A rockfall protection embankment is an earthwork built in elevation with respect to the ground to intercept falling rock fragments before elements at risk such as roads and buildings are reached. This term is widely used in the rockfall community but the terms bunds and walls are sometimes used as alternatives.
The rockfall still takes place but an attempt is made to control the outcome. In contrast, active mitigation is carried out in the initiation zone and prevents the rockfall event from ever occurring. Some examples of these measures are rock bolting , slope retention systems, shotcrete , etc.
The National Disaster Risk Reduction and Management Council (NDRRMC), formerly known as the National Disaster Coordinating Council (NDCC) until August 2011, is a working group of various government, non-government, civil sector and private sector organizations of the Government of the Republic of the Philippines established on June 11, 1978 by Presidential Decree 1566.

The Philippines raised the alert level at the popular Mayon volcano by a notch on Thursday, after detecting volcanic earthquakes and hundreds of rockfall events. At "alert level 3" on a scale of 5 ...
Some landslides are complex in the sense that they feature different movement types in different portions of the moving body, or they evolve from one movement type to another over time. For example, a landslide can initiate as a rock fall or topple and then, as the blocks disintegrate upon the impact, transform into a debris slide or flow.
Talus cones produced by mass moving, north shore of Isfjord, Svalbard, Norway Mass wasting at Palo Duro Canyon, West Texas (2002) A rockfall in Grand Canyon National Park. Mass wasting, also known as mass movement, [1] is a general term for the movement of rock or soil down slopes under the force of gravity.
Geomats are anti-eroding biomats or bionets that are purpose-made synthetic products for the protection and grassing of slopes subject to surface wash. Geomats provide two main erosion control mechanisms: containment and reinforcement of the surficial ground; and protection from the impact of the raindrops. Geogrids made of geosynthetic materials
A rockfall barrier is a structure built to intercept rockfall, most often made from metallic components and consisting of an interception structure hanged on post-supported cables. [ 1 ] Barriers are passive rockfall mitigation structures adapted for rock block kinetic energies up to 8 megajoules.
