A tsunami alert text from Victoria alert service Tuesday morning.
The City of Victoria is encouraging residents to sign up for their emergency alerts in the wake of Tuesday morning’s tsunami warning on Vancouver Island.
Early Tuesday morning, residents in Victoria and other cities woke up to text alerts warning them to go to higher ground after a 7.9-magnitude quake struck off the coast of Alaska. Environment Canada temporarily issued a tsunami warning that was cancelled around 4:30 a.m.

Sidney and North Saanich also have emergency messaging systems. The Sidney Fire Department is recommending residents attend a free open house at 7:30 p.m. at the Greenglade Community Centre to learn about emergency preparedness.

Emergency Info BC said in the event of a tsunami alert, some communities may activate their warning systems and other may choose to monitor the situation. It also said AlertReady, a province-wide system that notifies local municipalities of emergencies, will include text alerts by April 2018.
Many on social media posted on Tuesday they were not aware of the tsunami warning until after they woke up, well after the advisory had been cancelled. The City of Victoria said they made a mistake by only sending text and email alerts to mobile phones. while voice calls went to landlines for this morning’s alert. The city says in the future, they will send out alerts via text, email and phone calls to all phones assuming it is warranted.

Natural Resources Canada (NRC) says the first thing you should do when you hear or get a tsunami warning is to head for higher ground and not linger by the shore.
In deep water, the waves are less than a metre high but they can travel at speeds exceeding 800 kilometres per hour. When the waves reach shallow water or narrow inlets they slow down and can build into a wall of water that causes devastation on shore.

NRC says the first wave may not be the largest and successive waves may be spaced minutes to hours apart and continue for many hours.
