Breathtaking simulation shows potential tsunami in the Pacific Northwest (VIDEO)

Imagining a magnitude 9 earthquake in the Cascadia region

If there is an earthquake and subsequent tsunami, similar to the one in the simulation, what would occur here in Canada?

Smith stated, “An earthquake of this magnitude would cause a tsunami to reach heights of 30 to 20 meters along our western coastline, and impact the coasts around the Pacific Ocean, considering the rupture pattern and size of this earthquake.”

This indicates that municipal areas, particularly those exposed to open ocean and inlets, may be vulnerable to tsunamis.

According to Smith, coastal communities could experience low-level flooding if currents were “erratic and strong,” so people should generally stay away from marinas and beaches.

Smith stated, “During the earthquake, the communities on the west coast of Vancouver Island are expected to experience shifts in the Juan de Fuca and North American Plates, ranging from one to two meters.”

“The tremors caused by such an earthquake will be experienced hundreds, if not thousands, of kilometers away,” stated Smith.

“In the case of significant earthquakes, there are connected dangers of landslides, soil liquefaction, and tidal waves across a vast region.”

The last “big one”

“According to Smith, the most recent megathrust occurrence along the Cascadia Subduction Zone happened on January 26th, 1700.”

The fault is roughly located offshore, about 150 kilometers away, and there is a greater likelihood of large inland earthquakes (M~7) occurring every several hundred years. These damaging events occur on a roughly decadal scale and are much closer to major cities. However, the fault that is roughly located offshore every several hundred years also has a greater likelihood of large inland earthquakes (M~7) occurring on a roughly decadal scale with damaging events closer to major cities.

Smith stated that there have been four seismic occurrences with a magnitude of 7 or greater in the South Western region of British Columbia over the last 130 years.

Smith stated, “While small buildings saw little damage from the earthquake, large structures such as bridges and buildings incurred significant damage. The earthquake, which occurred within the last century, was the closest megathrust event within 120 km east of Anchorage, Alaska in 1964, with a magnitude of 9.2.”

Preventing earthquake damage

Smith stated, “It is crucial to get ready for these occurrences, and individuals must erect structures in adherence to building code regulations, as earthquakes are impossible to forecast.”

We encourage everyone to practice the 3-step process of Hold and Cover, Drop. This means grabbing onto the desk or chair as a piece of nearby furniture, getting low, and getting under it to prioritize your safety when experiencing an earthquake.

Smith suggests that individuals can also create their own emergency readiness kits.

Early warnings for earthquakes

In the coming year, a nationwide earthquake early warning system will be launched.

It will offer “dozens to hundreds of seconds of notice before the intense shaking from the earthquake arrives.”
