Landslide Detection Method using Laser Beam

Events of landslides in the tropics often occur, and the main causes of these events are often caused by the high intensity of rainfall. Before an avalanche occurs, it will usually be preceded by land movements that can occur slowly (creeping) or fast, depending on the condition of the type of soil that exists in that location. Some ground motion detectors include sliding stakes and inclinometers. This tool is useful as a measure of the amount of movement, especially on sloping land. The purpose of this study is to make a movement detection device that can be an alarm or early warning for residents who live in locations that are prone to movement. The benefit for science is the development of monitoring methods using laser light that have not been done so far. The results of this study will be useful for the development of methods for measuring land shifts. The signal is sent using an internet network, so that it can be monitored continuously. The significance of this research for science is the development of a method of applying sensors using laser light which has not been done so far. Recording is done by using a web-based data logger by sending visual measurement data to the data center. The accuracy of the laser beam that spreads when it is received on the target board, is done using the center cluster method.
