No tsunami risk in B.C. after earthquake near Alaska: officials
A tsunami hazard sign is seen in Tofino, B.C., in this undated file photo. 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.

Powerful earthquake strikes Caribbean Sea, tsunami threat for some
A magnitude 7.6 earthquake struck in the middle of the Caribbean Sea, about 200 km south of the Cayman Islands on Feb. 8, 2025. The powerful quake, which struck 10 km below the Earth's surface, prompted the National Weather Service (NWS) Tsunami Warning System to issue tsunami alerts for coastal regions of the Cayman Islands, Jamaica, Cuba, Mexico, Honduras, Bahamas, San Andres and Providencia, Belize, Haiti, Costa Rica, Panama, Nicaragua, and Guatemala. "Earthquakes of this size are known to generate tsunamis dangerous to shorelines near the source," the NWS said in one of its statements. Many of the alerts have since been dropped, but tsunami waves 1-3 metres above tide level are possible along parts of Cuba's coast, and tsunami waves reaching 0.3-1 metre above tide level are possible along parts of the coasts of the Cayman Islands and Honduras. Tsunami advisories were issued for Puerto Rico and the Virgin Islands, but were lifted soon after. Luckily, since the earthquake was so offshore, there has been no immediate damage or injuries. There is no tsunami threat to the Gulf of Mexico or the Eastern Seaboard.

Powerful earthquake strikes Caribbean Sea, tsunami advisories issued
A magnitude 7.6 earthquake struck in the middle of the Caribbean Sea, about 200 km south of the Cayman Islands on Feb. 8, 2025. The powerful quake, which struck 10 km below the Earth's surface, prompted the National Weather Service (NWS) Tsunami Warning System to issue tsunami alerts for coastal regions of the Cayman Islands, Jamaica, Cuba, Mexico, Honduras, Bahamas, San Andres and Providencia, Belize, Haiti, Costa Rica, Panama, Nicaragua, and Guatemala. Many of the alerts have since been dropped, but tsunami waves 1-3 metres above tide level are possible along parts of Cuba's coast, and tsunami waves reaching 0.3-1 metre above tide level are possible along parts of the coasts of the Cayman Islands and Honduras. Tsunami advisories have also been issued for Puerto Rico and the Virgin Islands. "Earthquakes of this size are known to generate tsunamis dangerous to shorelines near the source," the NWS said in one of its statements. "The earliest estimated time that hazardous sea level fluctuations and strong ocean currents may begin in Puerto Rico and the Virgin Islands is 9:46 p.m. AST on Saturday, Feb. 8, 2025," the NWS later added. Any possible waves that do make it to shore for Puerto Rico and the Virgin Islands, however, are forecast to remain under 30 cm in height. Luckily, since the earthquake was so offshore, there has been no immediate damage or injuries. There is no tsunami threat to the Gulf of Mexico or the Eastern Seaboard.
