Geologic Hazards
in
 Washington State
Figure1: Earthquake Hazards in Washington State (Cakir and Walsh, 2007).
The state of Washington experiences earthquakes almost on a daily basis. A reason for this could be
because of its proximity to the Cascadia Subduction Zone. As we can see from the map the areas
closest to this fault experience high shaking hazard.
According to Aftwater, Satake, and Wang (2003) an earthquake of magnitude 9 occurred in the year 1700 along the
Cascadia Subduction zone. This earthquake is possibly one of the largest earthquakes to occur near the state of
Washington. The evidence of the effects of a tsunami  which hit the Japanese coast at approximately the same time
helps in supporting this argument. Another major earthquake is inevitable along this subduction zone but scientists have
not yet been able to predict when this earthquake is expected.
According to Falde (2021) the prolonged ground shaking as
well as the tsunami which occurred as a result of the
Cascadia earthquake of 1700 is responsible for altering the
Pacific Northwest in the United States. If a similar
earthquake of magnitude 9 had to occur today the loss to
the state of Washington is approximated to be around 49
Billion dollars. The major damage caused by earthquakes in
Washington is due to liquefaction, and upliftment and
subsidence along the fault.
Figure 2: Damage due to earthquakes  (www.dnr.wa.gov)
Figure 3: Earthquake Safe Building Made From Wood. (University of California San Diego, 2017)
One of the main measures taken to reduce damage to earthquakes is adequate mapping. By
mapping areas prone to land failure and liquefaction damage can be mitigated. Earthquakes occur
frequently in Washington even though they are of lesser magnitude and so the communities need to
participate in earthquake preparedness programs. Earthquake prone areas need to be studied
carefully and sensible decisions need to be made regarding land use, engineering and construction
design to reduce earthquake damage.

Over the past years the state of Washington has
experienced many tsunamis. Most of the prominent tsunamis
that hit this state had been triggered by landslides.
According to Chague-Goff and Goff (2014) one of the most
destructive tsunamis that hit this state was the 1820's
tsunami.  A landslide that occurred in the Camano island
resulted in pieces of land falling into the ocean. This
triggered a violent tsunami that hit Hat island and drowned
many of the local people there
Figure 4: Tsunamis in Washington (www.dnr.wa.gov)
The tsunamis which are created by a distant earthquake or landslide will travel through the ocean. These tsunamis
mainly affect the Pacific coastal communities and it takes hours for the public to safely evacuate the area.
Tsunamis created as a result of the Cascadia subduction zone also affect the Pacific coastal communities. In this
case, evacuation can be completed within tens of minutes.
