Fundamental questions on subsurface properties are robustly addressed through probabilistic assessment of multiple forward/inverse modelling formalisms using interrogation theory.
A synthesis of data from studies in different ocean basins reveals that the characteristics of oceanic crust are shaped by age and spreading rate.
High-resolution lidar topography reveals a long history of ancient earthquakes.
Many seismic wave models are based on an erroneous assumption about the Earth's interior. A new technique corrects this by eliminating false signals produced by models.
For decades, scientists have probed Earth's remote mantle by analyzing how seismic waves of distant earthquakes pass through it. But we are still challenged by the technique's limitations.
