Mountain's Sign / landslide prevention net

Thousands of and tens of thousands of earthquakes have hit the world and hence the severe casualty has ensued. Further, numerous earthquakes are expected to hit the world regardless of the magnitude.
We propose a new concept of landslide prevention net, considering landslides are a second damage following earthquakes. The conception of ‘MOUNTAIN’s SIGN’ has come from the ‘Big Dipper’ that guides people when they are lost.
Thee axes become a unit underpinning the mountain. When it feels a quake, red lights are turned on to send a danger signal.
