2024-11-16 Megan Anderson – Siletzia’s influence on the Seattle Fault
The Lecture: What Happens When You Crash Iceland into North America? A view of Washington 50 million years ago… The Puget Lowland of Washington State contains several potentially dangerous seismic faults, including the Seattle fault, which runs south of downtown Seattle. To accurately assess the earthquake hazard in this region, we need to understand the architecture and geologic history of the rocks that host these faults, deep below the Puget Lowland. Geologists do this by using small changes in Earth’s gravity and magnetic fields to create images of the Earth’s subsurface. These rocks formed in a subduction zone 50 million years… Read more2024-11-16 Megan Anderson – Siletzia’s influence on the Seattle Fault

2025-01-11 Paul Bierman – When the Ice is Gone
THE LECTURE: Cold War Science and Engineering Today Reveals Greenland’s Fragility in an Overheating Climate Greenland, a remote Arctic Island, holds in its ice enough water to raise sea level over six meters. That is enough to flood every major coastal city and displace up to half a billion people. Yet, until recently we knew very little about the past comings and goings of this massive ice sheet. Through the lens of climate science, environmental history, and the stories of people who studied Greenland over the past century, Paul will use the past to look into a warming future. He… Read more2025-01-11 Paul Bierman – When the Ice is Gone

ABOUT US
Our goal is to foster an understanding of Earth Science concepts by offering 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.
