The quantity and quality of satellite-geodetic measurements of tectonic deformation have
increased dramatically over the past two decades improving our ability to observe active …

Understanding earthquake (EQ) recurrence relies on information about the timing and size
of past EQ ruptures along a given fault. Knowledge of a fault's rupture history provides …

A nearly 20-year hiatus in major seismic activity in southern California ended on 4 July 2019
with a sequence of intersecting earthquakes near the city of Ridgecrest, California. This …

Earthquakes follow a well-known power-law size relation, with smaller events occurring
much more often than larger events. Earthquake catalogs are thus dominated by small …

Aftershocks are a response to changes in stress generated by large earthquakes and
represent the most common observations of the triggering of earthquakes. The maximum …

The vibrant evolutionary patterns made by earthquake swarms are incompatible with
standard, effectively two-dimensional (2D) models for general fault architecture. We …

The NGA-West2 project database expands on its predecessor to include worldwide ground
motion data recorded from shallow crustal earthquakes in active tectonic regimes post-2000 …

We develop new empirical scaling laws for rupture width W⁠, rupture length L⁠, rupture
area A⁠, and average slip D⁠, based on a large database of rupture models. The database …

We introduce the optical ruler, an electromagnetic analog of a physical ruler, for nanoscale
displacement metrology. The optical ruler is a complex electromagnetic field in which …

The 2024 moment magnitude 7.5 Noto Peninsula (Japan) earthquake caused devastation to
communities and was generated by a complex rupture process. Using space geodetic and …
