Also known as “slow earthquakes,” the tremors are a phenomenon that occur along the Cascadia Subduction Zone every 12-15 months. The latest began Dec. 22, 2015, according to the seismic network. They subsided for a time, but resumed in the past several days.
The latest tremors were recorded in areas including South Kitsap, Olympia, and Tacoma.
Tremors are weighing heavily on the minds of many, especially in Alaska, where a magnitude-7.1 earthquake shook the south-central region. It was the strongest quake in decades in a region that is no stranger to them.
