Portland is earthquake country. Three different types of earthquakes are possible in Oregon with two creating big threats for Portland. One is movement on local faults in the Portland area like the Portland Hills Fault. The other is the “Big One’ that could generate a magnitude of 9 along the coast and could last three minutes. Portland would be greatly affected by both.
Dr. Burns will talk about the sources of these quakes and their past history and future chances and specifically will talk about both Haiti and Chile and their relevance to Oregon. Chile is a perfect example of what could happen in Oregon with the Big One.
