Slow earthquakes affecting southern British Columbia and northern Washington
have been occurring every 14 months or so over the last 10 years. The PNSN
has deployed additional seismometers to record expected tremor events to gain
insight into the process and into the stresses that eventually will lead to
the region's next major earthquake.
The next slow earthquake is expected to occur sometime between October and
November, 2006.
