'Most people think of a tsunami as something which is over reasonably quickly, but that is not always the case,' NIWA noted, saying that the event affected New Zealand for three to four days as waves bounced off undersea ridges and moved backward and forward along indented sections of the coast.

By DPA,
[RxPG] Wellington, Nov 23 (DPA) A tsunami created by a huge Russian earthquake last week raced to New Zealand at nearly 700 km an hour and caused waves higher than half-a-metre for three to four days, according to a scientific report released Thursday.
The initial wave caused by the Nov 15 quake, which registered 8.3 on the Richter scale in the Kuril Islands, took over 14 hours to reach New Zealand, the National Institute of Water and Atmospheric Research (NIWA) said.
But the highest rollers were on the east coast of the South Island, which was not affected until 40 hours after the first wave arrived in New Zealand waters.
'Most people think of a tsunami as something which is over reasonably quickly, but that is not always the case,' NIWA noted, saying that the event affected New Zealand for three to four days as waves bounced off undersea ridges and moved backward and forward along indented sections of the coast.
Around the Pacific, the tsunami impact was greatest at Crescent City in northern California, where a peak wave height of 1.76 metres caused strong, surging currents, damaging docks and boats in a marina, NIWA said.
