Survey Setup

The Grid Based Analysis application can be used to evaluate the spatial distribution of various seismic parameters. There are a range of source parameter options available, and they can give indications to the rock mass behaviour. Some parameters can be considered as a proxy (stand-in) for rock mass stress, while other parameters can be a proxy for the amount of deformation. There are also parameters available that are associated with the rock mass mechanism or event type.

Evaluating the spatial distribution of various seismic parameters.

Overview

For a few months now, a new tool has appeared in the General Analysis app; the hanging wall (HW) and footwall (FW) filter. The HW-FW filter allows you to filter your events based on where they are in relation to ticked survey/s. If more than one survey or plane is used for the HW-FW filter, they need to be somewhat parallel in order to make sense.

Analysing seismicity around large events

Mine Geometry Model Minode Generator is a new utility app which enables you to generate your own new minodes from a mine geometry model. If you're not sure what minodes are or why you would want to generate them, see What are minodes? If you're not sure what mine geometry models are, see Mine Geometry Models Application.

Stope, cave and development geometry is a fundamental aspect of most geotechnical analysis. Mine geometry also varies over time and capturing these changes is critical in any back analysis or numerical modelling that investigates stability or monitoring parameters over time. This is a utility app to create models of mine geometry that can be exported to facilitate a wide range of applications such as:

Where is the cumulative energy line on the Omori chart?

Why can't I see this event in mXrap?

You know that energy and moment are parameters to describe seismic events. But what exactly is their physical meaning for a seismic event source and how are they calculated?

Overview

Seismic Activity Rate Monitor

There are multiple features to analyse the short-term response to different triggers (events or blasts) in time and space. In later versions, this app will replace all of the tools in the previous 'Omori Analysis Tools' app but version 1 currently only replaces the old 'response to blasting' window. There are two main aspects of the app, the simple response viewer and trigger assessment windows.

The strong ground motion (SGM) relationship is used to calculate the peak particle velocity (PPV) generated by a seismic event. You may also hear this referred to as a ground motion prediction equation (GMPE), but only the maximum velocity is estimated, i.e. the strong ground motion, rather than the full, complex wave motion.

Time charts plot various hazard parameters over time, or, by time of day:

A few new features have been added to the Hazard Assessment application, aiming to improve usability, understanding and investigation. The first addition is a chart in the hazard setup window to indicate the current date range settings. Usually the date range for calculating b-value will be a lot longer than for calculating event rate. Hopefully the chart will be a handy visual aid to help you keep your bearings when setting the hazard analysis periods.
