Considering the potential danger increasing during the rainy season, he advised residents to seek temporarily a safer shelter.
"I think that the community must first be relocated, we do not know how many cracks will occur, because it will be later the rainy season," said Adrin, Wednesday, October 17, 2018.
Tanah moves in RT 04 / RW 01, Kampung Kadu Sirung, Kadu Sirung Village, Pagedangan, Tangerang Regency, damaged roads and houses.
On the Tuesday afternoon of October 16, 2018, large and long cracks occurred on the neighborhood road of the village. The crack and the depth of 50 meters long vary from 0.5 to 1 meter.
Rumors that a house with a wall impacted on the ground, says Adrin, could endanger the inhabitants. The type of slow avalanches mainly causes damage to buildings. "The people who live there can become victims if the building cracks and suddenly collapses," he said.
According to Adrin, the cracks in the ground spread to the bottom of the building, and when there is still movement, the cracks at the base of the building spread to the weak parts of the building structure, especially the walls.
Other efforts if the community can not be evacuated, said Adrin, surveillance must be exercised in certain areas. While the local government is deemed necessary to implement an emergency response. "While badessing the level of threat and the possibility for the community to come back," he said.
According to him, the symptom of the soil crack is not a characteristic of liquefaction, but the movement of the soil that is a slow process or commonly called creep. The natural conditions of these shocks do not require steep slopes. The slope of the slope between the ground and the rock in the sloping area is sufficient to move the soil.
