The focal mechanism for this earthquake in Hawaii,          
which occurred approximately six minutes after the          
MW=6.7 mainshock, differs substantially from that           
of the mainshock, which had a near-horizontal axis          
of maximum extension (T axis). The CMT solution             
below was determined in a joint, two-source inversion       
for the focal parameters of both the 2006 10/15 17:07       
mainshock and this (2006 10/15 17:14) aftershock.           
                                                            
                                                            
Here is the solution for the recent event.
