Modification of the pattern informatics method for forecasting large earthquake events using complex eigenvectors

, 2005
Recent studies have shown that real-valued principal component analysis can be applied to earthquake fault systems for forecasting and prediction. In addition, theoretical analysis indicates that earthquake stresses may obey a wave-like equation, having ...

Reverse Detection of Short-Term Earthquake Precursors [PDF]

, 2003
We introduce a new approach to short-term earthquake prediction based on the concept of selforganization of seismically active fault networks. That approach is named "Reverse Detection of Precursors" (RDP), since it considers precursors in reverse order ...

An Overview of Tsunami Hazards in the Southwest Pacific Ocean

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...

Universal local versus unified global scaling laws in the statistics of seismicity

, 2004
The unified scaling law for earthquakes, proposed by Bak, Christensen, Danon and Scanlon, is shown to hold worldwide, as well as for areas as diverse as Japan, New Zealand, Spain or New Madrid.

World Seismic Networks and Earthquake Catalogs

Russian Journal of Earth Sciences
This paper is devoted to the review of currently functioning seismological agencies, seismic monitoring networks created, developed and supported by them, as well as earthquake catalogs produced. Particular attention is focused on international and national seismological centers and seismic networks.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Importance of small earthquakes for stress transfers and earthquake triggering

, 2004
We estimate the relative importance of small and large earthquakes for static stress changes and for earthquake triggering, assuming that earthquakes are triggered by static stress changes and that earthquakes are located on a fractal network of ...

Metamorphic Dehydration, Fluid Pressure, and the Frictional‐Viscous Transition Along Subduction Megathrusts: Case Study in Cascadia and Implications for Slow Earthquakes

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Relative plate motion in subduction zones transitions from frictional slip to viscous flow with increasing depth and temperature. The frictional‐viscous transition can control the depth extent of megathrust earthquakes and episodic tremor and slip (ETS).

Analysis of seismicity in the Haicheng-Xiuyan region based on dense array data and deep learning methodsKey points

Earthquake Science
The aftershocks of the 1975 MS7.3 Haicheng and 1999 MS5.4 Xiuyan earthquakes have persisted for a long time. The ChinArray-III dense stations, deployed in eastern North China from 2018 to 2020, increased seismic monitoring capability in the Haicheng ...

A Deep Learning Framework for Peak Ground Velocity Prediction Using Multi‐Station Velocity Waveforms: The Taiwan Transformer Shaking Alert Model (TT‐SAM)

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract This study proposes a deep‐learning–based regional earthquake early warning model, the Taiwan Transformer Shaking Alert Model (TT‐SAM). The model adopts peak ground velocity (PGV) as its primary ground shaking prediction unit, aiming to better reflect actual structural damage and thereby enhance the practical utility and accuracy of the ...
