The Siparia Borough Corporation has restricted entry into the landslide zone at the Los Iros Royal Engineer Road, because of hazardous conditions caused by soil instability.
Due to the continued risk of ground movement, it is urging residents, visitors and all members of the public to avoid the affected area until further notice.
The Geological Society has recommended creating real-time warning systems to trigger evacuation alarms in the event of future incidents.
But for now, it said the focus should be stabilising the land north of the affected areas to prevent further inland movement.
To date, the situation has damaged 62 acres of land, with many acres of crops affected.
