The Pacific Northwest Region of AGU held its 36th annual meeting September 28–30, 1989, at Portland State University, Portland, Oreg.; 78 scientists attended. The five sessions included tectonophysics, seismology, hydrology and contaminant transport, volcanology and other geology, marine geology and oceanography in 23 oral presentations and 9 poster sessions.

As in most regional meetings, no parallel sessions were used, thus exposing the audience to a wide variety of presentations. The tectonics section included papers on vertical deformation measurements along the Oregon Coast, evidence of the subducting plate using apparent velocities observed from subcrustal earthquakes, gravity modeling in the Portland Basin, and multichannel seismic reflection survey in the Queen Charlotte Basin.
