NEW SEISMIC SOURCE ZONE MODEL FOR PORTUGAL AND AZORES [PDF]
, 2010 The development of seismogenic source models is one of the first steps in seismic hazard assessment. In seismic hazard terminology, seismic source zones (SSZ) are polygons (or volumes) that delineate areas with homogeneous characteristics of seismicity ...

Earthquake and Tsunami NaTech Risk Assessment for Oil Storage Facilities
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Interaction of natural and technological hazards (NaTech) events, such as tsunamis and earthquakes, can affect industrial facilities such as those featuring anchored atmospheric storage tanks. Consequences of natural events on this kind of installation may include the release of hazardous substances, which in turn can lead to industrial ...

Anomalous Seismic Activity and Earthquake Prediction
Journal of Physics of the Earth, 1977 The earthquake off the Izu Peninsula, on May 9, 1974 (M=6.9) was preceded by an anomalous seismic activity which started about 10 years and 4 months before, in July 1963 and can be distinguished from the ordinary seismic activity in the region. This earthquake was not, however, preceded by immediate foreshocks. At the same time there seems to have been

Finite Element Modelling of Rocking and Hybrid Precast Walls under Seismic Loading
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT In recent years, self‐centring systems have received considerable research interest in the seismic design of precast concrete structures for their ability to limit damage and satisfy resilience requirements. Rocking and hybrid structural walls, characterised by the formation of a single gap at the wall–foundation interface, mitigate damage by ...

基于深度学习地震检测的2022年门源MS6.9地震序列活动性分析
Dizhen xuebao本研究收集了2022年1月8日青海省门源MS6.9地震震中200 km范围内，主震前129天至震后235天的高密度观测台网资料，利用基于深度学习模型的微震检测定位对此次地震的地震活动性进一步进行解剖。使用深度学习拾取模型DiTingPicker从连续原始地震波形数据中自动检测事件并拾取震相，然后利用REAL模型进行震相关联，再利用Hypoinverse和HypoDD程序分别进行绝对定位和相对定位，最终得到2021年9月1日到2022年8月31日的地震目录3 637条 ...

Energy Science &Engineering, EarlyView.With the advancement of coal mining technology driving the development of working faces toward increased mining heights and extended lengths, the enlargement of face dimensions has led to expanded overlying strata failure zones and intensified ground pressure manifestations. Consequently, traditional methods for determining hydraulic support resistance
