At 11:41 a.m. on August 20, 2013 a minor 3.6 earthquake shook the southern part of the Kitsap Peninsula in the Puget Sound. Komo News aired the story just after the shaking stopped and helped to ease the minds of the residents in the area. Some residents in the area were unaffected by the shaking and others are fairly concerned that it could be a pre-quake. Seismologists say that this is a just a reminder that the Puget Sound is an active area and earthquakes are common here.
Earthquakes actually happen in the Puget Sound everyday but most are to small for most of us to notice. Yesterday there was also a 1.7 earthquake in Seattle and a 1.8 earthquake in Belfair as well. Despite the looming volcano of Mount Rainer, many people here in the Puget Sound easily forget about the areas seismic potential as we often don’t feel them.
This minor shaking was enough though to take many people in the Puget Sound by surprise. Linda Swenson from Gig Harbor said "my windows started rattling really hard and then my walls shook and my floor... and it took me a while to figure out what was going on, at first I thought someone was at my door and was banging really hard and then I realized it felt like an earthquake." She added "my nerves are still shaking.”
Many people that felt the earthquake described it as lasting about 10 seconds of hard shaking. This hard shaking feeling is likely because the quake was very shallow and right off of the small fault line near Grapeview. It is possible that this minor quake is really just a pre-quake but the seismologists say that although this does increase the chance of a larger earthquake in the Puget Sound, that the chances are only slightly higher than they are any other day.
