joint meeting with the Japan Geophysical Union.
Earth and Space Science for the Benefit of Humanity
A collection of Commentaries published in the journals of the American Geophysical Union illuminate the deep and growing benefits of research in the Earth and space sciences for humanity.
