The Pacific “ ring of fire” doesn’t stop at the equator. While my print story and post on quake threats last week focused on the seismic peril facing millions of poor people living in fast-growing cities in quake zones, there are plenty of prosperous places that have not adequately responded to their exposure to enormous, and inevitable, earthquake risk. A prime case in point is Oregon. After the destruction of hundreds of poorly built schools in China’s Sichuan province, I wrote repeatedly here and in print about similar vulnerability identified by engineers and seismologists in that state, despite the clear record of devastating quakes and tsunamis generated by the Cascadia fault beneath the sea bed off the Northwest coast.
