Table 1. Comparisons between
event locations as reported in local bulletins and those obtained using
our automatic location scheme - differences are mostly small. The few exceptions
in this regard are events located outside or on the periphery of the German
(ca 8 stations used) and Norwegian (ca 6 stations used) network areas where
the epicenter resolution is relatively poor for any location method. Ca
20 stations used from Italian network area.
Table 2. Listing of the weak
events (Germany) detected with our approach. Note, Events 4 &
5 interfere with each other - analyst unable
to analyze properly these two events.
Remark: such a high accuracy of the
method is caused, in fact, by the use of a group
velocity rather than a phase one - the
latter is much more dependent on a local crust structure. See, e.g.
"Energetic Envelope Transform"
