Mechanism for seismic supershear dynamic rupture based on in-situ stress: a case study of the Palu earthquake in 2018

open access: yesGeomatics, Natural Hazards & Risk, 2022
The Palu earthquake, with a magnitude of 7.5, severely devastated the region in Central Sulawesi, Indonesia, but the mechanism of dynamic rupture considering in-situ conditions is not well understood.

Spatial distribution and focal mechanism solutions of the Wenchuan earthquake series: Results and implications [PDF]

open access: yesEarthquake Science, 2011
We relocate the spatial distribution of the devastating 12 May 2008 Wenchuan earthquake and its aftershocks. The relocation database is obtained from 89 stations deployed by the China Earthquake Administration, including 54 525 seismograms from 1 376 local earthquakes over MS3.5 between 12 May 2008 and 3 August 2008.

盈江地区构造应力场和断层识别的联合迭代式反演研究

open access: yesDizhen xuebao, 2022
搜集了盈江及其邻区5组地震序列震源机制解并反演得到该区域的构造应力场。研究结果显示:盈江地区整体主压应力以NNE向为主,主张应力以ESE向为主;但其局部应力场不完全一致,沿苏典断裂分布的主压应力轴走向随着断裂走向由北向南延伸角度逐渐向北偏移,而盈江地区的西南部,其主压应力走向更偏向于东,这可能与大盈江断裂的横向拉伸有关。此外,本研究通过应力场反演识别出了5组地震序列震源机制解的主发震断层节面的走向、倾角、滑动角及发震断层的摩擦系数,为今后该区域的地震研究及地壳动力学变迁提供了参考。

Using InSAR for evaluating the accuracy of locations and focal mechanism solutions of local earthquake catalogues

open access: yesGeophysical Journal International, 2022
SUMMARYEarthquake source parameters play a fundamental role in evaluating seismic hazard. In many countries, the relatively low accuracy of the earthquake source parameters owing to sparse seismic monitoring networks prevents accurate seismic hazard evaluation.

Seismic analysis of the Xiluodu reservoir area and insights into the geometry of seismogenic faultsKey points

open access: yesEarthquake Science, 2022
The Xiluodu (XLD) reservoir is the second largest reservoir in China and the largest in the Jinsha River basin. The occurrence of two M > 5 earthquakes after reservoir impoundment has aroused great interest among seismologists and plant operators.

2013 Seismic swarm recorded in Galati area, Romania: focal mechanism solutions [PDF]

open access: yesActa Geodaetica et Geophysica, 2016
An unusual seismic swarm started on September 23, 2013, close to Galati city, in Izvoarele region (Romania), and lasted until November 12, 2013. 406 earthquakes were recorded during several phases of seismic activity. The strongest events—a magnitude 3.9 earthquake, occurred on September 29, and two ML 3.8 shocks, occurred on October 3 and 4 ...

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...
