Landslide Development Characteristics and Risk Zoning along the Dir Road in North Pakistan

Abstract Landslides are one of nature's most lethal disasters. They are defined as the movement of earth down a slope, a rockslide, a rockfall, or a debris flow. Landslides are far more dangerous than most people realize. Landslides occur for a variety of reasons, including environmental factors such as rock decay over time, rainfall, and flash floods, which can cause rockfalls and debris flow, or constructions along slope banks, which can weaken the slope and allow an earth mass (a combination of mud and rock) to slide downhill or natural phenomena such as earthquakes. Landslides destroy infrastructure, homes, businesses, croplands, highways, and commuter roads every year, resulting in thousands of fatalities and injuries and significant economic losses (both directly and indirectly). Landslides play an essential role in the evolution of landforms and pose a severe threat in many regions of the world. In some places, landslides cause more deaths and economic damage than other natural disasters, such as volcanic eruptions, earthquakes, and floods. Due to the wide range of landslide phenomena, no single method exists to identify and map landslides, establish landslide hazards, or evaluate the associated risk factors. landslides, NE to landslides, and identifying risk zones and analyzing the dynamics of landslide development is critical for reducing the risk to human life and infrastructure.
