遺跡に見られる液状化現象の痕跡 Paleoliquefaction Features at Archaeological Sites in Japan
Liquefaction features from paleoearthquakes are common at archaeological sites of Japan. The most remarkable features are dykes of sand and gravel in which the clasts become finer approaching the surface. Liquefaction at some sites occurred not only in sand but also in gravel. Some archaeological features have been entrained and moved in sand intrusions.
