The earth strain has been observed simultaneously by strain gages and extenso meters in the tunnel of the Nokogiriyama Crustal Movement Observatory during the period from January 1986 to March 1987. The data processing is made by the least square method and the BAYTAP-G program. The strain response to atmospheric pressure changes are much affected by the topography over the observational tunnel. Tidal factors obtained by extensometers are 210 times greater than those obtained by strain gages.
