REVISED Quick CMT: 

04/20/2002, 10:50:44, NEW YORK, Mw=5.0

The following is a REVISED solution for the April 20, 2002,
event in New York. This CMT solution was determined by
analysis of long-period body waves (45-150 s) and
intermediate-period surface waves (40-100 s or 50-200 s).
A preliminary very-broad-band analysis of teleseismic
P waveforms gives a depth for this event of 10.4 km.

Here is the solution for the recent event.

April 20, 2002, NEW YORK, Mw=5.0
