Mass Movements Mass Movements Mass movement (commonly referred to as landslides) represents a geological process where surface materials move downhill by gravity. Most of the Martian mass movements occur in Valles Marineris, the Grand Canyon of Mars. Figure 2.1 shows a section of a collapsed canyon wall. At the top of the picture, a rock avalanche at the three curved walls is clearly visible. There is also a large amount of debris accumulated at the foot of the walls. A close-up view of the central curved wall is shown in Figure 2.2 . The fan-shaped feature at the bottom is the front of a debris flow on the valley floor. Figure 2.3 is another view of debris that piled up to modify the valley floor on a large scale. Notice the lineated tectonic grabens on top of the plateau. (Graben represents a downthrown block of land mass produced by horizontal tensions.) The existence of these linear grabens suggests that Valles Marineris was probably formed by horizontal stretching of the regional tectonic stresses. Another interesting feature occurred on the valley floors of the fretted or chaotic terrain as shown in Figure 2.4 . Notice the lineated features on the valley floors. They were probably formed by the debris deposits coming off the steep walls. There may be some slow, glacier-like, down-slope movements parallel to the lineations, but much of the movements are in the direction perpendicular to these linear features.

The Lower Greensand Escarpment in S. Kent, UK, and its landslips Preliminary : November 1998 The landslides of the Lower Greensand Escarpment, Aldington to Sandgate, are the subject of considerable research. Here are a selection of references: 7th International Symposium on Landslides, Trondheim, Balkema, 1243- 1250. Location plan for places mentioned in the text. Note: Stutfall Castle (Roman) at foot of slopes under Lympne Castle (Medieval, with late c19th and early c20th additions). This is the key to the air photo of the 1988 landslide. The landslide, which was the reactivation of old landslide remnants, occurred following a period of wet weather. Movements at the head of the rotational slide zone are shown here.

LANDSLIDES !! AN ALERT "TALK STORY" Acknowledgments: The images used in this "talk story" are taken from the Natural Hazards Image Archive prepared by the U.S. Geological Survey The images contained in the Natural Hazards Image Archive are formatted and presented by the Jet Propulsion Laboratory's Data Distribution Laboratory (JPL-DDL) for general use. All of the images are from an United States Geological Survey Photo CD-ROM, and represent a sampling of the U.S.G.S. photo archive collection. Many of the images are priceless from both an historical as well as geological standpoint. The Natural Hazards Image Archive is part of an on-going effort by the JPL-DDL to create a user-friendly archive of U.S. government scientific CD-ROM information. To that end, the JPL-DDL has developed a Government CD-ROM archive that lists the contents of over 400 U.S. Government science CD-ROMs. Another government entity that has extensive archives of natural hazard photos is the NOAA/NGDC, which can be reached at NOAA Natural Hazards .

Earthquake-Induced Landslides Earthquake shaking can cause landsliding on many scales, as some of these examples show. An earthquake can cause a slope to become unstable by the inertial loading it imposes or by causing a loss of strength in the slope materials. This large slide temporarily blocked a river following the 1999 Chi-Chi earthquake in Taiwan. The river eventually formed a path around the slide and began to erode the slide materials. Note that the hillside was covered with vegetation before the slide, and hence the exposed bedrock marks the boundary of this large slide. This building hangs over the head scarp of a landslide in decomposed bedrock that was triggered by the 1995 Kobe earthquake. Several homes were buried and over 30 people killed by the landslide. A large slide formed beneath portions of the central switching station for Taiwan during the 1999 Chi-Chi earthquake. The slide movements of about a meter caused extensive disruption to the station, resulting in extended disruption to power supplies in Taiwan. This photo shows the scarp along one side of the slide mass notice the offset in the pavement and bends in the pipes. [Accompanies above slide] The head scarp of the slide passed through a system of transformers. While the movements are not as dramatic as many other large slides, the economic consequences of this slide were tremendous because of the impact that power losses had on Taiwanese industry.

Read more about this map close this text box Map Sources Abstract Landslides are mass movement of soil and rock. They have resulted in several hundred deaths in Canada, and caused billions of dollars in damage. There are different types of landslides: rock avalanches, caused by the failure and disintegration of a large rockmass with a rapid downslope movement of the debris into the valley. Rockslides are a mass of rock that slides, on short distance, on the detachment surface. Rockfalls are a small rockmass that disintegrates into many blocks falling, bouncing and rolling down a steep slope. Debris flow happens when surficial material is saturated with water, usually caused by heavy rains. There are also debris avalances. These occur on the slopes of volcanoes and are large rapid mass movements of volcanic rock, but they have not occurred recently in Canada.

Seemingly insignificant modifications of surface flow and drainage may induce landslides. In an urban setting, improper drainage most often induces disastrous sliding. The placement of buildings, to capture a spectacular view, on slide-prone coastal dunes, eroding headlands and sand spits, or at the edge of a receding shoreline, may lead to the loss of the structure. It has been noted that in Portland, population pressure has pushed construction into many areas and sites previously rejected as landslide-prone. Agricultural irrigation and forestry practices such as clear-cutting and stripping vegetation from naturally oversteepened slopes have been shown to be responsible for a spate of landslides. Highway construction on similar slope conditions awaits only the first good rain to provoke earth movement. In an urban setting, improper drainage most often induces disastrous sliding.

HazardWatch Among the most dangerous processes are deep-seated landslides, such as the 1991 collapse of the summit area of Mount Cook, and the 1979 Abbotsford landslide that destroyed 63 houses in southern Dunedin, fortunately without loss of life. Understanding the processes that lead to slope collapse and the subsequent landslides, provides fundamental knowledge about evolving landscapes, and essential information for safety. The Falling Mountain rock avalanche, triggered by the 1929 Arthur’s Pass earthquake, resulted in 55 million cubic metres of rock spread 4.5 km down the valley. Probably the most significant catastrophic landslide in New Zealand is the Green Lake landslide near Lake Manapouri. This 26 cubic-kilometre slide occurred about 13,000 years ago due to the collapse of 10 km of the Southern Hunter Mountains. It may be the world’s largest
