We went to the Shiraizuka Kofun at Komae-city to conduct the surface wave survey.

This Kofun is surrounded by many the housing.
The geophone(sensor) has some needles to integrate the sensor and the ground, the length is about 7cm.
About needles, they don’t want us to push into the ground, if we can.
Our general survey, we don’t care about restration to the original state.
But in case of Kufun, It was very strict.
The target was the object about 3 meters off the ground.
We got the interested wave data, now Hara-san under analysing them.
