TCS AH provides access to software dealing with specified scientific problems, designed in the area of anthropogenic hazards. All of these services consist of software packages and visualization services, both applied to selected data subsets that a user has pre-defined and uploaded to the personal workspace. The users have therefore the possibility to proceed to either episode-oriented research (application of various methodologies focusing on a particular episode), or method-oriented research (perform a certain methodology at several datasets in order to compare results with each other and test the efficiency of selected approaches).

The following applications are already implemented:

Source Localization
This application implements TRMLOC localization/relocalization software which performs efficiently the inversion of seismic (acoustic) first arrival time onsets for hypocenter location using the probabilistic inverse theory approach

Moment Tensor Inversion
This application implements a command line application, focimt for estimating the moment tensor, which is a standard for description of earthquake kinematic source processes in the whole range of magnitudes.

Earthquake Spectra
This application determines seismic source parameters based on spectral analysis of the P and S waves. Two independent spectral parameters, i.e. low frequency spectral level and corner frequency, are estimated with  Snoke’s fitting algorithm. Assuming Brune's source model and spectral parameters

Completeness Magnitude Estimation
The completeness magnitude of a given catalog, Mc, defined as the lowest magnitude at which all seismic events in a selected space-time volume are recorded by a network, is calculated by this service.

Source Size Distribution Functions | Stationary Seismic Hazard
This application implements several functions for estimating the probability density function and cumulative distribution function of magnitude.

Time-Dependent Seismic Hazard (in mining front surroundings)
This application comprises functions which are dedicated to episodes associated with mining induced seismicity. Its purpose is to evaluate seismic hazard parameters in connection with the evolution of mining operations and therefore to detect a causative relationship between seismic events and front advance.

Time-Dependent Seismic Hazard (in a selected area)
This application is a generalization of time-dependent seismic hazard, which can be performed for all episodes. Its purpose is to evaluate the temporal evolution of the seismic hazard parameters and therefore to detect a causative relationship between seismic events and production/technology activity

Stress Inversion
This application implements the software package MSATSI which allows performing stress inversion using earthquake focal mechanisms. The purpose of this service is to determine the stress axes orientation and relative stress magnitude by inverting earthquake focal mechanisms.

Visualization include several generic tools implemented in the platform. The tools can be used to illustrate, e.g. the evolution of seismic activity together with the production/technological processes related to each episode. Various plotting options are provided, allowing the users to identify potential patterns and links between seismicity-technology. Depending on the inducing technology of the episode and the available data, the following additional visualization tools are offered: (i) visualization of mining front advance; (ii) seismic activity with water level, water volume, injection rate or wellhead pressure; (iii) injection rate and wellhead pressure histograms; (iv) focal mechanisms demonstration; (v) integrated episode data and 3D visualization.
