I saw the 7.7 earthquake on my USGS alerts as I was heading off to bed Saturday night and the initial reports were that it was epicentered on land in the Queen Charlotte Islands, an area with a small population.  And I thought to myself, well as least we won’t have a tsunami!  Note to self…stay up a bit longer till USGS nails the location and the tsunami alert buoys have had a chance to note the water movements. Roger that!

Hawaii Tsunami

Hawaii was hit by a tsunami on Saturday night prompting the authorities to order at least 100,000 people on the island state to move to higher ground.

One of my favorite tweets from the Canadian EQ! Gotta love those Canadians!

The Pacific Tsunami Warning Center said the first tsunami wave was three feet high and less forceful than expected. Some forecasts had predicted a wave of up to six feet high. Other waves were expected.

The tsunami hit with little warning and an alert, issued at short notice due to initial confusion among scientists about the quake’s undersea epicenter, caused massive traffic congestion as motorists made a mass exodus from low-lying areas. The Warning Center had said the first tsunami wave would strike the islands at 10:28 p.m. Hawaii Standard Time.

Honolulu Mayor Peter Carlisle announced that all police and emergency personnel were being pulled out from potential flood zones shortly before the first wave, leaving anyone defying evacuation orders to fend for themselves. He urged motorists who remained caught in harm’s way due to gridlocked roads to abandon their vehicles and proceed on foot.

The Tsunami Warning Center said an estimated 100,000 to 150,000 people who live in Hawaii’s coastal zones had been urged to move to higher ground until after 10:30 p.m. Governor Neil Abercrombie issued an emergency proclamation for the state. The tsunami center cautioned that wave height could not be predicted and that the first wave “may not be the largest”. It said: “All shores are at risk no matter which direction they face”.

Canada Quake

The warnings followed a powerful earthquake with a magnitude of 7.7 that hit Canada’s Pacific coastal province of British Columbia late on Saturday.

The U.S. Geological Survey said the quake was centered 123 miles south-southwest of Prince Rupert at a depth of 6.2 miles.

The Earthquakes Canada agency said the quake in the Haida Gwaii region was followed by numerous aftershocks as large as 4.6 and that a small tsunami has been recorded by a deep-ocean pressure sensor.

In Hawaii, tsunami warning sirens could be heard blaring out across Honolulu, the state capital on Oahu, the state’s most populous island, prompting an immediate crush of traffic, with many motorists stopping first at service stations to top up with gasoline. At movie theaters, films were halted in mid-screening as announcements were made urging patrons to return to their homes. The last time Oahu had a tsunami warning was after the devastating Japanese earthquake of March 2011. On Honolulu’s famed Waikiki Beach, residents of high-rise buildings were told to move to the third floor or higher for safety.

Tsunami Warning Center Geophysicist Gerard Fryer said the tsunami had caught scientists by surprise. “We thought that the earthquake was on land and when we learned that it was deeper undersea and we gathered more information, we had no choice but to issue a warning,” he said As residents scrambled to reach higher ground on Oahu, at least four major road accidents were reported by the state Emergency Medical Services. More accidents were also reported on the outer islands.
