The 33rd annual meeting of the Pacific Northwest Branch of AGU (PNAGU) was held September 4, 1986, at the University of Washington, Seattle. There were several reports on exploration methods utilizing piezoelectric and magnetometer techniques. Most of the other reports emphasized tectonics, seismology, and paleomagnetics in the Pacific Northwest. New evidence was presented that volcanism in Washington has had a longer history than previously reported. The Washington Department of Natural Resources announced work on four revised geologic maps that cover the state of Washington at a scale of 1:250,000. These maps will be published from 1987 to 1992.
