Deep Underground Science and Engineering, EarlyView.This study reveals the failure evolution characteristics of deep cross‐fault roadway surrounding rock under excavation support and periodic weighting. Periodic weighting readily induces fault activation, with the spatial distribution of failed rock masses being controlled by the fault strike and dip.

Ecography, EarlyView.Latitudinal diversity gradients (LDGs) arise from the interplay of historical, ecological, and evolutionary processes, yet these drivers may differ across landforms. Mountains, with steep elevational and climatic gradients, often sustain distinct diversity dynamics compared with adjacent lowlands, where vertical climatic gradients are weak and human ...

The measurement and analysis of similarity degree on data from two types of seismic recorders
AIP AdvancesSeismic instruments are widely used in projects related to geophysical prospecting. Quality data from seismic recorders help to determine subterranean structures with high precision. This paper first introduces a field experiment carried out by deploying

Full Wave-equation Based Passive Seismic Imaging and Multispectral Seismic Geometric Attributes [PDF]
, 2020 Both passive (e.g., microseismic) and active seismic methods are used for the hydrocarbon exploration. For example, microseismic data analysis provides helpful information in not only mapping hydraulic fracture initiation, but also reservoir monitoring ...

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

An earthquake response spectrum method for linear light secondary substructures
, 2007 YesEarthquake response spectrum is the most popular tool in the seismic analysis and design of structures. In the case of combined primary-secondary (P-S) systems, the response of the supporting P substructure is generally evaluated without considering ...

Characterizing Seismic Scattering in 3D Heterogeneous Earth by a Single Parameter
, 2020 We derive a theoretical parameter for three seismic scattering regimes where seismic wavelengths are either much shorter, similar, or much longer than the correlation length of small-scale Earth heterogeneities.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

Correlations between Damage Indices and Seismic Parameters for Near-Field Earthquake Records
Civil Engineering Dimension, 2014 Damage assessments of concrete structures are essential to determine their seismic performances under earthquake events. In this paper, six three bays two dimensional concrete frames, five to ten story high, were analyzed under 30 near-field earthquake ...
