Nepal has a complex geographical landscape with rugged terrains, deep valleys, and hilly regions. The unstructured and unscientific development in these areas poses risks and vulnerabilities, among which landslides are one significant hazard.
According to the National Disaster Risk Reduction and Management Authority, there have been 554 reported landslide incidents in Nepal in the past year alone, resulting in the loss of 101 lives and leaving 22 others injured. Additionally, around 61 crores Nepalese rupees worth of economic damages were recorded.
Landslides are a natural disaster, and they can strike at any time. However, using technology can help reduce the risks associated with landslides. One such technological tool is the “Landslide Early Warning System,” also known as the “Pahiroko Poochchavni Pranali” in Nepali.
Ram Laxman Inovexon, a company working in the field of technology for a long time, developed this system in Nepal around four years ago. The company has installed this device in various locations across the country, including Gorkha and Butwal.
The “Landslide Early Warning System” includes three sensors: a rain sensor, an inclination sensor, and an accelerometer. The rain sensor measures rainfall in millimeters, helping to detect heavy rainfall that could trigger landslides. The inclination sensor and accelerometer detect any changes in the slope or sudden movements, respectively, providing critical data to assess the potential landslide risks.
The system works wirelessly and is powered either by a lead-acid battery or solar power. It can monitor data every five seconds and displays it on its screen. If the sensor unit detects conditions that might lead to a landslide, it triggers an alarm (siren) to warn people of the potential danger.
The device is designed to withstand temperatures ranging from -20 to 60 degrees Celsius and has a frequency of 315 MHz for wireless communication. The company is working on research and development to improve the design and functionality of the system and has provided it at a relatively lower cost to make it more accessible to communities.
With the “Landslide Early Warning System” in place, people in landslide-prone areas can be alerted in case of potential danger, allowing them to take preventive measures and evacuate to safer locations, minimizing human casualties and damage to property.
Although the system can’t prevent landslides from happening, it can significantly reduce risks and provide early warnings, giving communities valuable time to respond and ensure their safety. The company aims to collaborate with local authorities and further upgrade the system to enhance its effectiveness and reach.
