	Mass Movements Information
		Mass movement or mass wasting is movements of masses of bodies of soil, bed rock, rock debris, soil, or mud which usually occur along steep-sided hills and mountains because of the pull of gravity.
		However, the trigger mechanism for mass movement is the gravitational pull of the earth on soil, rocks, and mud.
		Factors that affect mass movements are the steepness and instability of slopes, the nature of the slope materials, and the amount of water in material.

	The Black Commentator - Cover Story: It’s Time to Build a Mass Movement - Issue 144
		Mass movements don’t happen without masses. A mass movement whose organizers cannot fill rooms and streets, and sometimes jails on short notice with ordinarily non-political people in support of political demands is no mass movement at all. Organizers and those who judge the work of organizers must learn to count.
		Mass movements look to themselves and their shared values for legitimacy, not to courts, laws or elected officials. A mass movement consciously aims to lead politicians, not to be led by them.
		Mass movements are supported by lots of vertical and horizontal communication which reinforces the core values of the constituency and emboldens large numbers of ordinarily nonpolitical souls to engage in personally risky behavior in support of the movement's political demands.

	Mass Wasting (Site not responding. Last check: 2007-10-28)
		Mass-wasting is the down-slope movement of Regolith (loose uncemented mixture of soil and rock particles that covers the Earth's surface) by the force of gravity without the aid of a transporting medium such as water, ice, or wind.
		Thus, down-slope movement is favored by steeper slope angles (increasing the shear stress) and anything that reduces the shear strength (such as lowering the cohesion among the particles or lowering the frictional resistance.
		The down-slope movement of material, whether it be bedrock, regolith, or a mixture of these, is commonly referred to as a landslide.

	Critical Mass - Wikipedia, the free encyclopedia
		Some Critical Mass fans defend the lawlessness of cyclists based on their belief that typical laws governing bicycle road users are unfair and different from those governing pedestrians and motorists, and that traffic law heavily favours motor vehicle use in many cities.
		Critical Mass is undeniably linked to the environmental movement, which cites private automobile use as catastrophic to our global and local environment, in physical and social terms.
		The first San Francisco Critical Mass ride began in 1992 and its name soon began to be adopted as a generic label by participants in similar but independent mass rides which were starting to occur worldwide at around the same time, and some before then.

	Mass Movement
		Mass movement is the down slope movement of earth materials under the influence of gravity.
		The movement, especially in the case of slides and slumps, is along a failure plane.
		Soil creep is nearly imperceptible to the naked eye as it is the slowest of all types of mass movement.

	10(x) Hillslope Processes and Mass Movement
		Outputs to hillslopes occur by evapotranspiration, by percolation of water and the movement of dissolved substances into the bedrock, and by removal of sediment by streams by glaciers or by ocean waves and currents.
		Mass movement on this type of hillslope occurs primarily by way of localized sliding or rolling of a relatively small number of particles.
		This type of mass movement is known as a debris flow.

	Mass movement control (Site not responding. Last check: 2007-10-28)
		Mass movement control tends to be both expensive and far from simple.
		Unlike sheet or linear erosion control, mass movement control often means preventing rainwater from soaking into the soil, adding to the weight of the soil cover and rapidly reaching the slide bed-plane.
		Mass movement control must be primarily preventive: e.g., mapping vulnerable zones, drawing up a land use plan, banning building work or any modification of slopes, and protection in the form of coppice forests.

		Mass movement or mass wasting refers to the slow or catastrophic (rapid) movement of soils, sediments and rocks down hills, mountains, or other slopes on land surfaces.
		Mass movement may be triggered by catastrophic events, such as floods, earthquakes, or heat from volcanoes (lahars).
		Like erosion, human activities may promote or hinder mass movement by affecting slope inclinations, the amount vegetation on the slopes, the quantity of water in the slope materials, and the amount and the type of materials that are present on the slopes.

	National May 1st Movement for Worker and Immigrant Rights
		In 2006, history was made when the largest mass movement in the history of this country came to be.
		I designed and guided the political strategy parting from the history of this social movement since 1968 and it was inherently based on the present national and international political and social conditions, including the use of the corporate mass media.
		Today this movement, on par with the developments in Latin America moving away from the neo liberalist economic model and against transnational imperial dominance, is once again at a crossroads.

	MASS MOVEMENT IS THE KEY FACTOR FOR OUSTING THE ARROYO REGIME : QC IMC (Site not responding. Last check: 2007-10-28)
		The mass movement is not a field for the Arroyo regime to compete in.
		The mass movement is the ever developing and ultimate weapon of the Filipino people in view of the determination of the fake president and her regime to frustrate every proposal to bring out the truth and render justice on the charges against her for electoral fraud, corruption and other high crimes.
		The broad united front and mass movement must stay the course in arousing and mobilizing people in their millions all over the country and in raising the level of mass actions to a new and higher level until Arroyo understands the message that her regime must end or else.

	ZNet \|Activism \| It's Time to Build a Mass Movement
		Mass movements are nurtured and sustained not just by vertical communication, between leaders and constituents, but by lots of horizontal communication among the movement's constituency.
		Mass movements are creations of the political moment, rooted in the shared values of their core constituencies, nurtured by dense communications networks among a supportive population.
		Mass movements inevitably employ civil disobedience, and the civilly disobedient components of mass movements must be carefully calculated in such a way as to maintain support from broad sectors of the population it aims to mobilize, and to increase support if they are violently repressed.

	mass movement (Site not responding. Last check: 2007-10-28)
		In mass movement of soil - slides, slips, slumps, flows and landslides - gravity is the principal force acting to move surface materials such as soil and rock.1 When natural slope stability is disrupted, a range of complex sliding movements may occur.
		As a rule of thumb, rapid movements of soil or rock that behave separately from the underlying stationary material and involve one distinct sliding surface are termed landslides.
		Generally mass movement occurs when the weight (shear stress) of the surface material on the slope exceeds the restraining (shear strength) ability of that material.

		Movement occurs when slopes are steeper than the natural angle of repose of the material.
		A steep scarp surface exists at the top of the moving mass, and movement may be initiated by slope over steepening and aided by water infiltration.

	Amazon.com: The True Believer : Thoughts on the Nature of Mass Movements (Perennial Classics): Books: Eric Hoffer (Site not responding. Last check: 2007-10-28)
		He covers the appeal of mass movements and the desire for change found in potential candidates, the personality traits of potential converts, the unity and self sacrifice of the members that is necessary for the movement to achieve its ends, and the factors which determine the length of its active phase.
		Therefore a mass movement's appeal is not to those intent on bolstering and advancing a cherished self, but to those who crave to be rid of an unwanted self.
		Generically speaking, much of academic writing about the causes and nature of mass movements focuses on injustices imposed upon a certain class, race, etc., and the movement is largely reduced to pent up anger finally being united and simultaneously released by a charasmatic leader.

	THE ROMAN RITE -- Fr. John Mole
		Wild masses (1): This is a heading which refers to a phenomenon which has plagued the postconciliar liturgical reform from its beginnings and which alone justifies the existence of the Traditional Mass Movement.
		Whereas most Traditional Mass communities are in a precarious situation, subject to all sorts of vexations and vicissitudes, the monastery affords a stability and a prospect of steady growth and a bright future which, in turn, will help the more unstable lay communities to persevere and overcome their problems.
		The Traditional Mass movement needs a case that is well prepared and cogent enough, doctrinally and spiritually, to persuade bishops individually to accede to the request of the Holy See that they permit the ancient Mass to survive.

		The slope gradient is probably a major cause of mass wasting -- the steeper the slope, the less stable it is.
		In regions that are undergoing extensive chemical weathering, there is a higher probability of mass movement of the unconsolidated material (the regolith.)
		Would you expect the probability of mass wasting to be greater along a passive continental margin or an active continental margin?

		Mud flows - rapid downslope movement of debris or mud mixed with water (clay and silt mixed with water); Commonly occur in volcanic areas: most common type is a lahar, a volcanic mudflow (loose ash mixed with water), e.g.
		Rate of movement varies (less than 1 mm per day to several meters per day), but may be long-lived (days to years).
		Creep - the imperceptibly slow downslope movement of the soil and regolith in temperate climates due to seasonal frost heaving and thawing; evidence: tree trunks that are curved at the base, tilted trees, fence posts, utility poles, tombstones and causes retaining walls to be broken or overturned.
