}} In the year of 2012 the NARO[1] announced an in-situ ground survey machine, the Nippon Screw Weight System (NSWS),[2] designed to overcome problems with the standard penetration test;[3] The NSWS was developed with the specific aim to encounter the recent weather abnormalities and natural hazard, saving human lives.[4] The creator of NSWS, Kozo Okita, was the member of 311 earthquake disaster committee [5] of the Japanese Geotechnical Society.[6] The society released a report in June, 2012 proposing to Japanese government a use of NSWS to investigate the 3.11 aftermath.[7]It is compact, weighs 120 kg,[8] and highly-mobile because the wheels are attached, suited to measure the ground in the crowded residential areas.[9] It costs about only half of what used to cost with the conventional SPT test and triaxial compression test.[10] The NARO has released the cost index table.[11] Features for detecting weak spots:
Features for conducting in-situ shear test and sampling at a different hole:
Features for conducting Stability Analysis:
