Each segment is defined by two to maximum of five nodes

Delineate segment-strike: Click the map or type Lat/Lon values to define segment-nodes

Enter values for top, width, dip, dip-direction, and mechanisms for the segment

Register segment data: Segment will be added to the text-box

Repeat the above steps to define different segments for the fault

Use "Copy Data to Clipboard" button to copy the compact segments data to clipboard

Save segments data to a text file on your computer for future use

Note

• A segment dip-direction is relative to its strike, see the page-document for more info
• The coordinates of a clicked point on the map will be displayed in the Lat/Lon input boxes
• The map can be cleared/centered at the user defined Lat/Lon coordinates
• It is user's responsibility to define segments with reasonable strikes without zigzags or crossing coordinates

An example of a two-segmented fault data (compact format)

{1; 12; 1; 45; Right; Reverse/Thrust; 3; 34.6762; -117.4477; 34.2686; -116.9753; 33.7130; -116.5688;}:: {2; 12; 1; 45; Left; Strike-Slip; 3; 34.8362; -117.0168; 34.1844; -116.2807; 33.3716; -116.1929;}

The data represent the two sets of the following information:
{ID; Width; Top; Dip; Dip-Direction; Mechanism; Nodes; Lat; Lon; ...}

Note:

• Coordinates are comma delimited: [latitude, longitude, ....]
• Segment-data can be defined on a single line as long as the values follow the given format
• Dip-Direction is defined as Right or Left, reflecting the dipping-direction of the rupture plane relative to a vector drawn from the first node toward the last node
• Rupture-Mechanism is identified as Strike-Slip, Reverse/Thrust, or Normal
