Back in January 26, 1700, a M9.0 Cascadia megathrust earthquake struck the Pacific Northwest, sending a tsunami rippling through the pacific Ocean.
And just two days before that 320th anniversary, a M4.5 earthquake hit off Vancouver island, just 50-80 miles away from the terrifying subduction zone.
While we are preparing for the 320th birthday of the M9.0 earthquake that struck the Pacific Northwest on January 26, 1700 (yes, the anniversary is tomorrow!), a M4.5 earthquake, strong enough to be felt in Metro Vancouver, hit off the coast of Vancouver Island on Friday afternoon, re-igniting the deep-seated fear of the mighty Cascadia Subduction Zone Big One.
January 26, 1700: The M9.0 Cascadia megaquake
The shaking started around 9 p.m. on January 26 and lasted for at least 5 minutes. Can you imagine that nightmarish scenario? 5 minutes of intense rumblings, loud booms and cracks opening all around you.
The massive power of the quake created by a 600-mile rupture along a fault beneath the Pacific Ocean sent a tsunami rippling across the ocean.
The wave struck the coast of Japan around midnight on January 27, as shown in the below animation below.
So, yes on January 26, 1700, exactly 320 years ago this Sunday, occurred the most recent 9.0+ Cascadia Subduction Zone earthquake and according to specialists, it’s going to happen again… We just don’t know when.
M4.5 earthquake hits near the Cascadia on January 24, 2020
As already introduced above, the latest moderate quake that hit very near that devastating fault zone occurred on January 24, 2020, at 1:35 p.m. Pacific time, at a depth of 26 km (16 miles), off the west coast of Vancouver Island.
This M4.5 quake was felt, moved pictures, bottles, etc. by many in the Cowichan Valley, Victoria, Parksville/Qualicum and was reported over 600 times on the USGS website. Most of this magnitude off of the West Coast Vancouver Island are not felt.
The tremor was B.C.’s second of the year, following a burst of seismic activity at the end of December.
Fortunately, Friday’s quake was not the feared Big One. But there’s still a 5% chance of it being followed by a larger quake in the next few days.
Cascadia Earthquake Preparedness Week: January 26 to February 1
Gov. Kate Brown is expected to declare January 26 to February 1 as Cascadia Earthquake Preparedness Week.
In her latest speech she insisted on the following:
“When the next large-scale Cascadia earthquake and tsunami strike the Pacific Northwest, Oregon will face the greatest challenge of our lifetimes.
To be ready to recover, we must be aware and prepared. In the aftermath of a large-scale natural disaster, Oregonians will have to count on each other in the community, in the workplace, and at home until first responders are able to reach them.
I urge everyone to start conversations this week with their families, friends, and loved ones about how to be safe and as ready as possible, especially by having two weeks of ready supplies.”
Just get prepared and be ready if you want to survive the next Cascadia devastating earthquake that could hit anytime. Read similar earthquake preparedness news and stories on Strange Sounds and Steve Quayle. [USGS, VancouverSun]
