(Kathryn Marlow/CBC)THE LATEST: Residents of much of coastal B.C. have been asked to avoid beaches and shorelines after a tsunami advisory was issued late Tuesday. An advisory is the second step in a three-tiered warning system, and it means strong currents are likely. Officials say an advisory means significant flooding isn’t expected, but strong currents could be dangerous for those near the water. The advisory covers B.C.’s central and north coasts, Haida Gwaii and the west and northeast coasts of Vancouver Island. It also spans Juan de Fuca Strait and Greater Victoria, including the Saanich Peninsula. The District of Tofino on Vancouver Island had expected tsunami activity to reach the community overnight. Residents have been urged to avoid shorelines and beaches after a tsunami advisory was issued for multiple parts of the B.C. coast following a large earthquake in the Pacific basin near Kamchatka, Russia, on Tuesday afternoon.Tsunami activity was expected to cause strong currents and waves in some regions of coastal B.C. late Tuesday night into Wednesday morning, with emergency officials saying that tsunami waves arrive in a series and the first of them may not be the biggest.The U.S.-based National Tsunami Warning Centre says there was a magnitude 8.8 earthquake, with B.C. officials saying it occurred around 135 kilometres southeast of the Russian city of Petropavlovsk around 4:25 p.m. PT.A tsunami advisory, upgraded from an earlier watch, was issued for B.C.’s north and central coasts, including Kitimat and Bella Coola, Haida Gwaii and the west and northeast coasts of Vancouver Island.It also spanned the Juan de Fuca Strait from Jordan River to Greater Victoria, including the Saanich Peninsula.B.C.’s tsunami zones are listed in this graphic from EmergencyInfoBC. On Tuesday, a tsunami advisory was issued for Zones A through D. (EmergencyInfoBC)A tsunami advisory means residents should move away from the ocean and stay alert for more instructions from officials.”Significant inundation is not expected for areas under an advisory, but coastal zones may be at risk due to strong currents,” reads an Emergency Info B.C. advisory.For Tsunami Notification Zones A, B, C, & D currently under Tsunami Advisory: • Stay out of the water. DO NOT go to the shore to observe currents or waves• Avoid low-lying coastal areas, harbors, marinas & beaches until emergency officials say it is safe• Monitor for… https://t.co/rMo16swgLj pic.twitter.com/9siotR5snt—@EmergencyInfoBCThe advisory adds strong waves and currents could drown or injure people who are in the water, and currents at beaches, harbours, marinas or bays could be especially dangerous.It had earlier advised boat operators in areas under a tsunami watch to move their boats out to sea to a depth of at least 55 metres if time and conditions permit, and avoid shallow water and inlets if they are already at sea.A tsunami warning, which is the highest level, means that residents should move away from the water immediately.This graphic shows the three-tiered tsunami warning system used by officials in B.C. As of Tuesday night, most of the B.C. coast is under an advisory. (EmergencyInfoBC)Taimi Mulder, an earthquake seismologist with Natural Resources Canada, said that even if forecasted tsunami wave heights were small, people should heed the warnings to stay away from the water.”One still wants to be away from the water, and the water’s edge, at that time,” she told CBC News late Tuesday night.”Because unpredictable things could happen, and the currents will be much stronger than normal, and the water will be more confused-looking than normal.”WATCH | Tsunami warnings issued after quake: Massive earthquake near Russia triggers tsunami warningsAn 8.8 magnitude earthquake in eastern Russia caused widespread tsunami warnings as far away as Japan, Hawaii and the B.C. coast. Tofino beaches closedThe District of Tofino on the west coast of Vancouver Island said in an emergency notification around 7 p.m. PT that people shouldn’t go to the shore to observe the waves, and later told CBC News in an email that it had closed all beaches until further notice.Emergency Info B.C. says Langara Island, off the coast of Haida Gwaii, saw tsunami waves around 10:05 p.m. PT, but the wave height was forecast to be less than 30 metres.Early Wednesday, the U.S. National Oceanic and Atmospheric Administration updated its tsunami bulletin to include regional observations, and for B.C., that included an “observed maximum tsunami height” of 27 centimetres at Winter Harbour, and 21 centimetres at Tofino. The Tofino coastline is seen from above in this stock image. The community on the west coast of Vancouver Island said that tsunami activity was forecast to reach it by 11:30 p.m. PT on Tuesday. (fokke baarssen/Shutterstock)John Cassidy, another seismologist with Natural Resources Canada, said Tuesday’s earthquake was the type of seismic movement that was most likely to generate a tsunami.”Those waves can travel across the Pacific…. They can travel a long way when they’re out in the open ocean,” he told Jason D’Souza, host of CBC’s All Points West, just before 6 p.m. PT on Tuesday.”The tsunami waves travel at about the same speed as a jet,” he added.WATCH | When the first tsunami watch was issued for much of B.C.’s coast: Massive earthquake in the Pacific Ocean prompts a tsunami watch for parts of B.C.CBC’s Darius Mahdavi reports on a massive earthquake in the Pacific Ocean which has led to a tsunami watch in parts of B.C. If the magnitude of 8.8 is confirmed, the earthquake would be among the top 10 strongest earthquakes recorded since 1900, according to the U.S. Geological Survey.It would be the strongest earthquake since the devastating 2011 earthquake that struck near the Tōhoku region of Japan, which had a magnitude of 9.0 and triggered a tsunami wave more than 40 metres high.”It’s a larger earthquake than we’ve seen,… in my lifetime anyway, that’s that close [and] could potentially affect our B.C. coast,” said Elmer Frank, chief councillor of the Tla-o-qui-aht First Nation, whose traditional territories encompass Tofino and Ucluelet on Vancouver Island.Frank said Tuesday’s earthquake and tsunami scare is a reminder for his community to keep up on emergency drills and preparedness.Elmer Frank, chief councillor of the Tla-o-qui-aht First Nation, said the nation regularly communicates with its members about what needs to be done in an emergency situation. (CBC)No major tsunami expected to hit HawaiiThe U.S. Geological Survey, in an updated measurement on Tuesday evening, said the quake hit at a depth of 20.7 kilometres.In the U.S. state of Hawaii, waves of up to 1.7 metres impacted the islands before the Pacific Tsunami Warning Centre reduced its warning level for the state late Tuesday, saying no major tsunami was expected.Dennis and Devin Delatorre stand in the back of their truck waiting to return home on Tuesday after evacuating their Ewa Beach home in Kapolei Regional Park, Hawaii. (Michelle Bir/The Associated Press)”Initial wave impacts from the leading edge of the tsunami measured several feet at some monitoring stations, but ‘follow-up’ waves over the next several hours are often larger,” said Maui County in a recent update. Cars jammed streets and highways in Hawaii’s capital of Honolulu, with standstill traffic even in areas away from the shoreline.Ports on the Kamchatka Peninsula in Russia near the 8.8 magnitude quake’s epicentre flooded as residents fled inland, and frothy, white waves washed up to the shore in northern Japan.People went to evacuation centres in affected areas of Japan, with memories fresh of the 2011 earthquake and tsunami that caused reactor meltdowns at a nuclear power plant. No abnormalities in operations at Japan’s nuclear plants were reported Wednesday.Russian authorities said several people were injured, without giving a figure.
