On 2016 November 13, an Mw 7.8 earthquake occurred in the northeast of the South Island of New Zealand near Kaikoura. The earthquake caused severe damages and great impacts on local nature and society. Referring to the tectonic environment and defined active faults, the field investigation and geodetic evidence reveal that at least 12 fault section...
Plain Language Summary
The relative motion between the Pacific and North American plates is largely focused on the dextral San Andreas fault system. A complex array of strike‐slip and normal faults, known as the Walker Lane and the Eastern California shear zone, accommodates about a quarter of this plate motion. The 2020 Monte Cristo Range earthqua...
The 2021 Mw 7.4 Maduo earthquake occurred in the north-central Bayan Har block, which has been the most seismically active block of the Tibetan Plateau during recent decades. The Maduo earthquake provides an opportunity to study the rupture kinematics and seismogenic environment associated with subsidiary faults inside the block. We investigate the...
The Pacific and Okhotsk plates are converging at a rate of about 9 cm/a, thereby forming the Japan Trench subduction zone. Two large earthquakes occurred in the offshore region of Fukushima on 13 February 2021 (Mw 7.1) and 16 March 2022 (Mw 7.3). The occurrences of the two earthquakes are close in space and time, thus constituting the Fukushima-Oki...
Seismic hazard assessment is significant for decreasing the risk of future earthquake disasters. Source rupture process model is a tool to understand the kinematically temporal and spatial history of source faulting. We have estimated the source rupture process of the 2016 Kumamoto, Japan earthquake from strong-motion records (Zheng et al., 2017, C...
In this study, we used the curved-grid-based finite-difference method to investigate the effect of local mountain topography on strong ground motion by earthquakes. The ground motions were simulated with different topographic irregularities in a three-dimensional homogeneous half-space. The topographic effect was analyzed in two aspects: one is the...
On 15 April, 2016 (UTC) the great earthquake with magnitude Mw7.1 occurred in Kumamoto prefecture, Japan. The strong shocking of the earthquake caused grave disasters and severe damages. The focal mechanism solution released by F-net of NIED of Japan indicates that the hypocenter is at 130.7630°E, 32.7545°N with a depth of 12.45 km. The nodal plane...
