Volatile Conduits Beneath Vulcano Island (Italy) Revealed by High‐Resolution Nodal Local Earthquake Tomography During Volcanic Unrest

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Understanding shallow magmatic and hydrothermal systems at active volcanoes is essential for interpreting unrest and forecasting eruptions. We present the first high‐resolution three‐dimensional Vp $Vp$, Vs $Vs$, and Vp/Vs $Vp/Vs$ models of Vulcano Island, Aeolian Islands, Italy, derived from a dense nodal seismic network.

Simulator‐Based Bayesian Inference of Enhanced Geothermal Reservoir Properties

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Inversions of dynamic multi‐scale multi‐physics subsurface system properties rely on the effective sampling of high‐dimensional parameter spaces and are thus notoriously difficult to perform. The associated models are defined by complex nonlinear relationships with potentially stochastic components, which lead to analytically intractable ...

Solution of Microseismic Monitoring Non-Linear Location Equations Based Matlab

, 2011
Microseismic will produce when rock mass break. The occurrence of microseismic monitoring has close relationship to the energy release and crack's evolution in the rock mass. Therefore the microseismic monitoring can be used to predict the future rupture

Application of microseismic monitoring in the optimization of control strategy for roofs composed of composite hard sandstone masses

Meitian dizhi yu kantan
Objective With a gradual increase in the coal mining depth in China, the movement of overlying thick and hard rock layers exerts increasingly complex impacts on the mine pressure. Methods In the Ordos area, the overburden of the mining face of most mines

Comparison of Surface and Downhole Microseismic Acquisition [PDF]

, 2017
The most common microseismic monitoring methods used in the industry today are by the use of surface arrays and downhole arrays. In surface acquisition, sensors are deployed on the surface in large two-dimensional arrays, allowing this method to provide

3D Subduction Interface Model for the Hikurangi Margin, New Zealand: Implications for Slow Slip Events

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions in slow slip events (SSEs) that correlate with subduction interface ...

Subsurface Fluid Monitoring by Multi-Purposing Microseismic Sensor Arrays

, 2023
International audienceIn this paper we demonstrate how microseismic networks have been multi-purposed to identify variations in fluid saturation in the context of CO2 sequestration and underground gas storage. In traditional microseismic monitoring, only

Probability and Recurrence of Maximum Magnitude Based on Stochastic Modeling of Internal Fault Geometry

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The recognition that relay zones along faults can act as barriers to earthquake propagation implies that rupture size may not be random and earthquakes are constrained by fault geometry. Resolution and observational biases can, however, complicate the integration of actual fault zone geometries into deterministic modeling strategies, thereby ...

Effective VTI anisotropy for consistent monitoring of microseismic events

, 2011
The monitoring of induced or triggered microseismic events increasingly is being used to inform the efficient production of unconventional reservoirs. A key aspect of economic production in these low-permeability rocks is hydraulic fracture stimulation,
