The Seattle Fault Line Significant damages will be done

The Seattle Fault has been active three or four times in the past 3,000 years and when it becomes active again, it will lead to a series of events causing great damage to the Pacific Northwest region. According to the Washington Geological Survey, the Puget Sound will eventually get hit with a huge tsunami following a 9.0 earthquake along the West Coast, but that is a different issue. The Seattle Fault Line runs through Kitsap County, which is a major fault zone. This earthquake is going to cause some serious damage and it’s worth looking into the damages it’s going to cause and what is needed to prepare.

Picture this; It’s a typical Thursday morning in the Puget Sound. Suddenly you feel the ground start to shake. The earthquake is here. Buildings are shaking, windows are shattering, and everything around you is tumbling down. The earthquake and tsunami will come with no warning, and it is predicted to be one of the largest catastrophic events in centuries. It will bring destruction greater than ever seen before in the region. Scientists have records from 1,000 years ago that indicate that an earthquake with a magnitude of 7.0 and a tsunami came crashing through in the Puget Sound. As a result of the earthquake, the seafloor created a huge landslide underwater, causing a massive tsunami due to displacement in the water. This came from Seattle and raged through the Kitsap Region. It resulted in a 22-foot uplift of the south end on Bainbridge Island.

During the first minute of the earthquake, the shaking begins and everyone gets forced to the ground, and daily life begins to stop. Land on the south will be raised 20 feet, due to the fault being located right under the south side of the Island. Power lines will fall, sewer lines will burst, reception will go black, and all communication systems will fail. The Agate Pass Bridge might fall, and all ferries will stop due to large waves crashing through the sound. Soil liquefaction (saturated soil loses stiffness in response to shaking and becomes a liquid) will begin in areas like South Bainbridge and East Bremerton.

During minute two, the shaking earth will bring the tsunami to life. Waves will start to rise and the water will come plowing into buildings, creating floods in low areas. The tsunami will reach 13 feet near the north shore of Dyes Inlet in Silverdale. Not every tall building will be safe, the earthquake will also trigger landslides throughout the region and cause significant devastation. Large landslides will create small tsunamis heading in the direction of already damaged shores. Small fires will be ignited as gas lines are broken, and flames will be spread all over the area. Buildings will be damaged as most are not up to the current seismic codes.

After minute ten, thousands of people will be trying to get home or reaching out to loved ones. Many roads will be closed, but some highways will be accessible. Agate Pass Bridge may or may not fall (there is no way of finding if it will uphold during the earthquake) but the Bridge is currently not up to date on seismic codes. Thousands of people on the peninsula work in Seattle and will be unable to get home in theses conditions because the ferries will be out of commision due to the quake. News of the big earthquake and tsunami will spread quickly throughout the world. The well-being of all people will be the number one priority, involving survivors in the rumble and getting everyone to safety.

The Federal Emergency Management Agency is constantly trying to present new ideas and bring awareness to the damage the Seattle Fault Line will cause. Every year more and more buildings are becoming seismic certified and becoming safer. We need to take into account that this earthquake is going to happen and it will change things permanently. It’s time to prepare and get ready if this earthquake comes anytime soon, and you know it will.
