NEIS is now locating the New Zealand earthquake as follows:

A magnitude 6.8 earthquake OFF THE E. COAST OF N. ISL, N.Z. has occurred at:
36.99S 179.02E Depth 33km Sun Oct 21 00:29:23 2001 UTC

This is likely to change in the next several days, however. Compare this
with the notice in the far-field Guam forecast:

New Zealand - North Island 37S 177E
Earthquakes of Mw>=6.5 have occurred within 2 weeks in New
Zealand after each earthquake in Guam since 1930 (with the
one exception of 1975). The probability of such an earthquake
in the next week to 10 days is considered very high. Local
personnel should be on watch, especially on North Island.
