In coming: A tsunami surge in Okoromai Bay on the Whangaparaoa Peninsula photographed by John Briand of Army Bay at about 4.10pm last Saturday. He says
people were in the water despite Civil Defence warnings.
Surges hit shore
THERE is further proof that
tsunami waves generated by last
Friday's magnitude 9.0 Japan
earthquake reached all New Zea-
land beach fronts, including Rod-
ney, the Hibiscus Coast and the
Bigger surges often arrived much
later than expected.
New data from NIWA shows
waves arrived as expected -- even on
a Scott Base sea-level gauge in
Results from 19 sea-level gauges
show peak wave amplitudes -- the
height of the wave above predicted
tide levels -- ranged from 0.78
metres at Whitianga, Kaingaroa in
the Chatham Islands and Timaru
to 0.05 metres in Scott Base.
The largest waves at 1.6 metres
were the first two sites, while Mt
Maunganui (Moturiki Island),
Charleston near Westport, and
Timaru also recorded heights over a
The first waves to hit New Zea-
land were at least 12 hours after the
earthquake first struck Japan at
5.46pm New Zealand time.
The highest waves recorded didn't
arrive at most sites until well after
the first -- 33 hours later in Sumner,
The height at Marsden Pt in
Whangarei, one of the nearest
measuring points to Rodney and the
Hibiscus Coast, was about 0.6
metres and waves were arriving
about every half hour on Saturday.
The delay in arrival of the largest
waves from a distant tsunami
source is due to waves bouncing off
continental shelves around the
Pacific, including South America
and local coastal headlands and off-
shore ridges, diminishing slowly
over several days.
It's important to understand
that tsunami waves can continue
for some time after the first few
waves hit,'' NIWA principal scien-
tist Dr Rob Bell says.
It's not safe to assume that once
you have seen one wave, the risk
subsides and all returns quickly to
normal. We are still recording obvi-
ous wave heights at our sea-level
gauges now, days after the earth-
quake, which are affecting currents
in harbours and estuaries,'' he says.
The size and timing of the waves
recorded by the sea-level gauges are
similar to those estimated in the
response phase of this event. The
accuracy of this information is vital
for Civil Defence and emergency
management when they are making
decisions about tsunami warnings,
to ensure the hazardous impacts of
a tsunami event in New Zealand are
Sea-level gauges around New
Zealand are operated by agencies
including NIWA, port companies,
regional and district councils.
