The Cascadia subduction zone in the Pacific Northwest has been accumulating tension for over 320 years, with a predicted magnitude 9 earthquake, 45 times more powerful than California's 1906 quake.
Locals refer to this anticipated earthquake as "The Big One," with a 37% chance of occurring within the next 50 years.
Subduction zone earthquakes can trigger tsunamis capable of wiping out coastal communities, as seen in Japan's 2011 disaster following a magnitude 9 quake.
Japan's preparedness for earthquakes minimized building destruction but underestimated the tsunami's impact, resulting in 16,000 deaths.
The Cascadia subduction zone, stretching 600 miles from California to British Columbia, has experienced 41 quakes in the last 10,000 years, with the last one occurring in 1700.
The impending Cascadia earthquake could cause up to five minutes of violent shaking and a tsunami reaching a hundred feet in some areas.
Portland officials are planning a new Burnside Bridge and upgrading structures to earthquake standards, but most homes are unprepared and not bolted to foundations.
Recommendations for earthquake preparedness include retrofitting homes, securing furniture and appliances, and having essential supplies like water, food, fire extinguishers, and a gas shutoff tool.
