Mine Seismicity

The Mine Seismicity module provides tools for the analysis and interpretation of seismic data and management of seismic hazard.

Key Apps

General Analysis

Core exploratory tool with 3D views, charts, tables, filters, selections, VTM, event density isosurfaces, and moment tensor visualisation.

Large Event Analysis

Focused on large events, including PPV ground motion assessment, precursory seismicity review, and plane-based analysis.

Grid-based Analysis

Grid-based seismic hazard assessment using seismic data for spatial hazard mapping and analysis.

Hazard Assessment

Probabilistic seismic hazard evaluation based on grid and spatial methods

Fault-Based Analysis

Tools for importing and evaluating various formats of extensometer and in situ stress data.

Short-term Response Analysis

Supports short-term seismic response evaluation to select large events and blast triggers.

Omori Analysis

Dedicated to analysing blast-related seismicity using Modified Omori Law fitting, cumulative event distributions, and related charts for quantifying decay patterns.

Seismic Monitoring

Real-time/basic monitoring apps (including Standard and Enhanced versions, plus setup tools) for event alerts, activity rates, and exclusion zones.

System Design

Assists with seismic monitoring network planning, sensor placement optimisation, coverage evaluation, and system sensitivity assessment.

Seismic Event Quality

Dedicated checks and validation of seismic event data quality.

Plane Fitting

Tools for fitting planes to seismic event clusters.

These apps integrate with mine geometry and other mXrap utilities for real-time data visualisation and analysis.
