2026-04-18 – Steve Angster – Unraveling the Seattle fault zone: Main and secondary fault dynamics
The Lecture – Unraveling the Seattle fault zone: Main and secondary fault dynamics The Quimper Geological Society (QGS) is excited to have Steve Angster from the Seattle office of the U.S. Geological Survey to present details about the mapped faults within the Seattle Fault Zone (SFZ). The SFZ is a complex system of south-dipping thrust faults and associated secondary structures that collectively accommodate north–south shortening beneath the central Puget Lowland. While the main Seattle Fault has long been recognized as a significant seismic hazard, growing evidence suggests that deformation is distributed across a broader zone of subsidiary faults that may… Read more2026-04-18 – Steve Angster – Unraveling the Seattle fault zone: Main and secondary fault dynamics

ABOUT US
Our goal is to foster an understanding of Earth Science concepts by offering five-eight (5-8) illustrated lectures during the academic year and one or two summer field trips. We focus mainly, but not exclusively, on local and regional geologic features and issues (see yearly list under events). Membership and events are FREE and open to the public, although we gratefully accept donations to defray our expenses. QGS is an earth-science activity of the Jefferson Land Trust, which is located in Port Townsend, WA. We are in our 10th year here on the Quimper Peninsula.

We do not share your information with anyone beyond the Jefferson Land Trust and will send only geology-related information. You can always unsubscribe if you wish.
