Cirebon Regency is prone to soil movement, especially when precipitation is above normal, while the area of the collapse has a cliff slope, the chief of the ministry’s geological agency, Muhammad Wafid, said in the statement.
Wafid said the undercutting method used in the open mining area and the steep slope may also have played a role in the collapse.
“While carrying out evacuation and search efforts, (rescuers) must pay attention to the weather and steep slopes, and not carry out activities during and after heavy rain, because this area still has the potential for further landslides that could hit or bury officers,” Wafid said.
