...Chung‐Han Chan; Kuo‐Fong Ma; Ya‐Ting Lee; Yu‐Ju Wang ABSTRACT We examined the performance of Taiwan earthquake model (TEM) PSHA2015. We retrospectively forecasted the seismic activities of the 2018 Hualien, Taiwan, sequence and proposed recommendations for the next generation of seismic hazard...

...‐motion dataset of the Hualien mainshock was provided by the Central Weather Bureau (CWB), Taiwan (see Data and Resources ). Pulse‐like ground motions were observed at all stations within a distance of 4 km from the Milun and Linding faults around Hualien city ( Ji et al. , 2019 ; Kuo et al. , 2019...

... issued by the Central Weather Bureau and then broadcast whatever alert is received earliest. Shortly after the establishment of the NEEWS, the M L 6.3 Hualien earthquake, which had a maximum measured peak ground acceleration (PGA) of 515.17 Gal, struck Taiwan on 18 April 2019. During the earthquake...

... of this strong motion, especially in relation to building damage. Exactly 2 yrs before the 6 February 2018 Hualien earthquake, the 6 February 2016 M w  6.4 Meinong earthquake occurred in southwestern Taiwan. This earthquake also generated large pulse‐like velocity motions that were responsible for much...

... in eastern Taiwan at the leading edge of a modern arc–continent collision. Fatalities and damages were concentrated near the Milun fault and extended south to the northern Longitudinal Valley fault. Although the Hualien area has one of the highest rates of seismicity in Taiwan, the geologic structures...

...Chun‐Hsiang Kuo; Jyun‐Yan Huang; Che‐Min Lin; Ting‐Yu Hsu; Shu‐Hsien Chao; Kuo‐Liang Wen ABSTRACT The maximum observed peak ground acceleration (PGA) and peak ground velocity (PGV) at various stations during the 2018 Hualien, Taiwan earthquake were 594 Gal and 146 cm / s , respectively. Pulse‐like...

...Yih‐Min Wu; Himanshu Mittal; Ting‐Chung Huang; Benjamin M. Yang; Jyh‐Cherng Jan; Sean Kuanhsiang Chen ABSTRACT On 6 February 2018, an M w 6.4 earthquake struck near the city of Hualien, in eastern Taiwan with a focal depth of 10.4 km. The earthquake caused strong shaking and severe damage to many...

... days before and 30 days after the 2018 M w 6.4 Hualien earthquake, which occurred near the Milun fault (MF) in eastern Taiwan. By applying the matched‐filter technique to continuous waveform data, we identified approximately two times more earthquakes than listed in the standard Central Weather Bureau...

...Hao Kuo‐Chen; Zhuo‐Kang Guan; Wei‐Fang Sun; Pei‐Yu Jhong; Dennis Brown ABSTRACT The February 2018 M w 6.4 earthquake in eastern Taiwan caused extensive damage in Hualien City. Although damaging earthquakes are common in this region, there are relatively few permanent seismic stations deployed. Two...

...Shiann‐Jong Lee; Tzu‐Chi Lin; Ting‐Yu Liu; Tong‐Pong Wong ABSTRACT A fault‐to‐fault jumping rupture was found during the 2018 M w 6.4 Hualien earthquake that occurred in eastern Taiwan. Joint source inversion results indicated that the initial rupture started from a north–south (N‐S)–striking fault...

...Xiongwei Tang; Rumeng Guo; Luning Li; Ye Xu; Jianqiao Xu; Yong Zheng; Heping Sun Abstract Since 2000, eastern Taiwan has experienced 38 M w ≥ 5.5 earthquakes, leaving three seismic gaps along the Longitudinal Valley fault (LVF). In April 2024, the M w 7.3 Hualien earthquake occurred near the LVF...

... expected displacement on a fault and in its vicinity. To construct PFDHA, any new observed surface ruptures can be included. In 2018, an M w 6.4 earthquake hit the city of Hualien, Taiwan, and caused surface ruptures along the Milun fault. Immediately after the earthquake, field investigations were carried...

..., which broke during the 2018 Hualien earthquake ( M w 6.4) in eastern Taiwan. Correlation of pre‐ and postearthquake stereo Pléiades images reveals detailed 3D surface displacements along the 8‐km‐long Milun fault, with maximum ∼ 1 m left‐lateral offsets across the fault. Along the northern section...

... ). Therefore, P alert devices can be connected in order to build a regional EEWS ( Kanamori, 2005 ; Wu and Kanamori, 2005b ). An experimental system was successfully tested in Hualien, Taiwan ( Wu and Lin, 2013 ). Because of this successful experiment for both onsite and regional EEWS purposes, we began...

...Yih-Min Wu; Himanshu Mittal; Da-Yi Chen; Ting-Yu Hsu; Pei-Yang Lin Abstract The earthquake early warning (EEW) system in Taiwan is the outcome of rigorous research work carried out at various levels after the occurrence of the 1986 Hualien earthquake that caused destruction. After more than 25...

... of subsurface soil structure caused by the faulting due to the tectonic structure. The large pulse during the mainshock was generated by source effects, rather than subsurface amplification. The 6 February 2018 M w  6.4 Hualien, Taiwan, earthquake (at 23:50:43 local time) showed a very...
