Optimised gravity anomaly fields from along-track multi-mission satellite altimeter over Malaysian seas Tập 33 Số 1 - 2022
Nornajihah Mohammad Yazid, Ami Hassan Md Din, Abdullah Hisam Omar, Nazirah Mohamad Abdullah, Muhammad Faiz Pa’suya, Mohammad Hanif Hamden, Noor Anim Zanariah Yahaya
AbstractMarine gravity anomalies are crucial parameters and elements for determining coastal and ocean geoid, tectonics and crustal structures, as well as offshore studies. This study aims to derive and develop a marine gravity anomaly model over Malaysian seas from multi-mission altimetry data. Universiti Teknologi Malaysia 2020 Mean Sea Surface Model is computed ...... hiện toàn bộ
Generic workflow of groundwater flow simulations in geologically complicated domains with millions of unstructured grids Tập 33 Số 1 - 2022
Tai-Sheng Liou, Sung-Yang Huang, Chao-Yan Lin, Ting-Wei Huang, Chuan-Wei Chung, Pei-Shan Hsieh, Cheng-Kuo Lin
AbstractNumerical groundwater flow simulation involves manual and tedious pre-processing and post-processing procedures. Hence, this study developed a systematic and efficient workflow to alleviate model buildup and data-processing burdens, allowing researchers to focus on the application aspects of simulation results. This highly automatic workflow allows research...... hiện toàn bộ
Deep learning-based earthquake catalog reveals the seismogenic structures of the 2022 MW 6.9 Chihshang earthquake sequence Tập 35 Số 1 - 2024
Wei‐Fang Sun, Sheng-Yan Pan, Chang-Jen Huang, Zhuo-Kang Guan, I-Chin Yen, Cheng-Seen Ho, Tsung-Chih Chi, Cheng-Yuan Ku, Bor‐Shouh Huang, Ching‐Chou Fu, Hao Kuo-Chen
AbstractOn 18 September 2022, the MW 6.9 Chihshang earthquake struck the south half of the Longitudinal Valley, Taiwan, and caused severe damage. A precise and rapid report for the distribution of aftershock sequence after a devastating earthquake provides key information for deciphering the seismogenic structure in the source region. The utili...... hiện toàn bộ
Developing innovative and cost-effective UAS-PPK module for generating high-accuracy digital surface model - 2023
Cheng-Hao Lu, Sheng-Ta Tsai, Ming‐Tien Wu, Di-Yi Lin
AbstractTraditional indirect georeferencing requires time-consuming and labor-intensive field surveys to obtain ground control points (GCPs), making it challenging to apply in high-risk areas with limited accessibility. This study proposes a novel and low-cost system for direct georeferencing using unmanned aerial system post-processing kinematics (UAS-PPK), which ...... hiện toàn bộ
Introduction to the special issue on the Hualien earthquake swarms - 2022
Ruey‐Juin Rau, Wen‐Tzong Liang
AbstractThe Hualien city is located near the pole of rotation induced by the along-strike transition from Ryukyu subduction to the collision between the Luzon arc and the Chinese continental margin in northeastern Taiwan (Rau et al., J Geophy Res 113: B09404, 2008). Such a tectonic regime creates varied seismogenic structures that are responsible for the ruptures o...... hiện toàn bộ
Effects of anthropogenic aerosols on the evolution of Indian summer monsoon - 2023
Kuan-Tzu Huang, Chung‐Hsiung Sui, Min‐Hui Lo, Yu-Yang Kuo, Chi-Jen Chang
AbstractThe NCAR Community Earth System Model is used to study the influences of anthropogenic aerosols on the Indian summer monsoon (ISM). We perform two sets of 30-year simulations subject to the prescribed perpetual SST annual cycle. One is triggered by the year 2000 climatology anthropogenic aerosol emissions data over the Indian Peninsula (referred to as AERO)...... hiện toàn bộ
Exploring changes in building strength using seismic wave deconvolution Tập 35 Số 1 - 2024
Yu‐Ting Chou, Chun Fu Liao, Strong Wen
AbstractIn order to avoid the casualties caused by damaged buildings during strong earthquakes, it’s important and essential to understand the seismic design specifications of buildings. The motion of a building depends on the interferometry of building and ground motion, the coupling between building and ground, and the mechanical properties of the building. We ap...... hiện toàn bộ
