Landslides can be triggered by many, sometimes concomitant causes. In addition to shallow erosion or reduction of shear strength caused by seasonal rainfall, landslides may be triggered by anthropic activities, such as adding excessive weight above the slope, digging at mid-slope or at the foot of the slope. Often, individual phenomena join to ...
Disaster risk reduction (DRR) is defined by United Nations Office for Disaster Risk Reduction (UNDRR) as those actions which aim to "prevent new and reducing existing disaster risk and managing residual risk, all of which contribute to strengthening resilience and therefore to the achievement of sustainable development".
Tornadoes can also be spawned as a result of eyewall mesovortices, which persist until landfall. [3] Over the past two centuries, tropical cyclones have been responsible for the deaths of about 1.9 million people worldwide. Large areas of standing water caused by flooding lead to infection, as well as contributing to mosquito-borne illnesses.
A weir was built on the Humber River (Ontario) to prevent a recurrence of a catastrophic flood. Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human
New drilling in Rancho Palos Verdes has revealed that devastating land movement has been caused, at least partially, by a deeper slip plane — meaning a larger area could be affected.
An ongoing crisis stemming from a widening landslide is threatening multimillion-dollar homes in the Southern California city of Rancho Palos Verdes.. The landslide grew worse over the weekend and ...
The smallest value of the safety factor will be taken as representing the global stability condition of the slope. Similarly, a slope can be locally stable if a safety factor larger than 1 is computed along any potential sliding surface running through a limited portion of the slope (for instance only within its toe).
A landslide that killed 31 people, including 13 children, at an unlicensed Malaysian campground last year was caused by persistent heavy rain, not human activity, a government investigation concluded.
