In the early morning of January 23rd some Victorians woke up to their cell phone or landline ringing with a VicAlert call, some received a text, some got calls from relatives or friends. And others slept through the whole thing and awoke wondering what they’d missed. I think what all of us felt was a little vulnerable and a little scared, with pictures in our minds of big waves engulfing entire cities.

I awoke from a very early morning phone call from our Acting City Manager letting me know that she had followed the City’s emergency management protocol and set up an Emergency Operations Centre (EOC) at Fire Hall #1. I hopped out of bed, got dressed and walked the three blocks to the fire hall to join the City’s senior leadership team in the EOC.

In order to be better prepared as a community and to understand the risks that face us, here are some thoughts, reflections and lessons learned. It’s a bit wordy but packed with important details. Please read and please share with your family, friends and neighbours.

What does a Tsunami mean for Victoria?
A tsunami in Victoria is not a big wave. The City has done tsunami modelling and it shows for the City of Victoria it is a slow water level rise, of approximately 1.5 to 3.5 meters. The maximum water level rise is 3.5 metres with a water flow speed of one metre per second. This means that the people who would be affected are those living within a maximum of two blocks of the ocean in low-lying areas pictured on the map above.

In comparison, the 2011 Tohoku earthquake in Japan had a maximum water level of 40 metres with a water flow speed of 12 metres per second.

What did the City do in the early morning of January 23rd?
Residents were notified of the warning through a number of channels including an emergency takeover of our website, social media and the VicAlert notification system.

Emergency responders were deployed and had started door-to-door notifications in the potentially affected areas based on our tsunami modeling. Victoria Ready volunteers were setting up a reception centre at the Fairfield Community Centre when we received notice at 4:30am the EOC that the warning – of the tsunami that had been predicted to arrive in Victoria around 5:50am – had been cancelled.

As Connect Rocket, the provider of the City’s VicAlert program put it in a tweet the next day, “Always lessons to be learned but @CityofVictoria got it right opting for targeted notifications. No benefit to anyone if evacuation routes become clogged by unnecessary traffic. These are tough calls and their team nailed this one.”

What is VicAlert and How Does It Work?
VicAlert provides you with important emergency information, such as imminent threats (e.g. severe weather, power outages, tsunami), AMBER alerts, and local incidents that affect specific areas of Victoria. The service enables emergency notices to be disseminated City-wide or to targeted areas, which can be helpful for neighbourhood-specific emergencies such as a gas leak.

When you sign up for VicAlert, you receive emergency updates and helpful instructions where you are, when you need them. You have the option to receive notifications by cell phone, landline, and email. Because emergencies can happen at any time, it’s a good idea to include the phone notification – and list your landline and cell phone numbers. A phone call in the middle of the night may wake you, while a text may not.

During the January 23rd tsunami warning notifications through VicAlert were only sent out to potentially affected areas. If residents selected to be notified only for certain neighbourhoods and didn’t receive a message, they were not in an area notified for evacuation. You can easily change your profile to select all neighbourhoods and receive all alerts in the future.

We are encouraging all residents to sign up for VicAlert in the wake of this warning, and suggest using both mobile and landlines where possible to ensure multiple methods of notification in the event of an emergency. Subscription to this service has increased from 6500 people before the tsunami warning to close to 50,000 people since.

In April 2018 a Province-wide “push” alert system that will automatically get in touch with each cell phone will be put in place by the Province. Here is a CHEK news story about that program.

Where do I go in an emergency?
The City of Victoria has identified potential buildings throughout the City that may be used for reception and group lodging centres. We don’t advertise these, as the locations will vary depending on the situation and suitability.  For example, after an earthquake these buildings will have to undergo damage assessments prior to their use and we do not want residents going to buildings if they’re not safe.  VicAlert, the City’s website, Twitter and local media will broadcast the appropriate locations for people to go depending on the circumstances.

Get a Siren!
On the morning of January 23rd while people were still recovering from panic mode, we heard many cries for the City of Victoria to get a siren. The City of Victoria is not at risk like coastal communities on the open water are such as Tofino and Ucluelet where there are sirens in place.  We do not expect a large fast wave like we’ve seen in places like Thailand and Japan. As noted above, what the Tsunami modelling shows for the City of Victoria is a slow water level rise, of approximately 1.5 to 3.5 meters.

We have the resources in place to issue tsunami warnings without a siren due to the lower risk, the slow water level rise, and the length of warning time we will receive after an earthquake has occurred.  Our emergency responders have the capacity to go door-to-door and use loud speakers in the small areas within the City of Victoria that the tsunami modelling has shown the water level will rise to.

This approach has the benefit of notifying affected residents and businesses with personal instructions rather than a siren that would be heard by thousands of unaffected people and lead to confusion about what to do.

We’re all in this together!
The communities that do best in disasters are ones where people have a sense of connection, belonging and resilience. The false alarm on January 23rd is an invitation for all of us  to learn more about preparedness. It’s also a good opportunity for us to get to know our neighbours better and find out what their needs would be in an emergency. Where are the seniors who may need our help? The parents with young children? The people with limited mobility? Preparing for emergencies before they happen is a good opportunity to build stronger communities.

  1. Thank you for the thorough review of our tsunami emergency response system. I wasn’t aware of the tsunami incident modelling and what it means should such an event occur. My family and I are well out of the impact zone, and that’s reassuring. Regardless, we’ll be signing up for Vic Alert. Thank you.

  2. I wonder if you have considered the impact of a serious tsunami warning on all your many visitors to Victoria? We had just arrived from the mainland hours before. We were alerted to this ominous threat by our son phoning us at 3am on the morning of January 23rd. After looking at the model of tsunami waves barreling southwards down the Pacific, we decided to quickly evacuate to higher ground, as were very close to the water near the Ogden Point area.
    Hindsight is a wonderful thing, but if faced with a similar threat I would still evacuate, whatever “model” human beings have devised. Some people were doing the same as us.
    Earthquakes could happen much closer to home than Alaska, with possible resulting tsunami.
    Could an advice sheet be put in the rooms of guests to your city? We felt totally uninformed, totally unprepared, and very scared.

  3. I understand the selective process of those at most risk to avoid the chaos on rapid response routes and yet if you data is incorrect there are many who will pay the price, including yourselves for the oversight. Maybe the environs of of the Esquimalt harbor, navy yards and the Gorge water way could be protected similarily to the tide surge and flood gates of Londons Thames river….. https://www.youtube.com/watch?v=Dvg2asACsG0 but maybe the cost of damage to that infrstructure will not balance the cost of a project of that magnetude.

    I trust we as the population of Victoria and the region have enough time for your practice attempts to get it right. You’re using words like 3.5 meters maximum (11.5 feet) with the same kind of surity that caused massive loss of life and 100’s of billion’s in damage in other parts of the world that thought they were ready too.
