Filter volumes library changes

Matthew Heinsen Egan
Senior Software Engineer

We have recently updated the JavaScript library mxjs/base/algorithms/filter_volumeset.js to be more efficient. If you are using this library and call the flag_members() method of volume sets directly, then you will need to update your code slightly. If you don't call flag_members() directly then you'll automatically get the efficiency updates when you upgrade without needing to do anything, and you can stop reading now :)

mXrap Version 6.0.0 - Release notes and Changelogs

mXrap Team
Developers

Highlights

We're pleased to announce the release of mXrap version 6, bringing with it a range of enhancements to elevate your mXrap experience. This major update includes improvements to the user interface, as well as enhancements to speed when loading the root folder and applications. Additionally, we've upgraded the 3D rendering and navigation capabilities in the 3D views.

Updates to Short-term Response Analysis

There have been a number of recent updates to the Short-term Response Analysis app. These include:

  • Chart for determining re-entry using different parameters: This chart gives you values for a particular parameter over time (based on a user-defined time window size and step). A threshold value for that parameter can be set, allowing you to see when the seismic data drops below that threshold. The parameter investigated can currently be set to energy, event count, hazard, background ratio and activity rate probability. For more information about these parameters, see Tierney et al. 2019.

Marker Style Updates

The upgrade to mXrap version 5.16 introduced a variety of changes and improvements to marker styles. The changes can be separated into general updates which are relevant to all users and developer updates which are relevant to app developers who create and customise marker styles.

Updates to Hazard Assessment app

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.

Moment tensors in General Analysis app

Moment tensors have been added to the General Analysis application in the recent update. Beach balls and principal axes can be viewed in the General Analysis 3D view. There is also a separate Moment Tensor window with a number of stereonets and mechanism charts. Two new training videos have been uploaded to the General Analysis (3D View) page that walkthrough the new tools.
