Weve seen localized3 examples of soil liquefaction as extreme as this before， but the distance and 2 of damage in Japan were unusually severe， said Scott Ashford， a professor of geotechnical engineering4 at Oregon State University5. Entire structures were tilted and sinking into the sediments， Ashford said. The shifts in soil destroyed water， drain and gas pipelines6， crippling the utilities and infrastructure these communities need to 3 . We saw some places that sank as much as four feet. Some degree of soil liquefaction7 is common in almost any major earthquake. Its a phenomenon in which soils soaked with water， particularly recent sediments or sand， can lose much of their 4 and flow during an earthquake. This can allow structures to shift or sink or 5 . But most earthquakes are much 6 than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in situations such as this. |
