Capturing the Epistemic Uncertainty in Subduction Earthquake Rupture Parameters

ABSTRACT Subduction earthquakes are highly destructive and can trigger devastating tsunamis, highlighting the need for a consistent probabilistic seismic-tsunami hazard assessment. However, current approaches treat both hazards separately: tsunami models use static coseismic slip...

Exhumation of Grand Canyon’s basement along the Great Escarpment of Laurentia

The Grand Canyon encompasses two billion years of Earth history, but more than half this record is absent across a regionally extensive erosional surface known as the Great Unconformity. This enigmatic surface has been linked to multi-phase regional tectonics accompanying superco...

Epitactic Growthduring the Fluid-Driven Aragonite-to-CalciteTransformation

Abstract Aragonite and calcite (CaCO3) are the most abundant polymorphs of calcium carbonate in the Earth’s crust and are relevant industrial minerals. The factors that control the solid-state transformation of aragonite, the high-pressure polymorph, into calcite, the stable poly...
