Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A New Method of Seismic Source Parameter Estimation of a Locked-Segment Cracking Event

open access: yesGeofluids, 2022
Locked segments are widely present in the slip surface of large rock slopes and seismogenic faults of rock underground engineering. Each cracking occasion of the locked segment results in a seismic event.

震源机制对地震辐射能量估计的影响

open access: yesDizhen xuebao, 2023
利用国家地震台网和全球地震台网的宽频带远震P波波形数据,通过测定2014—2019年间国内MW≥6.0和国外MW≥6.5共105次浅源地震的辐射能量和能量震级,研究了震源机制解对辐射能量估计的影响。结果表明:① 震源机制不同导致地震能量辐射差异较大,其中走滑型地震对辐射能量的影响最大,对能量震级的平均影响因子为0.34,正断型地震对能量震级的平均影响因子为0.08,逆断型地震对能量震级的影响最小,平均影响因子为0.05;② 不同震源机制类型地震的差震级ΔM也不同,走滑型地震的ΔM为 0.31 ...

Estimating the Radiated Seismic Energy of the 2010 ML 6.4 JiaSian, Taiwan, Earthquake Using Multiple-Event Analysis

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2012
Through a proposed multiple-event analysis of teleseismic P-waves, this study investigated the radiated seismic energy and rupture process of the 2010 JiaSian earthquake. Results showed that the earthquake comprised at least two sub-events. The first sub-

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

open access: yesEarthquake Science
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 of the source.

Analysis and comparison of Fourier and Wavelet transforms: application to the study of seismic source parameters of the 2001 Arequipa Earthquake

open access: yesBoletín de Ciencias de la Tierra
This study focuses on the characterization of the June 23, 2001, Arequipa earthquake by applying the Fourier Transform (FFT) and Wavelet Transform (WT) together to estimate source parameters and radiated energy, aiming to improve seismic risk management

Coda-derived source properties estimated using local earthquakes in the Sea of Marmara, Türkiye [PDF]

open access: yesSolid Earth
Accurate estimates of the moment magnitude of earthquakes that physically measure the earthquake source energy are crucial for improving our understanding of seismic hazard in regions prone to tectonic activity. To address this demand, a method involving
