Hawaii 'cautious' as earthquake-triggered tsunami hits land
Parts of Hawaii remain on alert as a tsunami triggered by a 7.7
magnitude earthquake off the west coast of Canada hits the
island chain.  Wave heights of three to six feet were predicted
in some areas, as "urgent action" was advised to protect lives.
The first waves were reported to be up to 2.5ft (76cm) in one
area.  Pamela Young, a presenter for local television station
KITV, warned that although the waves may be smaller than first
feared, local people remained cautious, concerned about the
effect of the undercurrents.
