Is there accelerated crustal deformation before large earthquakes? A case study of strong intra-plate earthquakes in China

The existence of a detectable precursory phase of fault slip preceding major earthquakes has been a subject of ongoing debate for decades. A recent study (Bletery and Nocquet, 2023) demonstrated exponential...

Probabilistic seismic hazard analysis for the northern segment of the North-South Seismic Belt in China based on improved spatial smoothing and fault source model integration

The northern segment of the North-South Seismic Belt is characterized by intense crustal deformation, well-developed active tectonics, and frequent occurrences of strong earthquakes. Therefore, conducting...

High-resolution 3D shallow crustal structure of Urumqi foreland thrust tectonic belt, northern Tianshan, based on ambient noise tomography

The Urumqi foreland thrust tectonic belt exhibits complex geological structures and strong seismicity. Imaging its shallow crustal structure is of great significance for understanding its tectonic mechanism...

Developing successful international collaborations in Earth Science research

I offer suggestions to increase the probability of success of an international research project. Collaborative studies often produce more innovative and transformative scientific results than work done...

Talking effectively about science

Science communication requires talking with diverse audiences. Here, I pontificate, and then visit seven distinct settings, punctuated by some of my own fiascos, in the hope others might fare better...

The nature of the Kumkol Basin, northern margin of Qinghai-Xizang Plateau constraints from seismic velocity structure

The Kumkol Basin, situated in the northern margin of the Qinghai-Xizang Plateau, provides a unique window into understanding the dynamic mechanisms driving the plateau’s northern expansion. However,...

Viscoelastic Coulomb stress from historical earthquakes on the 2022 Luding MS6.8 earthquake and its static stress triggering on neighboring faults

We investigated the influence of historical earthquakes on the 2022 Luding MS6.8 earthquake and its subsequent effects. We computed the viscoelastic Coulomb stress changes induced by these historical...

Amplification of thickness and stratigraphy of loess deposit on seismic ground motion in the Yellow River Basin

The widely distributed loess deposits in the Yellow River Basin exhibit unique engineering geological characteristics. The variations in their thickness and stratigraphic structure significantly amplify...

Determination of radiated energy and energy-moment ratio for the 2025 Dingri, Xizang M6.8 earthquake

Radiated seismic energy is a quantitative characteristic of an earthquake that depends not only on the initial and final stresses, but also on the rupture history, and reflects the dynamic characteristics...

A fault source-based algorithm for probabilistic analysis of seismic hazard incorporating the rupture scale of large earthquakes

In this study, a seismic hazard algorithm was developed, coupled with a multi-source model. The algorithm can calculate the seismic hazard of 2D planar sources and 3D fault sources. A point source model...

Simulation of acoustic waves in 2D circular regions using the multi-block structured grid finite-difference method

Global acoustic simulations are significant in revealing the internal and physical structure of the Earth. However, due to the limited flexibility of grids and the difficulties in handling boundaries,...

High-resolution tomography of P-wave velocity structures in the Haicheng region: Implications for the seismogenesis of the 1975 MS7.3 Haicheng earthquake

The 1975 Haicheng earthquake represents the first successful prediction of a major earthquake in China and is the only earthquake forecast officially recognized by the United Nations. Understanding...

Co-existing fast and slow afterslip processes following the 2015 Gorkha (MW7.8) earthquake resolved by full time-series inversion

The 2015 Gorkha (MW=7.8) earthquake ruptured the downdip portion of the Main Himalayan Thrust. Afterslip following this event provides valuable insights into the frictional properties on the thrust...

Waveform inversion of the fault zone structure based on generalized teleseismic wave records

High resolution imaging of the fault zone structure is crucial to understanding the characteristics of strong earthquake activity and the deep seismogenic environment. In seismological studies, the...

Crustal structure of the central Cathaysia block in South China derived from receiver functions

The Cathaysia block in Southeast China has undergone complex compression, collision and tectonic evolution processes, which have led to the formation of rich granites and polymetallic ores. However,...

Basic processing of the InSight seismic data from Mars for further seismological research

The InSight mission has obtained seismic data from Mars, offering new insights into the planet’s internal structure and seismic activity. However, the raw data released to the public contain various...

Performance evaluation of the waveform stacking-based microseismic location method in the southern Sichuan Basin of China

Seismic source locations can characterize the spatial and temporal distributions of seismic sources, and can provide important basic data for earthquake disaster monitoring, fault activity characterization,...

The dilatancy-diffusion hypothesis, earthquake prediction, and operational earthquake forecasting: In memory of Professor Amos Nur on the 50th Anniversary of the 1975 Haicheng Earthquake

Dilatancy is referred to the phenomenon of volume increase that occurs when a material is deformed. Dilatancy theory originated in geomechanics for the study of the behavior of granular materials. Later...

CrazyBeachball: A MATLAB GUI-based software package for focal mechanism inversion

We present CrazyBeachball, a MATLAB-based graphical user interface (GUI) software package designed for focal mechanism inversion using P-wave first-motion polarity and S/P amplitude ratio data. CrazyBeachball...

Determination of rupture directivity of the 2024 Feidong M4.7 earthquake using one single near-source station

Determining the rupture directivity for small earthquakes is challenging due to the small source dimension and limited resolution of far-field observations. In recent years, the burst of near-source...

High-resolution 3D S-wave velocity structure in northwestern Sichuan-Yunnan Block derived from ambient noise tomography

The Sichuan-Yunnan Block is located on the southeastern margin of the Qinghai-Xizang Plateau and has frequent seismic activity on the western border, posing a potential threat to human society and economic...

Foreshocks of the 2016 MS5.1 Yunlong earthquake in Western Yunnan, China, and implications for earthquake nucleation

Monitoring the evolution of foreshocks can be a valuable way to analyze the nucleation process. Foreshocks accompanying moderate mainshocks have been recorded in the west of Yunnan Province, China....

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

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...
