Wave heights of three to six feet were predicted in some areas, as "urgent action" was advised to protect lives. Hours later, the tsunami warning was downgraded and the state governor said Hawaii could count its blessings.
There were no immediate reports of damage on the Canadian coast following the earthquake. Wave heights of three to six feet had been predicted in some areas.
Tsunami alerts that were issued for coastal areas of Alaska and British Columbia were swiftly downgraded.

While href="http://ptwc.weather.gov/" title=" the Pacific Tsunami Warning Center " >the Pacific Tsunami Warning Center did not initially expect a threat beyond the immediate area, it later warned that a tsunami had been generated "that could cause damage along the coastline of all islands in the state of Hawaii."
Initially, href="http://ptwc.weather.gov/" > the Pacific Tsunami Warning Center said it did not expect a threat beyond the immediate area. The centre called for urgent action to protect lives and property. People living in areas considered to be at risk were urged to move to higher ground.
But later it issued a warning that a "tsunami has been generated that could cause damage along the coastline of all islands in the state of Hawaii." First waves hit the archipelago, made up of hundreds of islands spread over some 1,500 miles, from around 22:30 local (08:30GMT).
First waves hit the archipelago from around 22:30 local (08:30GMT) onwards. A senior scientist at the Pacific Tsunami Warning Centre, Gerard Fryer, told journalists that while the tsunami had arrived as predicted, he had been "expecting it to be a little bigger."
"Urgent action should be taken to protect lives and property," the warning said. People living in areas considered to be at risk were urged to move to higher ground. A civil defence source tweeted that Wailoa Harbor on Hawaii island was reporting 4ft waves every six minutes.
After the first wave struck, Hawaii's Lt Governor, Brian Schatz, tweeted that water was now receding in Hilo Harbour, on Hawaii or 'Big Island'. The Pacific Tsunami Warning Center said, in an announcement posted at 00:54 local, that the tsunami warning was cancelled.
But he also reminded people that the first wave was not usually the biggest, and that surges could continue for six to seven hours. "Based on all available data, the tsunami threat has decreased and is now at the advisory level and not expected to increase.
Initial local media reports from around the islands suggested that wave heights recorded so far had generally been about six inches, with 2.5ft in one place - Kahului Harbor. "Sea level changes and strong currents may still occur along all coasts that could be a hazard to swimmers and boaters as well as to persons near the shore at beaches and in harbours and marinas. The threat may continue for several hours," it said.
A senior scientist at the Pacific Tsunami Warning Centre, Gerard Fryer, told journalists the tsunami had arrived as predicted, but he had been "expecting it to be a little bigger." In the wake of the cancellation, police began reopening roads and people in low-lying areas area were being allowed home, local media reported.
About an hour after the tsunami surges started, Honolulu Mayor Peter Carlisle told KITV News it was too early yet to give the all clear for people to move back. "We want to make certain that everybody understands this advisory now. The water is still treacherous; the water is still dangerous but we can go home and, as I say, we can count our blessings here in Hawaii," Governor Neil Abercrombie said.
He said further information had to be evaluated. "This is not an exact science," he said. Earlier, an eyewitness watching the beaches on Kauai island told the BBC that the waves were big and that a "strange mixture of fear and anticipation" reigned.

"A plane with a siren flew over ... and everyone left the beach and coastal buildings. All the boats have been taken out of the water. It's empty down there which is weird. People went buying gas and groceries," Mike Dexter-Smith said."A plane with a siren flew over ... and everyone left the beach and coastal buildings. All the boats have been taken out of the water.
