(Portland, OR) -- The city of Portland is setting aside five-million dollars for seismic retrofits in historic Old Town-Chinatown. KGW-TV reports many of the 19th-century buildings in that area of Portland are especially vulnerable, because of their age and the fact they're constructed of bricks. Engineers with the state of Oregon say such buildings will be unable to withstand a quake that reaches a magnitude of eight or higher, which geologists say could hit the Pacific Northwest at any time. The urban-renewal money being earmarked will help Old Town building owners make seismic renovations to the structures.
