Seafloor geodetic monitoring suggests the southwestern Kuril trench offshore Hokkaido, Japan, has accumulated substantial slip deficits through shallow plate interface coupling, which could indicate potential for a rare megathrust earthquake

Deep earthquakes in the Pacific slab subducting beneath central Japan are caused by metastable olivine phase transformation and deep dehydration, according to a 3D tomographic model of the slab velocity structure.

The study shows how ship traffic in the Baltic Sea modifies seafloor morphology and disrupts water layers, thereby increasing the mixing of oxygen, nutrients and greenhouse gases, suggesting broad impacts on Baltic marine ecosystems.

The failure stress threshold for fluid injection to activate a damaging earthquake at the Pohang site was about one order of magnitude larger than expected for natural earthquakes, according to stochastic poromechanical simulations of the fault zone

Measurements show how flat this reflective lake in Bolivia really is, despite the wind blowing across it.

Orbiters can pick up gravitational shifts thousands of kilometres below the surface.

An analysis of seismic waves propagating through Mars finds evidence that the planet has a small, solid inner core, which challenges existing planetary models.

As Earth’s magnetic field has risen, so have the conditions that helped complex life to thrive — a discovery that could aid the search for life on distant planets.

Samples from Hawaii seem to contain material that passed across the boundary between the planet’s core and its mantle, nearly 3,000 kilometres below the surface.

Hint: it’s less than 1% — a lot less.
