Rotational motions of the Ms7.0 Jiuzhaigou earthquake with ground tilt data

Science China Earth Sciences, 2019
Observation and research of rotational motions induced by earthquake has been ignored in the past decades due to the lack of understanding of important ground rotational motions and practical difficulty involved in directly measuring the rotational components. Currently, there is a paucity of methods to directly measure rotational motions in China. The

MULTIFRACTAL FLUCTUATIONS OF JIUZHAIGOU TOURISTS BEFORE AND AFTER WENCHUAN EARTHQUAKE

Fractals, 2013
In this work, multifractal methods have been successfully used to characterize the temporal fluctuations of daily Jiuzhai Valley domestic and foreign tourists before and after Wenchuan earthquake in China. We used multifractal detrending moving average method (MF-DMA). It showed that Jiuzhai Valley tourism markets are characterized by long-term memory

Confirmation and Characterization of the Rupture Model of the 2017 Ms 7.0 Jiuzhaigou, China, Earthquake

Seismological Research Letters, 2021
AbstractOn 8 August 2017, an Ms 7.0 earthquake struck the Jiuzhaigou town, Sichuan Province, China, rupturing an unmapped fault, which is adjacent to the Maqu seismic gap in the Min Shan uplift zone in the easternmost part of the Bayan Har block. Having summarized the previous studies on the source of this earthquake, we confirmed the rupture model by ...

Research on the estimation of the real-time population in an earthquake area based on phone signals: A case study of the Jiuzhaigou earthquake

Earth Science Informatics, 2019
After an earthquake, the goal of emergency rescue work is to minimize the number of casualties and save lives. The most important initial task is the rapid assessment of the number of earthquake casualties. At present, the rapid assessment of casualties relies primarily on census data rather than real-time population data in an earthquake area ...

Response of tree rings to earthquakes during the past 350 years at Jiuzhaigou in the eastern Tibet

Science of The Total Environment, 2020
Trees growing in the tectonically active and climatically sensitive regions, such as the Tibetan Plateau, frequently suffer damage from strong earthquakes and extreme hydro-climatic events. Spruce trees in the Jiuzhaigou National Park exhibited abrupt periods of growth suppression with durations of 3-9 years, which was demonstrated to have recorded ...

Territorial suitability assessment and function zoning in the Jiuzhaigou earthquake-stricken area

Journal of Mountain Science, 2019
An earthquake in the Jiuzhaigou area caused numerous secondary disasters, such as rolling stones, land collapse, landslides and debris flow, which badly affected the safety of human settlements and influenced the spatial layout of the post-disaster reconstruction.

Quantitative assessment of the impact of earthquake-induced geohazards on natural landscapes in Jiuzhaigou Valley

Journal of Mountain Science, 2019
Many natural landscapes that lie in high mountain regions are highly susceptible to geological hazards, and their values and integrity are strongly threatened by the hazards. A preliminary framework was proposed to undertake a quantitative assessment of the impact of earthquake-induced geological hazards on the natural landscapes.

Earthquake-triggered landslides affecting a UNESCO Natural Site: the 2017 Jiuzhaigou Earthquake in the World National Park, China

Journal of Mountain Science, 2018
On August 8th, 2017, an Ms 7.0 magnitude earthquake occurred in Jiuzhaigou County, northern Sichuan Province, China. The Jiuzhaigou Valley World National Park was the most affected area due to the epicentre being located in the scenic area of the park. Understanding the distribution characteristics of landslides triggered by earthquakes to help protect

Applying the Newmark Model in the Assessment of Earthquake Triggered Landslides During the 2017 Ms 7.0 Jiuzhaigou Earthquake, China

2020
The 8 August 2017 Jiuzhaigou, China, earthquake (Ms 7.0) occurred within Jiuzhaigou County, northern Aba Prefecture, Sichuan province, China. The earthquake generated 4834 coseismic landslides with individual areas >7.8 m2 over a 600 km2 region. Both the quantity of landslides and the areas that were affected by landslides are similar to those typical ...
