By accounting for the physics of subduction paired with AI-assisted manifold detection, this work is able to predict an earthquake in New Zealand's Hikurangi trench one week early and extend predictability limits to 5-6 weeks with decadal repeatability, suggesting the fundamental determinism of the suggested mechanism through which physics-based seismic forecasting is possible.
Abstract
Slow slip events within subduction zones offer a unique window into earthquake prediction. The subducting plate drives dehydration reactions in the fault, causing cyclical slip and observable surface displacements. Earthquake footprints can then be identified in these displacement series through coupling the multi-physics governing the subduction process with regional seismic activity. However, data noise and traditional filtering methods obscure the underlying mechanisms. Here, we alleviate this constraint with our physics-based attractor. By accounting for the physics of subduction paired with AI-assisted manifold detection, we are able to predict an earthquake in New Zealand's Hikurangi trench one week early. Additionally, predictability limits extend to 5-6 weeks with decadal repeatability, pointing to the fundamental determinism of the suggested mechanism through which physics-based seismic forecasting is possible.
Earthquake swarms provide a natural window into fault response to transient perturbations, yet their driving processes are commonly interpreted using fluid-driven and aseismic-slip-driven end-member models. Intraplate swarms offer a unique setting to test these models because low secular tectonic loading heightens the...

Foreshock activity is a key consideration in traffic-light protocol (TLP) to mitigate seismic risk from injection-induced earthquakes (IIEs). However, the seismogenic processes of IIE foreshocks remain poorly understood. Using an enhanced western Canada catalog (2014-2024), we analyzed 77 IIE sequences to statistically...

Slow earthquakes, including episodic tremor and slip (ETS), are highly sensitive to small stress perturbations, yet their links to tectonic and non‐tectonic forcings remain unclear. Previous studies suggest that annual hydrological cycle dominates the tremor seasonal behavior in northern Cascadia. But over a longer tim...

Crustal permeability can be created through microearthquakes as observed at field and laboratory scales. The respective roles of seismic and aseismic slip in governing permeability evolution remain ill‐constrained. Here, we present observations of controlled pore pressure stepping experiments designed to distinguish th...

Earthquakes at subduction zones are among the most powerful natural events on Earth. During the interseismic, coseismic, and postseismic phases, interseismic coupling, co- and postseismic slip along the megathrust, and viscoelastic relaxation in the mantle produce the observed surface displacements. Different combinati...
Earthquakes exhibit well-documented statistical regularities at the catalogue level, such as the Gutenberg–Richter magnitude–frequency relation and the Omori–Utsu aftershock decay, often interpreted as signatures of seismicity as a driven, dissipative system far from thermodynamic equilibrium. However, whether comparab...
