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 ...

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 ...

An efficient hydraulic fracture geometry calibration workflow using microseismic data [PDF]
Microseismic technology has proven its efficiency to monitor hydraulic fracturing effectiveness. The objective of this study is to develop a novel method to calibrate and generate the hydraulic fracture cluster-based model of a multi-stage horizontal ...

Mine microseismic signal denoising method and application based on Adaboost_LSTM prediction
Microseismic early warning is of great significance for ensuring mine safety, where a good denoising and accurate P-wave arrival picking of a microseismic signal is fundamental to the reliability of microseismic monitoring. By observing a large amount of

Abstract We present evidence of a previously unrecognized east‐west‐trending normal fault, named the Parguera Fault, in southwest Puerto Rico. The fault is located at the northwestern edge of seismicity from the southwest Puerto Rico seismic sequence that began in 2019, near the coastal town of La Parguera.

High pressure fluid injection into geologic formations can trigger rock deformation and failure and lead to microseismic events. Injection induced seismicity has been proposed as a monitoring technique that can be used to constrain the description of ...

Evaluating Fragmentation Detection in Block Caves Using Synthetic Muon Tomography
ABSTRACT Muon tomography is a geophysical imaging technique with growing application across a range of geological and industrial settings. By observing the arrival of naturally occurring muons, it is possible to reconstruct subsurface density distributions in three dimensions.

PORTABLE WIDEBAND MICROSEISMIC DATA ACQUISITION SYSTEM [PDF]
Microseismic monitoring has gained importance ever since a correlation was established between earthquakes and intensive mining operations at various mine sites across the world. A microseismic network is in place at the Cory, Saskatchewan, mine site to

Automatic Classification of Microseismic Records in Underground Mining: A Deep Learning Approach
The identification of suspicious microseismic events is the first crucial step in processing microseismic data. In this paper, we present an automatic classification method based on a deep learning approach for classifying microseismic records in ...

Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...
