... 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...

Chuang; Chih‐Heng Lu; Yi‐Chun Hsu; Hsin Tung; Jiun‐Yee Yen; Chung‐Pai Chang ABSTRACT We use high‐resolution Pléiades optical satellite imagery to study the distribution and magnitude of fault slip along the Milun fault surface rupture...

... dipping to the west and propagated to the south with a high rupture speed. The rupture then jumped to the shallower east‐dipping Milun fault. Slip on the Milun fault was slow and continued for more than 10 s, which produced the largest asperity near the city of Hualien. The rupture jumped again...

... 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...

... velocities were observed at all stations within a distance of 4 km from the Milun fault. The horizontal spectral accelerations of the pulse‐like records indicated two obvious amplifications at periods of roughly 1 and 2 s. Natural frequencies of 0.8–1.5 Hz were observed in the region near the Milun fault...

... of the Milun fault, which resulted in the collapse of five buildings. To investigate the shallow subsurface soil structure and evaluate possible effects on the ground motion and building damage, we performed microtremor measurements in the Hualien basin. Based on the velocity structure jointly inverted from...

... (RSQSim) to simulate the eastern Taiwan fault system, integrating fault geometry from the multidisciplinary Taiwan Earthquake Model. We applied long‐term simulations spanning 400,000 yr to conduct earthquake sequences and recurrence intervals on five distinct faults in eastern Taiwan: Milun fault...

...Figure 4. Rupture probability for (a) the Milun fault and (b) the Longitudinal Valley fault as a function of time elapsed since last event based on the Brownian passage time (BPT) model (blue lines) and Poisson distribution (green lines). The rupture recurrence intervals of these faults are 67...

... movement. The results indicate that the Milun fault could have experienced a left‐lateral movement. Ground displacements measured by continuous Global Positioning System (GPS) stations and campaign GPS stations are also presented. The results from the proposed method are consistent with that obtained via...

... toward failure. Moreover, the conjugate LVF and the Milun fault are activated, and some aftershocks are promoted here. Finally, we note that the Coulomb stress changes from historical earthquakes and the 2024 Hualien earthquake exert positive stress on the seismic gaps in the northern LVF, potentially...

.... The modified baseline correction procedure corrects all 126 accelerograms for three directions of the 42 strong‐motion stations. The recovered ground displacements are consistent with geodetic measurements, demonstrating complex surface deformations in the close vicinity of the Milun fault. 3 July 2023...

... 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...
