Viking 2 detected two possible marsquakes in 1976. New analysis links one to the same region where InSight recorded nearly 1,000 marsquakes decades later.

A Rock Avalanche Buried an Arctic Glacier. Was Climate Change to Blame?
Degrading permafrost and earlier small quakes likely weakened a rock slope until it collapsed and buried an Arctic glacier in tons of rock.

Reading Fault Stress from the Rhythm of Earthquakes
T-rate, a new Bayesian tool that reconstructs changing fault stress from earthquake rates, reveals a late stress increase before the 2008 Reno–Mogul magnitude 5.1 earthquake.

How Can We Make Better Decisions About What Lies Underground?
Geophysical data offer incomplete clues about the subsurface. Bayesian inversion turns them into plausible scenarios and shows which uncertainties matter for real-world decisions.

Tectonics and Deglaciation Govern Eastern-Southern Alps at Slow Rates
Transnational, multiproxy, and interdisciplinary datasets locate seismic hazard and show that slow-rate tectonic and deglaciation deformation overrate mantle processes in the Southern-Eastern Alps.

Fluid-Driven Reactions Restore Fault Strength Between Earthquakes
In fault gouge, fluids drive chemical healing by cementing grains, a mechanism for seismic slip in rocks frictionally expected to creep. This cohesion matters for fault stability.
