Liquefaction test carried out by simulating earthquake

SAPPORO, Japan - Engineers from the Ministry of Land, Infrastructure and Transport and the Port and Airport Research Institute created a state of liquefaction (photo) by simulating an earthquake at an experimental airfield in Otaru, Hokkaido, on Oct. 27. The earthquake was simulated by sequential blasts over two minutes of 1.8 tons of explosives buried in 580 locations, according to engineers who took part in the project. The experiment showed that there were no signs of liquefaction in areas injected with water-solidifying chemicals, they said. (Kyodo)
