 note = {The 1983 Japan Sea Earthquake(M=7.7)caused heavy damage associated with remarkable liquefaction to many houses and the ground soils at certain areas(2kmx6km)in the Noshiro City region, Akita Pref.  The geomechanical character of the ground there has been investigated through use of shear wave velocities from in-situ measurements, results of grain-size analyses, geoteclmical in formation from many drill holes and data for ground water depths. Almost all of the sites investigated in many places are underlain by loosely-packed sandy soils of fine-to medium-grained sediments(0.3 mm~0.5 mm), with low shear wave velocities less than 120m/s and small values of uniformity coefficients between 1.6 and 2.3. Seismic
microzonation maps showing areas  where local soil conditions would be favorable for liquefaction have been compiled for assessing future earthquake hazards in certain areas. In the Noshiro City areas investigated, all sites with shear wave velocities less than about 120m/s and with ground water depths less than 2 meters would be much likely to liquefy except for sites underlain mainly by silty and clayey soils. Sites with shear velocities greater than 150m/s would not have susceptibility to liquefaction.},
