Kirk with another update on the rain. The images are from the following TKU video (click on the click to view the Japanese video; it includes reports on several different kinds of damage). I heard on RKK that the rain loosened the earth that the roots were clinging to and that that led to the tree's collapse. If the tree had fallen in a slightly different direction, it would have damage the walls shown in the second picture. Those walls were severely damaged in the 2016 earthquake and repairs on them had just ended.
