Honolulu, Oct. 28 (Reuters): A tsunami warning prompted by a powerful earthquake off the Canadian coast sent 1 lakh people fleeing from shore to higher ground in Hawaii late yesterday, but an evacuation order was cancelled after a series of weaker-than-expected waves rolled through the islands.
The warning was downgraded to an advisory — a lower-level alert — shortly after 1am today (1100 GMT), though state civil defence authorities said beaches and harbours would remain closed for the time being, and residents were urged to stay away from the water.
There were no immediate reports of injuries, serious flooding or damage, but officials warned that abrupt changes in sea level and strong currents could still pose a hazard to swimmers and boaters.
“The threat may continue for several hours,” the Pacific Tsunami Warning Center said in its alert.
While scientists had warned early on that waves as tall 6 feet could occur in places, tsunami wave activity was reported to have peaked at just 2.5 feet at the island of Maui shortly after 10:30pm.
“The tsunami arrived about when we expected it should,” senior geophysicist Gerard Fryer told reporters, adding: “I was expecting it to be a little bigger.”
Tsunami warning sirens began blaring across the islands at about 8pm as state officials ordered a coastal evacuation, prompting a mass exodus that clogged roadways as motorists fled low-lying areas.
As the forecast arrival time of the tsunami neared, Honolulu mayor Peter Carlisle announced that all police and emergency personnel were being pulled out from potential flood zones, leaving anyone defying evacuation orders to fend for themselves. He also urged motorists who remained caught in harm’s way because of gridlocked roads to abandon their vehicles and proceed on foot.
“If you are stuck in traffic, you might consider getting out of your car and consider walking to higher ground. You will have to assess your own situation, depending on where you are right now. Right now it is critical,” he said.
Shelly Kunishige, a spokeswoman for Hawaii State Civil Defense, said evacuation orders were lifted once the tsunami warning was downgraded. But a thorough assessment of flooding or damage could not be made until after daybreak, she said.
The warnings followed an earthquake with a magnitude of 7.7 that hit Canada’s Pacific coastal province of British Columbia late yesterday.
