No tsunami risk in B.C. after earthquake near Alaska: officials
Officials have determined there is no risk of a tsunami in B.C. after a 7.3-magnitude earthquake rattled off the coast of Alaska Wednesday, according to officials.
EmergencyInfoBC posted to social media just before 2 p.m. telling people to 'stand by for B.C.-specific info.'
Roughly 20 minutes later, an update advised there was no danger of a tsunami hitting B.C.
A tsunami warning is, however, in effect for portions of Alaska. The quake was located roughly 80 kilometres south of Sand Point, measured at a depth of approximately 35 kilometres, according to U.S. officials.
The warning covers parts south Alaska and the Alaska Peninsula, from Kennedy entrance to Unimak Pass.
The U.S. National Weather Service uses a four-level ranking system to inform the public about tsunami risk, with a warning representing the highest level of danger.
'A tsunami warning is issued when a tsunami with the potential to generate widespread inundation is imminent, expected, or occurring,' according to the U.S. Tsunami Warning System.
'Warnings alert the public that dangerous coastal flooding accompanied by powerful currents is possible and may continue for several hours after initial arrival.'
Additionally, warnings trigger emergency officials to 'take action' which can include evacuations, where necessary.

An Alaska tsunami warning had residents scrambling for high ground after 7.3 magnitude earthquake
ANCHORAGE, Alaska — Communities along a 700-mile (1,127-km) stretch of Alaska's southern coast ordered residents to higher ground after a powerful offshore earthquake Wednesday, but officials quickly downgraded and then canceled a tsunami warning for the region. There were no reports of significant damage. The earthquake, with a preliminary magnitude of 7.3, struck at 12:37 p.m. local time south of Sand Point, a community of about 600 people on Popof Island, in the Aleutian chain, according to the Alaska Earthquake Center. 'We have seen other earthquakes in the area that have not generated significant tsunami waves, but we're treating it seriously and going through our procedures, making sure communities are notified so they can activate their evacuation procedures,' said Jeremy Zidek, a spokesperson for Alaska's emergency management division. The quake was felt as far away as Anchorage, almost 600 miles (966 km) to the northeast. The National Tsunami Warning Center issued a warning for an area stretching from about 40 miles (64.4 km) southwest of Homer to Unimak Pass, a distance of about 700 miles (1,126 kilometers). Among the larger communities in the area was Kodiak, with a population of about 5,200. The warning was downgraded to an advisory about an hour later, and canceled just before 2:45 p.m. The highest water level generated by the earthquake in Sand Point was not quite 2.5 inches (6.3 cm) above the tide, the center said. 'There's no damage at the airport, doesn't appear to be any damage at the harbor, no damage to speak of, really,' Sand Point Police Chief Benjamin Allen said. There was some damage -- in the form of broken bottles -- at the Alaska Commercial general store in town. Manager Vickey McDonald said about half of the store's alcohol aisle had crashed and shattered. 'I've got liquid smoke and barbecue sauce and pickles ... broken on the floor,' McDonald said. 'It smells horrendous in here.' In Unalaska, a fishing community of about 4,100, officials urged people in possible inundation zones to move at least 50 feet above sea level or 1 mile (1.6 km) inland. In King Cove, which has about 870 residents on the south side of the Alaska Peninsula, officials sent an alert calling on those in the coastal area to move to higher ground. Tourists Jodie Stevens and her husband, Aaron Park, were looking at the puffins at the Alaska SeaLife Center in Seward when they heard someone yelling that there had been an earthquake and they needed to evacuate. They walked a few blocks uphill in the rain, with a woman from the center yelling to those they passed to get to higher ground. They were about halfway to the official high ground spot when they heard a siren signal that all was clear, she said. The National Weather Service said in posts on social media that there was no tsunami threat for other U.S. and Canadian Pacific coasts in North America, including Washington, Oregon and California. Alaska's southern coast is earthquake-prone, and Wednesday's was the fifth in roughly the same area since 2020 exceeding magnitude 7, state seismologist Michael West said. 'Something's moving in this area,' he said. 'I would not call this an isolated earthquake. It appears to be part of a larger sequence spanning the last several years.' That has the attention of seismologists, he said. 'This area has been and remains capable of larger earthquakes and earthquakes capable of significant tsunami damage,' he said.

Gulf Coast braces for flooding as storm system builds into possible tropical depression
This GOES-19 GeoColor satellite image taken Wednesday, July 16, 2025 at 12:46 EDT and provided by the National Oceanic and Atmospheric Association, shows a tropical weather system over the Florida Panhandle. (National Oceanic and Atmospheric Association via AP) The weather system moving across the Florida Panhandle on Wednesday was showing a greater chance of becoming a tropical depression as it moves toward the northern Gulf Coast, according to the National Hurricane Center. The system has a 40 per cent chance of becoming a tropical depression as it moves west over the Gulf toward southeastern Louisiana on Thursday, the federal agency said. The severity of its impact will depend on how far it travels offshore, where conditions are ripe for a tropical depression, before reaching Louisiana. The tropical weather will affect Alabama and Mississippi as well. Regardless of whether the system intensifies, heavy downpours could cause flooding, officials warned. New Orleans is bracing for three to five inches (eight to 13 centimetres) of rain through Saturday, but some areas could see as much as 10 inches (25 centimetres), especially near the coast, the National Weather Service said. 'While a tropical depression cannot be ruled out near the coast on Thursday, the main focus remains the heavy rain threat,' the agency wrote on X. Volunteers and local elected officials played music as they shoveled sand into bags to hand out to residents in New Orleans on Wednesday morning at the Dryades YMCA. 'My street flooded just the other day when we got a little bit of rain and so I want to just make sure that I'm proactive,' New Orleans resident Alex Trapps said as he drove away with sandbags in his car. The looming threat in the southeast comes on the heels of a series of lethal floods this summer. On Monday, flash floods inundated New York City and parts of New Jersey, claiming two lives. And at least 132 people were killed in floodwaters that overwhelmed Texas Hill Country on the Fourth of July. The system percolating over Florida will be called Dexter if it becomes a named storm. Six weeks into the Atlantic hurricane season, which runs from June 1 to Nov. 30, there have been three named tropical storms — Andrea, Barry and Chantal — but no hurricanes. Chantal made landfall in South Carolina last week, and its remnants caused flooding in North Carolina that killed an 83-year-old woman when her car was swept off a rural road. The National Oceanic and Atmospheric Association said in May there was a 60 per cent chance that there will be more named storms this hurricane season than there have been in past years on average. The currently developing weather system is expected to move fully inland by the end of the week. Southern Louisiana — a region all too familiar with the potentially devastating impacts of flooding — is expected to be hit hardest Thursday and beyond. Erika Mann, CEO of the Dryades YMCA, said that local elected officials managed to organize the storm supply distribution within a day after the threat intensified. 'We open our doors and help the community when the community is in need,' Mann said. Some residents who came to get supplies 'jumped out of their cars and they helped. And it just represents what New Orleans is about. We come together in crisis,' Mann said. Safiyah Riddle, The Associated Press
