Preparing for Disaster
April is Emergency Communications Month at the Cybersecurity Infrastructure & Security Agency (CISA).
With its verdant landscapes and bustling cities, the Pacific Northwest is also home to one of the most significant seismic threats in the United States: the Cascadia Subduction Zone. Stretching from northern Vancouver Island to northern California, this fault line represents a geological boundary and a looming challenge for Vancouver, WA, and Portland, OR.
The Cascadia Subduction Zone, where the Juan de Fuca Plate is sliding beneath the North American Plate, has a history of producing massive earthquakes with magnitudes up to 9.0 or higher. The last such event occurred in 1700, sending a tsunami across the Pacific and jolting the region with ground-shaking of several minutes. Today, the implications for Vancouver and Portland metropolitan areas could be catastrophic, with scientists estimating a 1 in 3 chance of a significant quake in the next 50 years.
The risks associated with such an event are manifold. Infrastructure, much of which was built before the advent of modern seismic standards, could suffer extensive damage. This includes bridges, roads, and buildings, potentially isolating communities and hampering emergency response efforts. The economic impact could be staggering, with estimates suggesting billions of dollars in damages.
Moreover, the region's geography exacerbates the risk. The soft soils along the Columbia River, which both cities straddle, are particularly susceptible to liquefaction—a process where solid ground behaves like a liquid during intense shaking. This could lead to the collapse of structures, the severing of utility lines, and even landslides, further complicating rescue and recovery operations.
There are always risks of disaster. Whether it’s from earthquakes, forest fires, or a utility outage, this is the big one that keeps me up at night. I wonder how well the companies I work with will be prepared, specifically when communicating with employees and customers during a crisis. Now’s a good time to review IT Disaster Recovery Plans (DRP’s) and think about how emergency communication would go without Internet, mobile, text, and landline service; how would the business concern keep functioning?
In conclusion, while the beauty of the Pacific Northwest is undeniable, so is the threat posed by the Cascadia Subduction Zone. It underscores the need for continued investment in seismic research, building retrofits, and emergency preparedness efforts. For residents of Vancouver and Portland, understanding and preparing for these risks is not just prudent—it's imperative.
