Understanding Location Styles


Both in Standard and and Pro versions you can apply a ‘style’ to any incoming location, and even change it completely.

Please note that NONE of these are retrospective and only apply forwards from a change. If you would like to have a retrospective application please leave a comment and I will see what I can do!

FE is Flinn-Engdahl and refers to that naming convention. SR is the seismic region and is the smae in both FE and GL, but the GL seismic regions may vary very slightly from their FE counterparts. GL is Gabbitas-Loring and is a naming system that seeks to further refine the areas defined in Flinn-Engdahl. Currently it is only available for the New Zealand region and all other regions return the same names as the Flinn-Engdahl counterparts. GAC stands for Geographical Area Code. SAC stands fro Sub Area Code. In FE the sub areas are the same as the geographical areas.

Because the FEGL module I created is installed with the program you have the ability to alter the location descriptions.

The various parameters, which you can set in the Config Database Settings section, are as follows:

Variable Code Description
As Is 0 Passes any text through without alteration except that New Zealand jobs return the GL geographic sub area names (see 4) and other blank text returns the FE geographic area name.(see 2)
As Is + Append SR 1 Adds the Seismic Region name CODE to the end in brackets, e.g. ’32Km N Of Rabaul. P.N.G (15)’. The NZ and ‘blank’ provisions are the same as (0).
FE Name Only 2 Irrespective of the incoming current location text the text is REPLACED with the FE geographic area name. e.g ’32Km N Of Rabaul. P.N.G’ would become ‘New Ireland Region. P.N.G.’
FE Name + Prefix FE GAC 3 This is (2) combined with a prefix of the geographic area CODE thus ’32Km N Of Rabaul. P.N.G’ would become ‘190 – New Ireland Region. P.N.G.’ Using this format for all providers enabled sorting on screen by location in a sensible manner.
GL Name Only 4 Identical to (3) above but the GL geographic sub area name is used instead. Since we have only defined sub area names for New Zealand so far, and FE sub area names are the same as area names this is a good setting for New Zealand and is in fact the default.
GL Name + Prefix GL GAC 5 This is (4) combined with a prefix of the geographic area CODE thus ‘West Chatham Rise’ would become ‘68901 – West Chatham Rise’ Using this format for all providers enabled sorting on screen by location in a sensible manner. Be aware however that the regions not defined would also return a 5 digit prefix thus ‘190 – New Ireland Region. P.N.G.’ in this version would be ‘19001 – New Ireland Region. P.N.G.’
As Is + Append FE GAC 6 Like (1) above but appends the sub area CODE to the end in brackets e.g. ’15Km WNW Of Rincon. Puerto Rico (90)’
As Is + Append GL GAC 7 Like (1) above but appends the sub area CODE to the end in brackets e.g. ’15Km WNW Of Rincon. Puerto Rico (9001)’
FE + Append FE GAC 8 A different version of (3) that REPLACES any text with the FE geographical name and appends the geographical CODE to the end in brackets rather than prefixing it e.g. ‘Santa Cruz Islands (184)’. It is important to note that this is applied to NZ areas as well. Use 9 if you want GL sub area names.
GL + Append GL GAC 9 A different version of (4) that REPLACES any text with the GL sub area name and appends the sub area CODE to the end in brackets rather than prefixing it e.g. ‘Santa Cruz Islands (18401)’.
Full FE 10 Uses the FE area name suffixed with the seismic region and sub area numbers e.g Nr Some Town (14/184-Santa Cruz Islands). If the incoming name matches the sub area name then it will return the sub area name just once e.g. Santa Cruz Islands (14/184)
Full GL 11 Uses the supplied name suffixed with the seismic region and area numbers e.g Nr Some Town (43/68901-West Chatham Rise). With GeoNet events, or where there is no incoming name, it will return the sub area name just once e.g. West Chatham Rise (43/68901). If the incoming name matches the sub area name then the same will apply.

None of these affect any ‘Felt’ or ‘Tsunami’ flags and thus a felt quake that may have caused a tsunami would be shown as below:

2013-04-23 23:14:42, -3.910, 152.126, 6.5, 16.2, 32Km N Of Rabaul. P.N.G (15) {F}{T}

or

2013-04-23 23:14:42, -3.910, 152.126, 6.5, 16.2, New Ireland Region. P.N.G. (15) {F}{T}

or one of the other variations.

You can play with these in the main program using the tools menu. Tools > FE Region Name Finder.

The settings permit you to have different styles for all four main providers – USGS, EMSC, GeoNet (New Zealand) and GeoScience (Australia) and the Pro versions add GFZ Potsdam to the mix. The is a general setting that will be applied to any other providers in the Pro versions.

Note: Currently styles are NOT applied to BBNET (Greece), Vedur (Iceland) or JMA (Japan)
