On Wednesday, Nov.17, from 7 p.m. to 8 p.m. at the Tigard Public Library, Oregon author and hiking expert William Sullivan will tell the dramatic story of the floods, earthquakes, forest fires, eruptions and tsunamis that have shaped Oregon over the past 13,000 years. Giant earthquakes and tsunamis devastate western Oregon every 300 to 600 years. The last one hit in 1700.
Sullivan will also discuss the cycles behind the area's natural disasters and examine what may happen when the next "big one" strikes. He is the author of 14 books and numerous articles about Oregon, including the "Oregon Trails" column for the Eugene Register-Guard.
This free program will be held in the Library's Community Room. No registration is required. For more information, visit the Library's website at http://www.tigard-or.gov/library or call the Adult Reference Desk at 503-718-2517.
