JAKARTA - The phenomenon of land movement in Buluroto Village, Banjarejo District, Blora Regency, Central Java, is reported to be spreading. This condition is marked by the emergence of a new crack that is about one meter from the old crack that had previously formed in the area.
The head of the Banjarejo Police, AKP Gembong, said that the movement of the earth caused a decrease in the surface at a number of points with a depth ranging from 40 to 50 centimeters. In fact, the land subsidence is now spreading to areas that were previously not affected, including approaching residential areas.
"Soil movement not only occurs at the initial location, but has spread to the neighborhood of residents' homes," he said when confirmed in Blora, Friday.
As a result of this incident, at least three residents' houses and livestock sheds were affected. Two of them were reported to have suffered quite severe damage, with the condition of the house walls falling to about 50 centimeters. The length of the affected area is estimated to be 200 meters. However, the direction of the soil movement is no longer extending, but rather spreading to the other side, including towards the settlement.
One of the affected residents, Peniwati, revealed that for about a month he was forced to do the back of his house's kitchen. The back was done using materials transported by one colt car and one truck, in an area of approximately 7 meters by 5 meters.
Another resident, Nur Hidayah, also experienced a similar condition. The land around his house was reported to have collapsed with a length of about 6 meters and a width of 4 meters. Meanwhile, Sahid, a local resident, said his land was also affected with an area of 12 meters by 9 meters.
According to residents, this kind of land movement had occurred in 1998. At that time, the land collapsed to a depth of about two meters vertically, not leading to the river. The impact, the floor of the residents' houses experienced cracks.
Sahid added that currently the land subsidence is still taking place almost every day with a range of 2 to 3 centimeters. When heavy rain falls, the decline can reach around 5 centimeters.
He hopes that the village government together with related institutions will immediately conduct a direct review and technical study to find out the exact cause of the land movement and determine the appropriate handling steps.
Meanwhile, the Public Works and Spatial Planning Office (PUPR) of Blora Regency together with the Pemali Juana River Basin Agency (BBWS) have followed up on complaints from residents in Sambiroto Village, Buluroto Village. The temporary movement of the land was triggered by the flow of the Lusi River.
Head of Water Resources, Blora PUPR Office, Surat, said that the field inspection with BBWS Pemali Juana was planned to be carried out next week. Until now, the village has not submitted an official report regarding the incident to the Blora Regency PUPR Office.
