As evidence we’re living in the future, next week’s issue of the New Yorker debuted online a week early and contains a somber warning entitled “The Really Big One,” which is about “the earthquake that will devastate Seattle.” In the piece, Kathryn Schulz details scientific findings and seismic predictions about exactly how devastating the next ‘big one’ will be for Seattle and the entire region of the Pacific Northwest. Spoiler alert: it’s really, really, really very bad.

Schulz’s warning piece might more accurately have been titled, “The Earthquake That Will Wipe The Pacific Northwest Coast Off The Map As We Know It.” In a nutshell, she reports that seismologists have determined that a giant earthquake will eventually occur in the Cascadia subduction zone, which runs along the Cascade Mountains. Called a “megathrust” earthquake, a seismic event of this magnitude would cause widespread devastation and kick off a tsunami that would obliterate everything west of I-5. In the PNW, as Schulz explains, that “covers some hundred and forty thousand square miles, including Seattle, Tacoma, Portland, Eugene, Salem (the capital city of Oregon), Olympia (the capital of Washington), and some seven million people.”

Schulz further reports that FEMA estimates a death toll of nearly 13,000 in the future Cascadia earthquake and tsunami, with another 27,000 injured and one million displaced from their homes. Compared to other natural disasters in recent history, a tragedy like this would be – in a word – overwhelming.

Predicting future earthquakes is, as you might imagine, a pretty tricky science. Geologists and seismologists study patterns in seismic activity and a host of other symptoms in an attempt to determine possible future events. However, the one thing that remains nearly impossible to predict is the timing. Unlike a weather event like a hurricane, which builds in strength over a period of time and allows experts to warn people in its path, earthquakes strike with little to no warning. (The exception for this might be in areas with heavy fracking activity, which has been known to cause earthquakes.)

Despite the weight of the bad news, most people seem to be taking the warning in stride. Seattle’s Post Intelligencer even took a slightly tongue-in-cheek stance in reporting on, well, the report. After all, the science says such an earthquake might not happen for 50 or even 1,000 years from now, and Seattlites are kind of known for not getting too worked up in the first place. But even though The New Yorker’s report isn’t necessarily cause to start running around freaking out, residents of the great Pacific Northwest will probably want to keep this information tucked away in case it becomes relevant. Say, when planning to build a home in the region. One might opt for architecture specifically designed to resist earthquake damage, although it’s probably not worth it, since everything will be wiped out by the tsunami anyway.
