We went on a field survey at Abira golf course again.
This time, the excavation was done using an excavator instead of manual labor. Mr. Hara obtained a license in Yamanashi Prefecture beforehand, so he was able to operate the excavator.
Mr. Ali, a newcomer to Kuwano Lab, also worked very hard.
In the end, the size of the hole was over 2 meters.
We are now analyzing the results of the surface wave/reflected wave survey and hope for good results!
