When people think of earthquakes in North America, they often think of California. You may recall images of the collapsed bridge from the 1989 Loma Prieta earthquake in Northern California. The LA region is also prone to moderately frequent earthquakes from the various fault lines that run through the area.
While California gets all the earthquake attention, the Puget Sound has its fair share of risk. Recently, there were over 4,100 recorded mini earthquakes west of Seattle called “episodic tremor and slip.” Scientists say these events happen every “14 months or so”. These earthquakes are so small that people would barely feel them, but are a good reminder that big and small quakes can happen in Western Washington.
The city of Seattle is near a dangerous “megathrust” fault line called the Cascadia Subduction Zone. This fault line begins off the coast north of Vancouver Island and ends off the coast of Eureka, CA. Major cities that are near the subduction zone include Vancouver, Seattle, and Portland. This zone is not usually particularly active, and many hundreds of years can pass without any significant seismic activity. However, this fault can cause considerable ground shaking along the entire Pacific Northwest coast.
Given that there is a risk of a major earthquake, all Seattleites should have an earthquake preparedness kit. While nobody can predict when an earthquake will strike or how large the magnitude of the quake will be, everyone can stock up on disaster supplies. It only takes a few minutes to assemble, and the package can make your life significantly easier when an earthquake does hit. Many people don’t have a kit at home because they are unsure of what to put in it. Here are five things you need to prepare ahead for a quake.
