Experts Say Liquefaction Can Occur in a Portland Earthquake


An Oregon State engineering professor has been studying the "liquefaction" that happened during the Japanese earthquake. Scott Ashford says if its supported on shallow foundations or a mat foundation, you can get significant settlement.  He says that settlement can tear out power and gas lines and cause landslides.

He also says Portland has soils similar to those in the Japans' quake area and would see the same impact.
