Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Higher‐mode effects can significantly amplify seismic demands in high‐rise buildings, causing unintended damage over the building height. Engineered mechanisms are introduced at the base of these structures to mitigate higher‐mode effects. Existing continuum formulations for base‐flexible buildings commonly idealize the superstructure as a ...

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Monitoring of Anthropogenic Seismicity in Italy: State of the Art
, 2018 In Italy the discussion about anthropogenic seismicity started after the deadly M6 Emilia earthquakes in 2012. Occurring these events in an area of gas and oil production, the question raised, whether exploitation induced crustal stress variations that ...

SeismicaThe rate of felt earthquakes in Kansas increased dramatically in 2014, where most seismicity initially occurred in southern Kansas, and was attributed to large-volume wastewater disposal (WD) near the Oklahoma-Kansas border.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Earthquakes often occur in clusters (foreshocks, mainshocks, and aftershocks) and can lead to cumulative structural damage. Many studies have extended traditional performance‐based earthquake engineering (PBEE) to account for damage accumulation in multiple mainshock‐aftershock (MS‐AS) sequences using Markov chain processes and state‐dependent

Reduced Injection Rates and Shallower Depths Mitigated Induced Seismicity in Oklahoma
The Seismic RecordThe proximity of wastewater disposal to the Precambrian basement is a critical factor influencing induced earthquake rates in the Central United States, but the impact of reducing injection depths has not been widely demonstrated.

Decomposing significant factors of Coulomb stress and its components in injection-induced seismicity
Journal of Rock Mechanics and Geotechnical EngineeringInjection-induced seismicity has been a focus of industry for decades as it poses great challenges to the associated risk mitigation and hazard assessment.

, 2020 In many cases, fluid injections into the subsurface have been recognised to cause seismic activity. Understanding the driving physical processes of these man-made earthquakes and their occurrence in time and space is of significant scientific and public ...

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Geophysical Research Letters, 2016 We explore the role of earthquake interactions during an injection‐induced seismic sequence. We propose a model, which considers both a transient pressure and static stress redistribution due to event interactions as triggering mechanisms. By calibrating
