Frequency‐Dependent Moment Tensors of Induced Microearthquakes [PDF]
, 2019 Analysis of 984 induced microearthquakes from The Geysers geothermal reservoir in California reveals that the retrieved moment tensors depend on the frequency band of the inverted waveforms. The observed dependence is more significant for the percentages

On the origin of exponential growth in induced earthquakes in Groningen [PDF]
, 2016 The Groningen gas field shows exponential growth in earthquakes event counts around a magnitude M1 with a doubling time of 6-9 years since 2001. This behavior is identified with dimensionless curvature in land subsidence, which has been evolving at a ...

Light Induced Training of 3D Printed Mechanical Metamaterials
Advanced Materials Technologies, EarlyView.A new 3D‐printable material that stiffens under UV light is integrated into the architecture of mechanical metamaterials to realize trainable systems. Local stiffening amplified by rational design enables closed‐loop systems with tunable properties guided by UV irradiation. The resulting structures gradually adapt shape or resistance, demonstrating how

In situ ambient vibration modal analysis of saguaro cacti (Carnegiea gigantea)
American Journal of Botany, EarlyView.Abstract Premise The structural and dynamic properties of columnar cacti are key inputs for stability analyses; however, no previous studies have been able to resolve these properties from full‐scale tests in situ. Methods I present an approach using non‐destructive ambient vibration data to measure the resonance properties (modal frequencies and mode ...

Importance of small earthquakes for stress transfers and earthquake triggering
, 2004 We estimate the relative importance of small and large earthquakes for static stress changes and for earthquake triggering, assuming that earthquakes are triggered by static stress changes and that earthquakes are located on a fractal network of ...

Interpreting intraplate tectonics for seismic hazard : a UK historical perspective [PDF]
, 2012 It is notoriously difficult to construct seismic source models for probabilistic seismic hazard assessment in intraplate areas on the basis of geological information, and many practitioners have given up the task in favour of purely seismicity-based ...
