How do mine operators/managers/engineers know, days/weeks in advance, that a land slide is going to occur?
In: Engineering
They pay a lot of attention to how the ground behaves. In general landslides tends to start very slowly, as in millimeters a day. It may be hard to see this unless you know what to look for. You might see some cracks appear slowly or a level road might not be level any more. But they also use more sensitive equipment to measure the movement of the ground around things like mines and construction zones. And if they catch the landslide early then they might have time to do something about it. If not then just evaccuating the area helps a lot.
