neic-glass3 v1.4.1

neic-glass3

• Made changes so that exotic phases can be associated with the proper hypo and not create false events.
  • Added the capability to configure a travel time phase such that it can be associated with a hypo, but not affect the hypo's location.
  • Added the capability to configure a travel time phase such that it can be associated, will not be reported or output as part of a detection message.
  • The association range for phases configured to not affect the hypo's location is much larger (configurable) if the hypo has enough phases at teleseismic distances.
  • Added the following travel time phase files: PKKPab, PKKPbc, PKKPdf, PKiKP, P'P'ab, P'P'bc, P'P'df.
• Removed the travel time Range command, as it was unused by the code.
• Fixed a travel time configuration bug that caused the Assoc command for a Phase to always affect the next phase in the list instead of the Phase it was supposed to.
• Added a new publication command, ImmediatePublicationThreshold. This command will cause neic-glass3 to publish a hypo 10 seconds after the hypo's bayes value exceeds this threshold.

neic-glass3 v1.3.0

neic-glass3

• Replaced the existing neic-glass3 travel time package (libraries, files, and models) with a new package based on the NEIC's ttimes package neic-traveltime to better match other NEIC algorithms and support additional velocity models. Note that the travel time lookup file format changed and requires configurations to be updated with the new files.

• Modified core algorithm to use two pick (instead of two station) nucleation. Previously nucleation was tied to the number of stations, so only one P or S pick could be used. This hampered the sensitivity of the algorithm. The result of this change will increase the sensitivity of two-phase nucleation for a given configuration as compared to previous versions.

• Added support for a simple input pick format: ID NET STA CHAN LOC TIME PHASE This format is mapped to the .txt extension

neic-glass3 v1.1.1

This release fixes a bug where neic-glass3 was not correctly issuing retraction messages as described in PR #62.

neic-glass3 v1.1.0

This version of neic-glass3 contains updates to ensure compatibility with the latest version of earthquake-detection-formats.

neic-glass3 v1.0.7

This introduces features where nucleation and association can rely on classification data on distance and azimuth supplied with the pick. These are fully configurable. Also added a function to correctly calculate the difference between two angles.

neic-glass3 v1.0.6

The iterations and search distance for the locator has been increased in response to marginal events not always being detected. The changes should stabilize the output of neic-glass3.

neic-glass3 v1.0.5

neic-glass3

Fixed a startup crash bug in glass-broker-app when attempting to configure a topic.

neic-glass3 v1.0.4

neic-glass3

Fixed a bug in writing updated station lists to disk due to an incorrect back conversion of station elevation to meters.

Fixed a bug where glass-broker-app would only write heartbeats to the first configured topic rather than all configured topics.

Updated neic-glass3 to support recent changes in earthquake-detection-formats

Added support for rejecting picks classified as "noise" above a configurable probability threshold.

Added support for utilizing classified pick phase identification in nucleation and association above a configurable probability threshold.

neic-glass3 v1.0.2

neic-glass3

Corrected an issue where glass-broker-app would occasionally unexpectedly terminate due to a timeout of the thread that requests station information, due to resource contention.

The glass-app application segmentation fault on shutdown known bug has been fixed.

Updates glass-broker-app to support heartbeat functionality recently added to the hazdev-broker library.

neic-glass3 v1.0.1

neic-glass3

Corrected an issue where certain events were not triggering due to additional nucleation restrictions added to speed up computations. These restrictions were modified to improve detection performance at a slight cost in computational speed.

Known Bugs

The glass-app application will segmentation fault on shutdown with the following message ‘terminate called without an active exception’. This behavior is harmless since it occurs after all data has processed and the program is exiting, and will be fixed in a later release
