The persistent vulnerability is not limited to remote regions of developing countries, but extends to the city centers of places as cosmopolitan as Portland, Ore., and Istanbul, both of which face looming seismic shocks. Yumei Wang, the director of Oregon's geohazards team, said a quick evaluation last year found that 1,300 of the state's schools (housing 340,000 students) and emergency-services buildings had a “high or very high” risk of collapse in a substantial earthquake. And the region faces the near-inevitable prospect of a great earthquake on the Cascadia fault, possibly a 9.0 — 32 times more powerful than the 8.0-magnitude temblor in Sichuan. The last such quake there occurred in 1700, raising a tsunami potent enough to be recorded in Japan.
[I]n Oregon, there are more than 90,000 kindergarten to high school students going to schools in structures that have a very high potential for collapse. There are more than a quarter million more K-12 students going to school in structures that have a high potential for collapse. That puts more than 340,000 of Oregon's K-12 schoolchildren in buildings that have high and very high collapse potential in a seismic event.
