Analysis of central Washington seismicity of the past two decades reveals some interesting features. Shallow seismicity and deep seismicity occur as different geographic distributions. Concentration of seismicity along north- to northwest-oriented trends appears to be related to a buried continental rift and possible associated fault zones. Hypothesized extensions of the Chiwaukum graben and Straight Creek fault systems are plausible structural controls on the seismicity.
