The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

Assessment of seismic disaster risk in the Dingri earthquake based on fault-induced ground motion effects

Geomatics, Natural Hazards & Risk
Accurate and efficient seismic disaster risk assessment is essential for disaster prevention and emergency response, yet current approaches often inadequately integrate multiple drivers and capture spatial heterogeneity in active tectonic zones.

Assessing infrequent large earthquakes using geomorphology and geodesy in the Malawi Rift [PDF]

, 2015
In regions with large, mature fault systems, a characteristic earthquake model may be more appropriate for modelling earthquake occurrence than extrapolating from a short history of small, instrumentally observed earthquakes using the Gutenberg–Richter ...

An optimizing microseismic method for rock burst early warning based on mining production process

Deep Underground Science and Engineering, EarlyView.
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Analysis of the synchronous rise of water level in the Tangshan fault zone

Scientific Reports
Since 2019, a synchronous and abnormal upward trend in water levels has been observed in the Tangshan and Majiagou observation wells, located within the Tangshan fault zone, coinciding with three earthquakes of magnitude 4.0 or higher in the Tangshan ...

Velocity structure tomography analysis in southern Hebei Province

地震科学进展
The destruction of cratons is one of the key research objects of geophysicists. According to China Earthquake Networks Center, small and medium-sized earthquakes have occurred more frequently in southern Hebei in recent years than before.

Seismic Hazard and Public Safety [PDF]

Eos, Transactions American Geophysical Union, 2013
The recent destructive earthquakes in Wenchuan (China), L'Aquila (Italy), Port‐au‐Prince (Haiti), Christchurch (New Zealand), and Tohoku (Japan) have reignited the discussion over seismic safety. Several scientists [e.g., Stein et al., 2012; Wyss et al., 2012] have questioned the reliability of some seismic hazard maps based on the probabilistic ...

Landsliding and sediment dynamics following the 2008 Wenchuan Earthquake in the Beichuan area of China [PDF]

, 2011
Extensive and widespread landsliding is a common feature in a post-earthquake mountainous environment. The intense seismic shaking of an earthquake leaves the ground destabilised and thus very susceptible to slope failure.
