Landslide monitoring using global positioning system and inclinometer techniques

Landslide is one of the prominent geo-hazards that continuously affect many tropical countries including Malaysia, especially during the monsoon seasons. For the past 25 years, landslides have occurred throughout the country that caused property destruction and loss of life, especially near the hill...
