%        EQ Function that defines position (lon,lat,depth) for event
%                     Nathanael Wong Zhixin, Feng Lujia
%
% This function calls subfunctions based on prior information to define the
% position (lon,lat,depth) of the fault events.
%
% INPUT:
% -- EQtype : model type input
% -- EQdim  : event rupture dimensions information
% -- EQgeom : event geometry information
%
% OUTPUT:
% -- EQpos  : structure containing the xy position and depths of the event
%             .xy - lon,lat information
%             .z  - depth information
%
% FORMAT OF CALL: EQ_create_pos (model type,dimensions,geometry)
% 
% OVERVIEW:
% 1) This calls as input the modelling, dimensions and geometry
%    information, to extract the model fault type, slab information, as
%    well as the width and dip information.
%
% 2) The function will then call subfunctions to determine the (lon,lat)
%    and depth information
%
% 3) The function then exports the information into the parent
%    script/function.

%    -- For fault types 1 & 3, EQlon1 and EQlat1 serve as the coordinates
%       of the epicenter
%    -- For fault types 2 & 4, the function will call for an input of the
%       epicenter coordinates in order to find the depth of the fault
