Let's consider "ground" including the "surrounding environment."

In July of this year, heavy rains caused flooding across western Japan. I would like to express my heartfelt sympathy to all those affected.
The heavy rains that occurred throughout western Japan brought about what is said to be the worst damage in the Heisei era. Among the areas most severely affected was Hiroshima Prefecture, where experts have pointed out that the local soft ground was a contributing factor.
The soft ground seen in Hiroshima Prefecture is known as "masago soil," which is formed from the weathering of granite. It is believed that the soils found on the surface of mountainous areas triggered numerous instances of "shallow landslides," where the soil slid down the slopes due to the concentrated heavy rainfall.
Traditionally, "ground diagnosis" mainly involved investigating the sturdiness of the land where buildings are to be constructed. However, in light of the recent damage, it can be said that the importance of investigating the surrounding environment has increased significantly. No matter how sturdy the land where a building stands may be, it is no match for a mudslide that rushes in.
Investigating the land, including the surrounding geology and environment, can be quite challenging for the general public. Therefore, when choosing land or a house, I encourage you to first consult with local construction companies or other experts.
